One fish, two fish…175 fish?!

Along with tracking individual stoplight parrotfish, Sparisoma viride, our team has been busy conducting behavioral observations and getting GPS tracks of four other species of parrotfish for a total of 175 fish follows! It has been interesting to see how these species’ behaviors differ. While striped parrotfish (Scarus iseri) pay little attention to other males and do not defend their space on the reef regularly, other species, like the redband parrotfish (Sparisoma aurofrenatum), interact with conspecific males by flaring their dorsal fins as if to say, “this is my area, stay out!”

The redband parrotfish, Sparisoma aurofrenatum, will flash its fins at intruders instead of chasing them away like other parrotfishes.

One of Josh’s goals for the summer is to get a better idea about how terminal phase stoplight parrotfish interact with other conspecific males to defend their territory on the reef. During multiple dives, Josh and I followed male stoplight parrotfish and categorize the type and the duration of interactions with both terminal and initial phase fish. While males regularly chase smaller “floater” males (i.e., fish that do not possess a territory) out of their territory, it appears that males of similar size that share territory boundaries interact less often and less aggressively. . This “dear enemy” effect has been observed in several other species, but never documented in parrotfishes! Males will often interact with females in their territories. These interactions are usually brief and appear to be over feeding spots. However, on occasion we would see males chase females completely out of their territories, suggesting that maybe these females were not part of their harem.

In his previous work, Josh found that males of some species partition reef space into non-overlapping territories but share space with other parrotfish species. As part of Josh’s dissertation work, we wanted to observe how fishes interact within shared spaces. During days we were not diving, our team donned snorkel gear and headed to Invisibles and Aquarius to simultaneously track parrotfishes. During these tracks, I would follow a male stoplight parrotfish around the reef site while Josh followed a male queen parrotfish. For most of the follows, our fish generally did not interact much, often swimming by without paying any mind to the other. Occasionally, however, the two fishes would swim toward the same patch of the reef to graze. It was a moment of excitement for us on the surface – sometimes we would be so focused on following the fish and seeing which species got to graze at the coveted lunch spot that we would forget about the other person on the surface!

Josh hopes that these data will help us to better understand the drivers behind territory maintenance and space use in parrotfishes, which may have implications for the makeup of the underlying benthic community. This in turn could provide important insights into coral reef management to restore and maintain a healthy ecosystem.

The team is all smiles after wrapping up a great field season!

This summer has been packed full of field work both above and below the surface and I was able to learn a lot about the role of parrotfishes on coral reef ecosystems! I am so grateful that I was able to experience Bonaire for the first time with this amazing group of researchers. Thank you to Our World Underwater Scholarship Society and the American Academy of Underwater Sciences for providing me with the opportunity to be the 2021 Mitchell Internship, and to Josh Manning and the members of the McCoy lab at Florida State University for being such great hosts!

Final Weeks at REEF

We are officially in the last two weeks of the internship and I am not ready for it to end. This last month has been full of outreach events, diving, and surveying. Earlier this month was Rock the Dock, a REEF tradition held at a beloved local bar. It’s a cookout, hangout, and outreach event all at once, with free t-shirts included. What else could you ask for? We had a booth which included a nerf gun shooting gallery called Reef Protectors. The goal of the game is to shoot only the lionfish, leaving the other fish intact. Helping little kids with this game was fun and dangerous. I almost took a nerf dart to the face! All of the proceeds made by the bar, Sharkey’s, during Rock the Dock go back to REEF which is just one example of how much people care here in the Keys.

We’ve also had some great groups visit us this month. West Coast Connections, Road Scholars, and Road Less Traveled are all education groups that take like-minded people from across the country and bring them on adventures to different areas. We got to be a part of their journey to the Keys, giving them presentations on Fish ID, Invasive Species, and Florida Keys Ecology while they were here. West Coast Connections spent the most time with us, which was a ton of fun. All the kids were in high school and interested in marine science, so we got to foster that love by taking them snorkeling on local reefs and kayaking through the mangroves at Pennekamp State Park. I loved working with the group for a full week and getting to see them grow as they learned how to ID fish and then saw those fish in their habitats on the reef. I will never get tired of how excited kids get when seeing fish that they know!

I will also never get tired of the diving down here. Most of the dives that I have completed have been on shallow, high profile reefs. I’ve slowly been collecting a life list of fishes that I have seen. Most recently, I saw the Greater Soapfish which has been on my list forever! Unfortunately for my friends, as I learn the smaller fish, like Gobies and Blennies, I have been spending more time staring at the sand for entire dives. Most dive shops know to let us go unguided now. While everyone else is looking for the Eagle Rays and turtles, the REEF group is trying to find the Goldspot Gobies and Redlip Blennies, fish that are only a couple inches long maximum. Next week we are planning to dive another well-known wreck down here, the Eagle, which I am so excited for! This summer was my first experience with wreck diving, and now I can’t get enough. I love exploring deep wrecks and feeling like we are the only people in the ocean when we are down there.

Right after I saw a Soapfish!

We are planning to make the most of the last two weeks here, with as much diving as possible, a trip down to Key West, and even more education events. I am not ready to leave the Keys or the family that I have found down here, so I will continue working in Key Largo for an organization called MarineLab, a marine science education organization. I am so excited for the next step of my Keys adventure and owe it all to REEF and OWUSS!

The Adventure So Far

I began my internship here at the Reef Environmental Education Foundation a little over six weeks ago but thinking back on everything I have done so far it feels like I have been here for years. My weeks at REEF have been jam-packed with activities and learning experiences, and they have also been full of fun with the best coworkers anyone could ask for! My journey here started with an unexpected complication when I dropped a fridge on my leg the day that I left for the Keys, and I was anxious about starting this new chapter of my life straight from the hospital. The second that I met my housemates/coworkers, all my stress disappeared. My fellow interns, Hailey and Maddie, are the sweetest, friendliest people I’ve ever met and getting to go through this internship with them so far has been an unbelievable amount of fun!

Our first few weeks here were orientation and a steep learning curve. Originally, we were supposed to go straight into the water but the weather was rough when we first got here, with waves at an average of 3-4 ft, so we weren’t able to go snorkeling and diving until week 3. On the bright side, the time that we lost in the water we made up for exploring our new home (and I didn’t have to plastic wrap my stitches which is always a bonus)! The former interns before us left a Keys Scavenger Hunt, which included going to their favorite café in Islamorada (the adjacent Key), wandering through an artist village featuring a giant lobster statue, and finding a plant nursery complete with chickens, a bunny, and dogs! Not all the lessons were as fun as this, but they were all equally important. A large part of orientation was learning our educational presentations by heart that cover our four main programs, and I am now an expert on lionfish/invasive species, Florida Keys Ecology, and our fish ID program!

Speaking of fish ID, survey trips are definitely my favorite part of this internship, even if it is so hard to choose. Our first survey trip was unsupervised, with just the three of us Marine Conservation Interns, and it was a challenge. If I can take any lesson from this internship so far, I will say that mistakes are far easier to learn from than getting things right on the first try, and this snorkel trip was a great example of this. The waves were rough and so was the current and holding onto our dive slates was more of a struggle than I thought it would be. Since then, we have all discovered our favorite survey set-ups, which is apparently a rite of passage here. I am now a level-2 surveyor and hope to achieve at least ten surveys before leaving!

Our first survey trip!

The diving here is incredible too! Only Maddie and I came into this internship with our certifications, but Hailey completed the last of her check-out dives this weekend which promises many group dives ahead. So far, I have only completed six dives, but all of them were unique and special. I have dived shallow wrecks at night, high profile reefs, and a deep wreck, which was exciting and a little terrifying. Below is a picture of my supervisor and I on our way to dive Spiegel Grove.

Something that I was most looking forward to this summer was our Ocean Explorers Summer Camp, which we are wrapping up this week. Even though it was a little exhausting (kids have so much energy!) I am so sad that it is over. I loved being able to introduce kids to my favorite parts of the ocean. Even though I only got three days with them, it was so special! I was able to take them snorkeling, kayaking, seine-netting, and many other fun activities. Our first week of camp was ages 8-10 and the second was 7-13. Working with a variety of age groups gave me different but equally fun experiences. I knew that I had a passion for educational outreach but working at camp confirmed this!

Giving my first official educational outreach presentation

While I don’t want to think of this internship ever ending, I am so excited for the next six weeks! I know that they will be just as fun-packed and educational as the last half, with new experiences and adventures. I am hoping to make it down to Key West with my roommates to see a sunset and go on a tour of all the best Key Lime Pie in the area (and maybe see a Key Deer!). I can’t wait to spend more time in the water now that the weather has started to calm down a little! More updates and pictures to come!

For the last two weeks of my internship, I shed the title of “scientific diver in training” and became an AAUS Scientific Diver thanks to Diana Steller, Shelby Penn, and my fellow classmates. The first week consisted of lectures on different topics including equipment, cylinders & regulators, species identification, dive emergency & rescue, diving physics, and diving physiology. After expanding our minds in the classroom, we enhanced our skills in the water. We had our checkout dives at Breakwater Cove (where I had my first cold water dive at the beginning of the internship). Then at Hopkins Marine Station, we had our first practice on Reef Check surveys.

Reef Check helps ensure the long-term sustainability and health of rocky reefs and kelp forests along the coast of California. They monitor rocky reefs inside and outside of California’s marine protected areas. Reef Check also provides scientific data (which is collected by dedicated volunteers) needed to make knowledgeable decisions for the sustainable management and conservation. Reef Check California volunteers are divers, fishermen, kayakers, surfers, and boaters! I am so happy that I had the chance to get involved with Reef Check this summer and for anyone living in California interested in diving and conservation, please volunteer! Check out their website to learn more.

We learned species identification of fish, abalone, crabs, sea stars, slugs/snails, sea cucumbers, urchins, kelp, and other algae. As a dive team, we conducted four different surveys: algae, fish, invertebrates, and uniform point contact (UPC) using 30 meter transect tapes. For algae, we counted individuals (only if they met certain length requirements) and recorded number of stipes for two species: Feather boa and Giant kelp in an area of 2 m across the transect. We also had to keep an eye out for algae species that are invasive including Caulerpa sp., Undaria sp., Sargassum muticum, and Sargassum horneri. For invertebrates, we counted individuals (of certain lengths) and recorded sizes of abalone. For fish, our instructors and trained volunteers counted and sized the fish that they observe in an area 2 m across the transect tape and 2 m off the bottom (30 m x 2 m x 2 m). The goal of UPC is to characterize the habitat so this survey combined cover, substrate, and relief at 30 points along the transect.

Top image- All of the students moving the zodiac into the water for our deep dive.

During the second week of the diving course, we camped and practiced more Reef Check surveys at Big Creek State Marine Reserve in Big Sur, California. Big Creek is a 14.51 square mile MPA that was established September 2007. This dive site is the perfect place to obtain our AAUS certification. There was an easy beach entry, a freshwater stream nearby to rinse off our equipment, grassy area for our belongings, and super thick kelp to explore in.

Top image- Students happily rinsing off in the stream after a long dive. 

Left image- View of the beach, bridge, and the mist during a break in between dives.

Right image- Our lovely compressor that we used to fill tanks while camping. 

Our normal day included waking up at the camp site, preparing lunch, walking to the beach, practicing as many surveys and we could on 2 dives, rinsing off in the stream, then continuing with lectures and/or exams. On our last survey day, Dan Abbott from Reef Check came to test us on our species identification skills. We then divided into 3 teams with each diver in charge of one specific survey. Each team had two transect sites to finish and luckily, we all finished them on the last day!

Bottom- (Left) Our first snorkel/kelp crawl at Big Creek (Right) More beautiful kelp. 

I couldn’t have wished for a better way to end the AAUS/OWUSS internship. This small group of people (there were only 7 students in our class) have become lifelong friends and dive buddies. From spending time every day with each other for two weeks, we all became very close and helped build one another’s skills and experience. Through difficult and hard times, we supported each other well and lifted each other’s spirits when they were low. Scuba diving is an activity where you trust your dive buddy with your life. This allowed us to build strong relationships and work together perfectly. We trusted each other to finish surveys as a team and most importantly, dive safe. We studied hard to remember the species we needed to know to conduct surveys and we quizzed each other until we all felt comfortable and confident.

Deepest thanks to Diana Steller, without her there is no way I would’ve obtained four diving certifications, completed Reef Check training, helped on multiple research projects in California and Mexico, and had the time of my life this summer. I’ve learned many lessons about marine science, diving, and life from Diana. Thank you to the people from Moss Landing Marine Labs, San Diego State University, and those who participated in the AAUS Scientific Diving Course for the adventures, shared laughter, and teaching me how to be a better diver, researcher, and person. I can’t wait to see the success of future OWUSS/AAUS interns and to follow in the footsteps of past researchers and scientists. Although this is my final chapter as the OWUSS and AAUS intern, I am looking forward to dive deeper into marine science in the future.

New Shores – REEF [4]

Bayside view from Sundowner’s, Key Largo. Taken while my parents were visiting near the end of my internship

Eleven weeks – it is strange to think how short my internship with REEF this summer truly was. I knew before arriving how fast the summer would go by, but the ephemeral nature of seasonal positions is always a little surprising. Before I reflect on my time in Key Largo, however, I would like to go back to this past April, when my experience with OWUSS really began.

I was just finishing up my senior year at the University of Kentucky, and I was juggling a lot of activities. The deadline for my senior thesis and poster presentation was coming up, and finals loomed just ahead. I was more than happy to take a break from finals and paper-writing the second weekend of April to travel up to New York City, a stark departure from the rolling hills of central Kentucky. This was to be an exciting weekend for several reasons – I had never been to the Big Apple, and I was about to be inducted as a member of both the Explorer’s Club and the Our World Underwater Scholarship Society. On top of this, I was about to meet back up with my friend Liza Hasan, who had recently accepted this years’ AAUS Mitchell Internship. Liza and I became good friends back in 2017 when we both studied abroad in Bonaire, at a research station focusing on tropical marine ecology. We were overjoyed when we found out we had both received internships from OWUSS, knowing how rare and unique of an opportunity this was for each of us. We would also have the chance to see our friend Shannon Brown again (who was the 2018 NPS intern), who was an intern at the Bonaire research station when we were students!

After a redeye flight out of Lexington to Newark, I took in the sights of the big city as I arrived via the bus system. New York was something else – unbelievably tall and expansive, home to countless people accomplishing a million different tasks. This past spring, I visited many big cities for the first time, from New Orleans to Atlanta to San Francisco, but nothing compared to this. The awe I felt simply rolling my luggage down the streets of Midtown Manhattan added to the feeling that I was stepping into an entirely new world with this internship.

The weekend would prove to be a whirlwind, what with meeting all the other interns, to official inductions at the top floor of the Radisson, to a night of dancing at 48 Lounge. We made a wild realization that four out of the five 2019 interns had all had Dr. Franziska Elmer as our research mentor at one point (including me and Liza). And this was all the first night! It turned out that Kyra and Abbey had both completed research projects under Dr. Elmer while studying abroad at the School for Field Studies in Turks & Caicos recently, while Liza, Shannon, and I all knew her through the Bonaire program. All of these seemingly random connections painted a beautiful picture of how the OWUSS community functions – it is there, in part, to get qualified young people in touch with the people they need to, in order to forge a path forward in the underwater world. This would become apparent the next day, when we had several socials and formal events at the Explorers Club and New York Yacht Club, respectively. Everyone in the society was incredibly excited to meet us and hear about our ambitions and university studies, as well as introduce us to past OWUSS interns and scholars. Hearing the presentations of each prior intern/scholar and how they were all going on to do amazing things in their fields directly after their experiences was inspiring. Not only that, but it was a challenge to do great things and build upon my own experience with REEF.

It was with that challenge that I returned to Kentucky to finish out my undergraduate career and then move on to the Florida Keys. But I had one surprise yet in store – just before leaving for New York, I had sent in an application to work as a Waterfront Assistant at the same field station that Dr. Elmer worked at in Turks & Caicos. Just before finals week hit in late April, I received an email saying I had been offered the job! I was both overjoyed and immediately stress-planning about how this would all work. Coming on as a Waterfront Assistant was contingent upon me completing my Divemaster (DM) certification over the summer, since I would start in Turks & Caicos in late August. Thankfully, REEF would end up being incredibly accommodating and allow me to complete my DM throughout the summer (read more here).

And that brings us back to the present. In the time since my last blog post, my time with REEF mostly consisted of wrapping up my personal project and working as a camp counselor once again. These coincidentally were my favorite aspects of being a REEF intern! The flexibility to pursue one’s own project at the REEF office (while not assisting with office work, lionfish derbies, Fish & Friends seminars, etc.) was exciting, especially because of the support offered by the staff. Two of the remote staff, Janna Nichols and Christy Pattengill-Semmens, were instrumental in helping me put together a Quizlet program, as part of the Learning Resources for the Volunteer Fish Survey Project. David gave me the idea early on to produce PowerPoint slides to help surveyors learn all the Beginner, Intermediate, and Advanced fish species of the Tropical Western Atlantic (TWA). I ended up using Quizlet instead, and developed lists of all the relevant species for each tier of difficulty, and then matching up photos with the common and species names of each species. Part of what was so exciting about this was that in the process I became much better at identifying TWA fish myself. What made this really rewarding, though, was the knowledge that my work would reach a wide, potentially international audience through the REEF website. Christy and Janna helped me get my Quizlets integrated directly into the website (see here). Not only that, but now REEF staff and volunteers are putting together Quizlets for every other region, making it truly accessible for anybody that wants to learn fish ID of a region anywhere in the world. One of my main goals going into the summer was to make the science that we do in the marine world more accessible, and I could not have been more satisfied with how this turned out.

It was (almost) always a joy working with the kids at Ocean Explorers Camp. Can’t beat a re-creation of the Titanic

As my personal project winded down, my last week at REEF ended up being as a camp counselor again. I never expected to love working with the kids as much as I did, but couldn’t have been happier having another go at Ocean Explorers Camp. This time I went in with a bit of experience under my belt, and made a commitment to do things a bit differently. I made a concerted effort to spend more time getting to know each camper, instead of just a few (as fun as getting chased around by Dakota the first week was!), and in doing so I feel that I connected with the kids pretty well. It was incredible seeing how quickly they could absorb knowledge about the ecology of the Florida Keys, and it gave me a chance to improve my interpretation skills. I have learned that kids in the 8-12 age range are perfectly equipped to learn a ton of information in a short amount of time, but only if you manage to keep their attention for more than a few minutes! A big part of that was figuring out how much each kid already knew about fish, corals, etc., and then not underestimating their knowledge, but instead building on what they already know and were interested in. I was surprised at how quickly I got back in the flow of being a counselor that week, and honestly I could see myself working in some marine education for children again in the future, whether through a job or as a volunteering effort. None of the kids gave me any adorable collages this time around, but I still felt a connection with them and won’t soon forget their unabashed excitement for the underwater world.

With that final week at REEF completed, my internship now consisted of intensive Divemaster training through the first week of August. I had finished the bulk of my training requirements throughout the summer, on days off and over the weekends, however there were still my final written exams. With some feverish last-minute studying and review of decompression theory, I passed both sections of the written exam! Now it was time to get more time out on the boat and actually leading dives. I had already led a couple dives, covered in my third blog, but it was important to see what it was like leading dives for tourists/locals of various experience levels from morning to close, and then coming right back the next day and doing it all over again. That is how I learned to deal with the random challenges that popped up day-to-day, such as what to do when someone’s gear from the prior day got left at home, or how to lead a dive for a customer who lost their certification cards. On top of that, I was very happy to get the extra experience leading dives/working the boat, since that is what I will be doing for students in Turks & Caicos for the next year. Key Dives was the perfect shop to learn from this summer, largely because it was such a small shop with a tight-knit staff. They all expected the very best of me and pushed me to learn from my mistakes after every dive, even the small ones. If I momentarily lost where the mooring line was and had to ask for a direction, you can bet I was given some constructive criticism about it back on the surface. I had to learn quickly, and ultimately it all paid off. By the end of my DM training, I was very comfortable leading dives, pointing out rare fauna unique to certain sites. I was lucky enough to spot more than ten bonnethead sharks on a dive over a seagrass-heavy area on my very last trip with Key Dives, and the group I was leading was loving it.

With that last day at Key Dives, my internship officially concluded. However, I will soon be taking everything I learned to new shores in Turks & Caicos. I can’t say enough how thankful I am to everyone at REEF for helping make this summer incredibly memorable, as well as vital for my professional development. With newfound experience in everything from K-12 outreach to dive briefing, I am equipped to move forward in the field of marine science as a much improved educator. My time at REEF may be over, but I cannot wait to see the great things that future REEF/OWUSS interns go on to do next year!

What is a Rhodolith?

By the end of this blog entry, trust me, you will know. From July 15th  to the 25th I had the pleasure of assisting on several different research projects around Catalina Island, California. After packing personal gear, dive gear, an inflatable boat, motor, and research gear from Moss Landing Marine Operations we set off for San Pedro. From San Pedro to Catalina (about a 5-hour drive), we discussed research projects and I grew more and more excited for diving around the island.

Avalon, Catalina Island

A clear day for diving at Avalon!

Diana Steller and Matthew Edwards are co-principal investigators on the main research project titled “Minimizing disturbance impacts by California vessel mooring systems on living rhodolith benthos in Catalina MPAs: an experimental assessment”. The project objectives are: “to identify and experimentally evaluate potential vessel mooring systems that may reduce impacts to rhodolith beds and other sensitive Catalina Island benthic habitats; to identify a suite of efficient field metrics to rigorously monitor integrity and recovery of rhodolith habitats; and to assess productivity and ecosystem functioning of rhodolith beds in order to evaluate restoration potential for recovery of impacted habitat.” (Steller & Edwards, SeaGrant). This involves many hours of scientific diving, lab work, and a few boxes of Oreos for energy.

A round rhodolith!

Scottie loves his greens!

Right on the day we arrived at Two Harbors (Big Fishermen’s Cove), I dove with the Survey Team at Emerald Bay. The Survey Team consisted of Diana Steller (Research Faculty/DSO of MLML and my internship host), Scott Gabara (Ph.D. candidate at San Diego State University and former MLML student), June Shrestha (MLML graduate student), and myself. Throughout the trip, we went to 6 different study sites and conducted benthic surveys inside and outside rhodolith beds.

Each of us had a different task and would attempt to complete them on dives that were a little over an hour long each. June conducted fish surveys and Scott would lay out the transect, identify the benthic substrate, count and identify the associated organisms on top of the rhodoliths within a 20 m transect. Diana and I would work with Scott on the same transect and use a 25 cm x 25 cm quadrat for substrate percent cover and we dug for organisms like snails, sea stars, urchins, and other small creatures. We also obtained sediment cores to collect live and dead rhodoliths to do size frequencies (where we took abundance in each size class and measured the volume).

Getting a rhodolith core isn’t as easy (or clean) as you think…

Another section of the Rhodolith project involved deploying underwater chambers. There were 10 chambers in total, some located within rhodolith beds and some on top of crushed rhodolith/sand habitat. Inside the chambers were sensors that took measurements of water quality. During chamber surveys, benthic details and cores are taken as well. An additional part of the chamber experiment involved crushing of the rhodoliths with chains to mimic the crushing action of mooring chains. A Tupperware, rigid cylinder, and a spoon were used to collect live rhodoliths in order to bring them back to the lab to find size-frequency for each within and outside rhodolith bed samples.

Some brittle stars wanted to say hello! (Look close and you can see their arms)

Now on to the important part: what is a rhodolith? How does it form a bed? Most people don’t know what rhodoliths are. One day, a local boater on Catalina asked us what we were diving for and we responded “we’re observing rhodolith beds” and he replied that there isn’t much to see there within the bays. But truthfully, a rhodolith bed is a whole new world. If you look up a rhodolith on Wikipedia, you’ll read that rhodoliths are “ colorful, unattached, branching, crustose, benthic marine red algae that resemble coral. Rhodolith beds create biogenic habitat for diverse benthic communities.” This is definitely true plus they deposit calcium carbonate within their cell walls so they form small hard structure just like hard corals do. However, rhodoliths are unlike coral since they don’t attach themselves to any rocky substrate or seabed. That’s why they’re often called tumbleweeds because they roll around the sand and have thin branches. Rhodoliths are autotrophic and produce energy through photosynthesis so they only survive in the photic zone where it’s shallow and light can reach the little rhodoliths.

It wouldn’t be an interesting field season with just one project going on. An interesting project that was unrelated to rhodoliths was Taylor Eddy’s project on spatial variation in spiny lobster foraging preferences. Taylor is studying how spiny lobsters interact with the intertidal habitat and the seasonal variability of these interactions. Specifically, she is looking at how different food resources available in this habitat affects their reproduction and demography (size, sex, and abundance). To do this, she collects lobsters at high tide in the intertidal and subtotal, records the size, sex, and reproductive status of each lobster, and then removes a leg (don’t worry, they grow back!) to get a muscle sample for a diet study. Taylor is a CSUMB and MLML student working on her Master’s thesis and has conducted research on Catalina numerous times. We had to collect lobsters on three transects at night from two sites (Big Fishermen’s Cove and Birdrock). The first collection night, my role was the “runner”. I shined a red light on one end of the transect while two divers (Riley Young of CSUMB and Dillon Dolinar of SDSU) collected as many lobsters as they could with their hands. We could use only red lights because lobsters don’t see the color red which was a new fact to me. Once they collected lobsters, I brought them to the boat where Taylor got her measurements.

Snails love rhodoliths!

There were two main tasks that had to be done in the lab: size frequency and core live/dead processing. To do a size-frequency, we 1) separate live rhodoliths into three different size classes 2) count the number of rhodoliths in each size class 3) measure the volume of each size class along with the dry mass of the rhodoliths once they’re entirely dry. We did the same thing with the sediment cores without separating them by size, just by live and dead ones.

Charnelle Wickliff, a student of California State University Monterey Bay and Moss Landing, has a project with the goal of measuring snail growth and movement between rhodolith beds, rocky reef, and kelp forest. This involved collecting Megastraea sp. from the rhodolith beds, measuring the width, and tagging them with a number using super glue (without gluing your fingers together). The snails were returned to the beds with markers. Charnelle will return to those markers and resample the area to find the snails and reevaluate their growth and movement between habitats.

Fun finds on a dive at Avalon! Plus a snail wanted a picture of itself!

I will definitely miss the fun times, diving, and sunsets at Catalina! Stay tuned for my next blog post on the next chapter of my internship: AAUS Scientific Diving Course!

Under the Sea – REEF [3]

A hulking mass loomed in the deep blue water, far away but not enough to escape the limited visibility. I only noticed it because the instructor, Jason, had motioned excitedly to our group, pointing off in the distance a couple moments before. It generally takes a lot for the instructors at Key Dives to get that excited underwater, so I figured it had to be something great. Sure enough, I soon realized that I was looking at none other than a pair of Goliath Groupers. One would be forgiven for mistaking these colossal fish for submarines cruising through the deep tropical waters. Words cannot describe how small I felt for a moment, witnessing these groupers go about their day around me, inching closer as we hovered transfixed. I had long known about this species but never really understood how awesome it would be to see them in person. While they are not the longest fish I have seen, their sheer weight and size is what makes them mind-boggling. I did not snap any photos because I was taking on a supervisory role that dive (to say nothing of how I forgot my GoPro on the boat), but I will savor the memory forever. All the more exciting was that this sighting occurred while diving the wreck of the Eagle. A Dutch ship built in 1962 that went on to change hands between owners in Israel and the Cayman Islands, it was struck by an electrical fire in 1985 and purchased by Monroe County in the Keys (read more here). Like several wrecks in the Keys, the Eagle was intentionally sunk to transform it into an artificial reef. These reef-wrecks are a huge draw for tourism, and part of the reason I am able to find such fantastic diving in the Florida Keys. We saw these particular goliath groupers after falling, scuba-style, through a huge hole in the side of the Eagle. Since the Eagle rests on its side, this meant positioning carefully over the hole, exhaling, and letting gravity do the work as we descended straight through the wreck, bottoming out near 100 feet deep over the sand.

I found myself on that unbelievable dive of the Eagle while completing my deep dive scenario for divemaster training. I have not touched all that much on the pure diving aspect of my summer so far in these blogs, and here I wanted to highlight that. For the record, I do not have any photos from my divemaster training since often I am supervising other divers and need to keep my focus on them. For that reason, I have peppered photos from various other dives this past month throughout the post to give an idea of what I have seen in the water! Anyway, for the first several weeks at REEF, all of my diving consisted of fish surveys, from boats run by several different dive shops throughout Key Largo. I wanted to start off slow, because prior to arrival, my only dives since Bonaire (Fall 2017) had been a couple quarry dives in Kentucky last year. While I arrived as a certified Rescue diver and was a very confident diver leaving Bonaire, it had been a long time and I knew I was taking on a big commitment by aiming to complete my divemaster as a REEF intern. I wanted to respect my upcoming training as the considerable challenge I knew it would be, and so I first spent some time in the water getting my “sea legs” back. Being able to brush up on my tropical fish identification while doing so was all the better. By the time I finally arrived at Key Dives (a dive shop in Islamorada, south of Key Largo) in late June to start my training, I felt ready. I knew that this summer I would need to become a much improved diver and educator within a very short amount of time, and I wanted to hit the ground running.

The four weeks since starting that adventure have made this the summer of a lifetime. My training started out simple with a lot of pool work, mostly knocking out water skills as well as my scuba skills circuit. I have been doing my training alongside another man named Kent, who has been nothing but helpful and supportive as we progressed along. My first experience with the skill circuit was in a nice heated pool at Mike’s house, the owner of Key Dives. I realized then how tightknit the staff at the shop was, both by how willing Mike was to open up his house for me and Kent, but also the fact that Cortney, one of the instructors, offered to come over after hours to help us. I won’t lie: I totally failed that first circuit, but I came out of the pool happy as could be. I knew before even starting that I was not going to have all of my skills down because it had been a while since doing some of them, and to pass the circuit you have to successfully demonstrate all 24 skills relevant to teaching new divers. That said, I only failed a handful of skills, so I knew exactly what to work on going forward. Within a week or so, I had finished the circuit to demonstration quality!

Diving with the other interns at BHB

With the circuit complete, I was now entrusted to demonstrate skills to divers training to get their Open Water certification. And so a few weekends ago, I worked with a father and his young son to get the son certified, and I was able to see him nearly all the way through his open water course, from pool work to checkout dives in a local marina. It was incredibly fulfilling to see the light turn on for the student as he grasped the concept of letting go and breathing through a regulator, and seeing what it was like to glide underwater in the way only scuba diving allows. These checkout dives were in a pretty unique spot too – since seas were rough that day, we dove in Jules’ Undersea Lodge. Jules’ is a local attraction nestled in a marina far from any wave action, and is in fact the only underwater hotel in the United States. Tenants stay the night by diving down about 25 feet and are greeted by a transfixing display of schooling fish attracted by the shelter of the mangroves. At the bottom is a fully furnished hotel room, complete with food and drink brought down to you. While we didn’t get to stay the night ourselves, being able to take our time and see the benthic community was a great time, for both the student and myself.

The only undersea hotel in the United States!

The visibility at Jules’ was less than stellar however, which reminded of my own open water checkout dives done in the summer of 2017 in Falling Rock Park, a quarry in Kentucky. There is something special about learning to dive in such an environment because any stray movements can kick up silt that obscures visibility, from hours to entire days. Being forced to treat the benthic environment with care is a huge benefit for those so new to diving, something that, for me at least, carried over into my dives I would end up doing in warmer waters. Diving here in the tropics is generally very easy – the water is clear and warm, and visibility only gets low when there is a rare strong current, or if you are diving deep areas like wrecks. But carrying over that level of care for the substrate below is just as important here – you never know if your next fin kick could stunt years of growth on a head of coral!

Back to divemaster, though: after successfully assisting with the training of the open water student, it was time to lead a few dives myself. I previously co-led scientific research dives in Bonaire, but that was on a dive site I knew by heart, and with an experienced buddy that I was very familiar with. Last Friday on the boat with Key Dives, I was tasked with leading a group of three that I had never met and had varying levels of dive experience, out on a site that I had never dived before. The dive briefing itself went very well, however I knew the biggest challenge would simply be navigating an unfamiliar site. After getting dropped at a site with a ripping current and no reef in sight, captain Kenny re-positioned the boat nearby. This time went as smoothly as I could have hoped – I looped in and out of a beautiful patch of spur and groove reef, always aware of where the boat was above me. It was a liberating feeling, knowing that I could do this, and it was gratifying to see the group I was leading having a blast and filming video of sharks and turtles around us.

Flying gurnard (Dactylopterus volitans) – I was very excited to see one of these fish at BHB!

With a large chunk of my divemaster training behind me now, I have been able to take a breather for a bit and hop in the water for some fun dives. I was very happy to carve out time to dive with Michael, the current OWUSS NPS intern, on Blue Heron Bridge (BHB) in West Palm Beach. Thus, we have continued the time-honored tradition of the NPS and REEF interns meeting up over the summer! Michael has been staying near Biscayne National Park for the better part of July, and we were able to make our schedules match. Over the course of two weekends, Michael, myself, and all the other interns/lead interns at REEF dove BHB together. BHB is regarded as some of the best shore diving in the world, and I must say it was my favorite experience diving so far. I gained an intense appreciation for just how impactful macro photography can be, watching Stacey and Michael spend 30 minutes at a time photographing a pair of frogfish. While I am currently only equipped with an older GoPro, I used that time to really search for the smaller things in the substrate, and was completely blown away by the sheer diversity of life found at BHB. One moment I was watching a frogfish waddle along the sand, and another I was catching a fleeting glimpse of an uncommon blenny species as it darted into an old car rim.

Our BHB dives ended up both being almost two hours long, since the site is so shallow and air lasts for a long time at ten feet. Given the time to relax and study one spot for hours, I would say that was the most content I have ever been on a dive. When Michael and Stacey shared their photos with everyone above-water, I felt as if I had missed an entire level of detail present at the site. Crisp underwater macrophotography tells a story unlike any other: the subtle markings on certain fish become apparent, the shape of the eyes suddenly becomes entrancing, the coloration of the skin gains depth. The dedication that Michael brings to the NPS internship through his photography is hard to miss, and it was in fact part of what inspired me to recently purchase an underwater camera myself! I have featured photos by him and Stacey from Blue Heron Bridge throughout this post, to provide an idea of what I have been seeing the past few weeks.

With some fun dives out of the way, I will be finishing up my divemaster here over the next few weeks, but not before a second round of Ocean Explorer’s summer camp! I am very excited to oversee another group of campers as they learn about the underwater world of the Florida Keys. Since my time at REEF is coming to a close soon, I am also finishing up a few long-term projects related to REEF’s Volunteer Fish Survey Project. Stay tuned to hear more on that front!

Behind the scenes of dive safety: Hyperbaric chambers and cylinders

“The bends” — or decompression sickness (DCS) — can be a serious dive-related injury that results from inadequate elimination of accumulated inert gases (like nitrogen) from body tissues. The body absorbs more gas from breathing while diving than it does at the surface in attempt to equilibrize gas concentrations in tissue with the increasing ambient pressure of the surroundings. Therefore, to reverse this process and eliminate the accumulated gas, the reduction in ambient pressure must be slow and controlled. For this reason, it is recommended that divers do not exceed an ascent rate of 30 feet/9 meters per minute and they perform a safety stop to wash out as much remaining gas that was accumulated under pressure as possible. In the event of a rapid ascent, inert gases are not properly washed out from the body tissues and the person becomes “bent.”

If a person is suspected to have DCS, they will be sent to the nearest medical facility to be evaluated by a physician, and then DAN will contact the nearest available hyperbaric facility for treatment.

A common misconception about hyperbaric treatment of DCS is that it causes bubbled nitrogen in the body to re-dissolve back into the blood. The real benefit to hyperbaric treatment is that the act of breathing oxygen at increased pressure and concentration creates a pressure gradient. This gradient allows for more effective removal of other gases in the body (like nitrogen) through exhalation and addresses the inflammatory response to aid in healing as well. Hyperbaric medicine is not just for scuba divers, because the benefits of high concentrations of oxygen can be used to treat serious infections and heal wounds resulting from diabetes or radiation treatment, as well as treat other indicated conditions.

Since the invention of the heart and lung machine (at the same time as the chamber was finished), this is no longer needed.

 

 

 

Duke’s hyperbaric medical facility has an interconnected multi-place chamber system, and recently the other DAN interns and I received a tour of the facility from Eric Schinazi, a hyperbaric chamber specialist at Duke. He shared with us the history of the chambers, how they were built, how they’re controlled, and how air is compressed.

The control panel station for all the chambers at Duke. Pressure gauges are visible (large round circles) and are very similar to the pressure gauge on scuba cylinders.

While we were touring the chamber, there was a research project being conducted on oxygen toxicity. We got to peek into the research chamber to see how the research subject was preparing to exercise while breathing compressed gas in the chamber.

Looking into the small pool in the research chamber. The research subject is preparing to exercise on a bike sitting under the water. He is connected to various sets of electrodes and a respirometer for monitoring outside the chamber.

A big thanks to Eric for such a wonderful tour! I hope to stay out of hyperbaric chambers during my diving career, but it was a great experience to learn what hyperbaric treatment involves.

Cylinders:

Speaking of compressed gas, last week DAN employees and interns also had the opportunity to visit the Luxfer aluminum cylinder manufacturer where we learned how the cylinders are made and tested — it was like an episode of “How It’s Made”!

Cylinders are created from one piece of metal and formed into their shape through heating and pressure manipulations. Pictures were not allowed in the factory, so to get an idea of what the process looked like, you can check out this YouTube video of steel cylinders being created. It is generally the same process, except for minor differences between steel and aluminum cylinder production and details unique to each processing factory.

A ruptured cylinder. Cylinders are designed to split like this in the event of an explosion, to avoid fragmenting and shrapnel. This proves how essential it is to take good care of gear.

While at the facility, we also had the opportunity to take a visual cylinder inspection course from Mark Gresham, CEO of PSI-PCI (Professional Scuba/Cylinder Inspectors).

All cylinders need to have a visual inspection at least once per year (and hydrostatic testing every 5 years), but visual inspections should be done more often if there is reason to believe the cylinder may have sustained damage. This could be from dropping a cylinder, running the cylinder dry (because this greatly increases the risk of water getting into the cylinder), heat exposure, or after it’s been stored for a long period of time. In the event of an explosion, cylinders are designed to split down the middle (photo to the left) to avoid fragmenting and shrapnel.

Mark also was very generous to meet with us at DAN earlier this week to continue educating us on Oxygen cleaning and cylinder valve inspection. I took my first valve apart, and then put it back together! Let’s hope it still works!

 

A special thanks to Mark for his generous time and for sharing loads of knowledge with us.

I am very thankful to this opportunity from OWUSS and DAN to gain so much exposure to all the different fields that play a role in making diving functional and safe, as well as the opportunity to learn from people at the top of their fields.

This week underwater:

“Stop polluting our water!”—A message from the fish.

Dive Safety Ins and Outs

The one word that perfectly describes the past few weeks would be exploration. In all different meanings: mental exploration and physical exploration. Now that I am back in California in between research trips, I’ve had the chance to explore terrestrial and marine environments of the local area. The day after the Mexico trip, I saw some Redwoods up close for the first time. There were so many people of different backgrounds enjoying the park and the educational trail guides. Parks are great protected lands that improve water quality, provide vegetative buffers to development, produce habitat for wildlife, and provide a place for children and families to connect with nature. It made me think of ways to get people to connect with the ocean like they do with forests. Engaging people from a variety of genders, ethnicities, sexual orientations, perspectives, backgrounds, areas of expertise, religions, cultures, and other variables to connect with nature and science is so important and this small exploration allowed me to really dig deep in thought about the availability of the ocean life to diverse groups of people. This was a great experience out of the water and a fun break before diving into more dive-related activities in Moss Landing.

I am so lucky that I get to learn about not only research diving techniques, but also about dive safety, gear maintenance, and dive planning. I shadowed the Assistant Dive Safety Officer at Moss Landing Marine Labs, Shelby Penn, for a few days and got to learn and help on various tasks. On the first day, tasks consisted of reorganizing tank records that Moss Landing keeps and I learned about tumbling tanks, hydrostatic testing, and much more. The second day, Shelby showed me how to visually inspect tanks and all the workings inside the valve. We inspected a few tanks after emptying them, by inspecting the inside for rust and bumps, cleaning out the tank, switching some new parts for the valve, and cleaning the valve. I can now say with confidence that I can put a valve back together!

On the last day, we did maintenance on some Oxygen Kits at Marine Operations and added in new gear, replaced some old parts, and updated the records. This taught me more about the proper gear to keep in oxygen kits and made me more familiar with these important safety tools. Now I know exactly what goes into emergency O2 first aid, as well as other first aid techniques I learned in DAN’s Diving First Aid for Dive Professionals (DFA Pro) course that I took at the beginning of the internship.

Besides learning about dive safety, I got to assist a Moss Landing graduate student, Max Rintoul, with his thesis project focused on kelp growth at Granite Canyon with another Moss Student, Dan Gossard. I learned more and more about the history of MLML  and several grad students’ experiences. From how they created their research project, worked through stages of revisions with their advisor and mentors, actually going out in the field (or lab) to observe or conduct experiments, and finally working through samples/data to answer their research question.

Moss Landing Marine Laboratories administers the Master of Science in marine science program for California State Universities in northern and central California and is dedicated to both education and research. It is so great to meet graduate students who work at Moss Landing but are from different California State Universities. I love the collaboration between the students and faculty, between lab members, and between different labs entirely. When you’re a scientist, one of the best parts of the job is getting to work with other scientists. It’s sharing your ideas with other people and together creating the best science that you can. I am super excited to work with more scientists especially since I am going to Catalina Island in a few days to help with multiple Rhodolith projects! More on that next time!

Summer Camp Round Two – REEF [2]

Sunset view of the palm trees swaying in the wind at La Jolla Resort

Summer camp was always a special experience for me as a kid. Growing up, camp was a time for me to escape from the confines of the classroom and explore new possibilities during summer breaks. My parents were great and exposed me to plenty of different kinds of camps, my favorite being one that was held on a sprawling farm called Pepperhill in the backcountry of Kentucky. I begged my parents to sign me up again, year after year, because there was something so reassuring about knowing I had untold adventures awaiting for me every summer. Whether it was horseback riding, gaining experience levels in the pool, shooting archery, or going on caving trips, summers on Pepperhill developed interests for me that I never would have had otherwise. Camp took an already burgeoning personal interest in the outdoors and developed it into a burning curiosity for what lied in store for me, essentially in my backyard.

You may be wondering why I am talking about a camp back in Kentucky on a blog post about REEF and the underwater world. Which is reasonable. I say all this because I see no better way of prefacing why contributing to REEF’s Ocean Explorers Camp was so meaningful for me. A few weeks ago I met 15 campers on a Monday morning, bright and early. We were stationed under a small structure called Grouper Pavilion in John Pennekamp Coral Reef State Park, going through the stages of trying to remember everyone’s names. The first few campers that I interacted with under the pavilion only took interest in me because I sat down at the crafts table and started sketching a (terribly depicted) tropical fish. I did not expect them to be so excited to join in, but soon they were producing drawings way better than mine! Keep in mind these were 3rd graders (the ages of campers ranged up to about 8th grade). I had no idea what I was getting into, to be honest, since I had never acted in this kind of capacity with kids so young before. The closest I had come was helping run a live touch tank in Charleston last summer, but being an actual camp counselor this time around brought with it more responsibilities. I did my best to hang back and let the kids enjoy their activities on the first day, and watched to see how Brittany, our supervisor, handled the kids’ endless questions. I wanted to make sure that I was being a good role model, especially since this was Ocean Explorers Camp – what these kids learned about the ocean during their week with us could truly make a lasting impression. That said, my first day mostly consisted of supervising kayaking and snorkeling activities, so my job was mainly to keep kids from absconding into the mangroves.

Over the next couple of days at Pennekamp we spent time out on the reef, via glass bottom boat and a snorkeling charter. I learned that there is truly no better way to distract children than by sticking them on a boat where they can look down and see the ocean. Several large nurse sharks and barracudas swam by under the boat, serving to both entrance the kids and provide us interns a much needed break from constantly wrangling runaway children. This was also around the time when a girl named Dakota became particularly enamored with stealing my sunglasses (and occasionally my buff). She and a couple of her friends were actually the same campers who outdrew my feeble attempt at a fish on the first day of camp. I am not sure what was so special about my personal belongings, but she was so proud of wearing them out on the boat that eventually I gave up and let her do her thing.

The kids couldn’t keep their eyes off the reef. Nothing like a couple nurse sharks to keep them occupied

On Thursday, we went back out on the boat, but this time the kids got to jump in the water and see the reef up close. Our boat stopped near the locally famous Christ of the Abyss Statue, which has a neat history, as a Pennekamp Park Ranger told us. It was one of a set of three Christ statues sunk around the world, this one sunk in Dry Rocks reef off Key Largo in 1965. The first two were sunk in Italy and in Grenada, to commemorate a fallen diver and as a gift to the people of St. George’s, respectively. I had never visited this renowned site, and I was just as excited as the kids to snorkel around the statue. Making sure the group didn’t stray too far from the boat was a bit stressful, but if anything it was good preparation for my divemaster training this summer! After a nice day out on the water, we enjoyed a relaxing boat ride back to the mainland, where the kids got to witness a pod of dolphins frolicking through the water.

Heading back from snorkeling, the captain sighted a pod of dolphins. Here the kids looked on as we circled back around

And so the final day of camp arrived. On a second kayak trip out to the mangroves, my boat partner was none other than Dakota, the sunglasses-snatcher. She asked if I would be back next year, and I had to tell her maybe, but that I would probably be elsewhere. I could tell she really enjoyed being at camp and didn’t want to leave – a very sweet moment. Near the end of the day when the campers got to visit the gift shop, she ended up spending a decent chunk of her money on a pair of sunglasses and a buff, so she could look “just like Mr. Ben.” I honestly had to keep it together a little bit when she said that, and I knew it was going to be hard to say goodbye to this group. Around this time, I also got to spend more time with the other half of the group I had not interacted with as much throughout the week. They were a bit older than the others, and were genuinely interested in hearing what I had to say about identifying all the different fish in Pennekamp’s mini-aquarium. Gaining experience interpreting facts about tropical marine conservation to an age group I wasn’t used to was a huge plus for me during Ocean Explorers camp.

The group learning how to make “slime” (a mixture of water and flour). The slime represented slimy materials that marine fish use all the time, from mucus coating the bodies of moray eels to bubbles that parrotfish sleep in at night

At the end of the day Friday, the campers were tasked with making their own collages using photo prints from the past week. Dakota refused to leave without giving me hers, one that she had put a lot of work into, and my heart melted a little bit more. I realized then that I saw myself in these campers. When I was that age, positive experiences where I could really dive into a new environment were so important, and it was special to be on the other side this time as a counselor. I have actually gone ahead and signed up to help out with another summer camp at the end of the summer, as a nice send-off from my time at REEF.

Aside from summer camp, another huge aspect of REEF’s outreach during the summer are lionfish derbies. My first derby was right after summer camp week, which was a pretty dramatic turnaround. Just after the last camper departed on Friday, we grabbed our dive gear and headed up to Ft Lauderdale for the weekend. Friday night we took it easy and met up with Alli and Moose, the staff members that head the Invasive Species Program at REEF. Early Saturday morning, we headed over to Sea Experience dive shop to help set up for the day’s lionfish dive. At the shop, Alli presented about lionfish, explaining to participants how lionfish invaded the Atlantic, how lionfish have devastated native fish populations, and how we can help fend off the invasion. Many of the participants were fishermen, who were very gung-ho about getting in the water and spearing some invasive fish!

After weathering a very rainy and overcast morning, we set out for our afternoon lionfish dives. This would be my first time spearfishing, as well as my first time participating in a drift dive. I was nervous, but very excited to be out on the boat and gaining new experiences. As we approached the dive site about 5 miles off the coast of Ft Lauderdale, the Miami skyline greeted us through a post-rain glow. Giant striding into the ocean with that scenery around me was surreal, and it only got more exciting as we descended to ~80 feet. The ocean floor was very different than what I was used to on the reefs surrounding the Keys – some of the same fish and coral species were scattered across the bottom, but the terrain was flat and unforgiving. Additionally, the concept of having to let the current take me where it pleased was humbling. Not so humbling, however, was being able to spear my first lionfish. I missed the first couple tries and was fairly disheartened, but kept at it and was able to get a great shot into a sizeable fish. Lionfish are so unused to being predated in the Atlantic that it was hardly a hunt at all, but nevertheless I felt a rush of excitement. I was suddenly reminded of why diving is so rewarding for me – there is nothing quite like being able to explore and contribute to scientific efforts. It never hurts to be carrying a spear underwater either.

On Sunday, the festivities really began with the Ft Lauderdale Derby. Thirty total divers brought in 417 invasive lionfish (you can read more about that here)! As part of the team helping measure each catch, this meant I was chucking hundreds of lionfish up onto a table for Moose to process. Team members looked on eagerly to see if they brought in the biggest fish, since there were awards for biggest/smallest catches, as well as most fish caught. The biggest catch ended up being 392 mm, or about 1.3 feet! The event was a whirlwind of activity, but it was a great chance to see citizen science in action. Each catch and its measurements were logged, which will help contribute to an ongoing project to see how many lionfish are present off the coasts of Florida. A large part of why I was excited to take this internship was the ability to help out with events that truly engage the local community, and this was a perfect example of that. I am very much looking forward to the Sarasota Derby being held at Mote Marine Laboratory this coming weekend.

It is strange to think I only have about a month left as a REEF intern – there are so many projects going on here, a few of which I will center my upcoming blog posts about. Of particular interest to me is the Volunteer Fish Survey Project, which I am planning on committing much of my time to in the next several weeks. I am also hoping to team up with Michael, the current National Parks Service Intern, for a day, so stay tuned for that. I would also recommend reading his excellent post about Isle Royale National Park!

Lastly, below are some stray photos from fish survey dives I have been doing while not corralling kids or spearing lionfish:

My favorite photo I have taken so far, albeit without any color correction. I love seeing healthy Acropora palmata (elkhorn coral) out on the reefs, as that can be few and far between now in the Keys. Coral Restoration Foundation is doing great things to help restore this species – I hope to volunteer with them soon!
