Washington Department of Fish and Wildlife (WDFW) 

A unique opportunity to go out on the WDFW law enforcement boat was a great insight into how science and public safety collide. Seeing how organised and structured their dive operation was, was inspiring. We saw a pod of orcas from the boat containing two fully grown males whose fins stood proudly tall above the water line for many moments before sinking below the untouched surface. It was such a magical experience. After they finished their dive to collect sea cucumbers, I got to help them with taking length measurements which involved splitting them open and pulling their insides out. This was an odd experience since at depth they seem so tough but when you open them on land and release the water pressure they are really just fleshy moulds. We then weighed their gonads which became a part of a larger dataset that will inform them of whether to change the dates of the fishery.

Samish Indian Nation Dive Team 

Another project I had a more hands-on role for was a collaborative effort to pick up artificial reef module systems (ARMS) which had been laid down a year prior. They are essentially mini apartment buildings for organisms which was an amusing site. The task of recovering these ARMS was a 2 day event. The first day I went out with the Samish Indian Nation dive team in order to do recon and get a good idea of where exactly they were laying after being in the field for a year. This was my first ocean dive in Washington. I had anticipated the cold, but nothing prepared me for my first breath after my head was submerged. I’ll never forget the sound of the ice cold water seeping into my wetsuit hood… which quickly became one of my favourite sounds ever after I fell in love with the kelp thickets, sea lions, and cold water reefs that Washington has to offer. What a great introduction to PNW diving! The second dive day was to consist of actually rigging and lifting the ARMS out of the water. This, however, did not go exactly to plan. There were strong currents and my fellow divers were newly certified from the dive program at SPMC and as such didn’t have the experience to handle these conditions yet. We gave it our best shot but in the end had to call the dives and return to shore. This was the first of many times this summer that I learned that science doesn’t always go to plan. (a WDFW team returned a few days later and were able to retrieve them). 

Proficiency Dives 

SPMC is lucky enough to be in close proximity to Walla Walla University’s Rosario Beach Marine Lab where Dr. Allan Verde and Dr. Jim Nestler conduct their scientific diving program. I teamed up with them and a couple of their students to go on proficiency dives most weekends. This experience gave me the opportunity to dive at Keystone which is a unique shore diving site next to a ferry terminal, known for its abundant marine life including giant plumose anemones, diverse nudibranch species, and even plentiful octopus gardens. This is by far my favourite dive site of all time. I dove there often with Tabi from the State Park Service and Joe from NOAA who are such knowledgeable and skilled divers. I learned a lot from these proficiency dives such as how to read tide and current tables and to determine if conditions are safe to dive at a site. I learned to slow down while diving and peek into every crevice because you never know when 2 little eyes might be poking out at you belonging to the elusive giant pacific octopus (GPO). I had read all about them before diving there and was desperately excited at the prospect of finally seeing one, since I had been dreaming about them ever since I was a little girl… but to actually see one in person was like nothing I’ve ever experienced before. I was truly and totally enthralled by it. I sat in front of one den for half of a dive and only swam away because I reached my turn around pressure. I could have watched it for hours; the way its tentacles unraveled and its siphon periodically swayed open and closed, they’re incredibly rhythmic and mystical creatures. After each dive I felt I surfaced with more questions about them and it would keep me returning each week even when I had to wake up at 4am to make the slack tide.

Sessile Jellyfish Research with Nate 

The DSO at SPMC took me and the other OWUSS intern (Caden Delano) to Possession Point State Park on South Whidbey Island where we were looking for Aurelia sp. Jellyfish polyps in their sessile phase as a part of Nate’s personal research. This dive site was unique in 2 ways: firstly, it was a beach where you are stood in 7ft of water and then suddenly it drops off to almost 300ft of water almost immediately; secondly, it was an estuarine environment meaning that it was not rocky (as most of Washington’s coastline is) but sandy. Unfortunately this dive was another lesson in how science doesn’t always go to plan because we were unable to locate the polyps. However, I had a truly magical experience at the start of the dive as well as 50ft of visibility (unheard of in Washington) which made the trip worthwhile. As we completed our buddy checks on the surface, I heard the unmistakable sound of a large mammal’s blowhole… I paused midway through checking my BCD deflator and dumps to see the tail of a humpback whale descend gracefully not far from where we were. We completed buddy checks and remained on the surface for an additional couple of minutes to watch as the whale surfaced another few times. Our slack tide timings were specific however, and it was time to descend. As the familiar woosh of cold water seeping into my wetsuit hood hit my ears, it was drowned by another, unfamiliar sound. We all looked at each other confused for a second before our eyes lit up in turn as we realised it was the sound of the humpback emanating throughout the water column. As it continued to sing I breathed in the moment and noted how its tone was simultaneously high pitched and deep; a sound I could never re-create with my human vocal chords.

Abalone restoration 

SPMC hosts a number of Research Experience for Undergraduate (REU) students each summer in addition to the 2 OWUSS interns, a couple of whom were a part of the scientific dive class and subsequently conducted an underwater research project which I was able to be a part of. We collaborated with Puget Sound Restoration Fund (PSRF) who gave us almost 800 pinto abalone to experiment on and outplant, as well as funding to complete our research. 

Pinto abalone (Haliotis kamtschatkana) populations remain critically low despite ongoing restoration efforts. To improve outplanting success, we tested the effectiveness of clear and opaque tubes on abalone dispersal rates and evaluated the predatory behavior of Amphissa columbiana toward healthy and injured abalone. In field trials, clear tubes resulted in significantly faster dispersal rates than opaque tubes, suggesting that increased light exposure may encourage abalone to leave the tubes more quickly and integrate into the natural habitat, potentially improving survival. Laboratory choice experiments showed that A. columbiana did not actively prey on healthy abalone, but significantly preferred injured individuals. This highlights the importance of minimizing injury during handling and transport. These findings suggest that the use of clear tubes and gentle handling protocols may enhance the effectiveness of current abalone restoration strategies. Further research is recommended to explore the benefits of nighttime outplanting, alternative tube anchoring methods, and predator exclusion during outplanting to support long-term recovery of this threatened species. 

The field trials mentioned were conducted as a 24 hour dive protocol. We had a team of 12 divers who took it in shifts to count and observe the movements of the pinto abalone out of the tubes every hour on the hour for 24 hours. This dive expedition brought many challenges with it including how to keep people safely warm, fed, and dry between shifts as well as how to account for varying ocean conditions over a 24 hour period. As such, it was a great experience to plan such a dive because it gave me an excellent insight into everything which must be accounted for when you are leading a dive, like I’ve never experienced before.

Rockfish surveys 

A researcher at SPMC was conducting rockfish surveys on what their depth and size is throughout the San Juan Islands as a part of a very large dataset on them. I had the opportunity to dive with her on a multilevel dive to collect length and depth data in the local area nearby Rosario Beach. This was a great way to connect with other scientific divers at SPMC and emphasised the vastness of what can be researched in the ocean since it was so different to everything else I had done so far. 

GPO collection dive 

A local aquarium required SPMC divers to collect a GPO for their exhibit which had recently lost its resident GPO. This dive required a lot of planning and was another example of how science cannot always work in our favour – sometimes the ocean has other ideas and we, as humans, must respect that. Myself and a small group of divers had planned this dive thoroughly, gathered all of the necessary materials including multiple nets, fresh water in bottles to wash the GPO out, a knife to open up a clam underwater as an offering to the GPO, as well as the exact location of the GPO in a tire reef (as shown in the image), conditions were as calm as we could have ever hoped for, tanks were filled and we were ready. But GPOs are masters of disguise. No one can capture a GPO once it has decided it’s time to escape, they are true artists of contortion and deception. We had no chance against it in the maze of tires and had to allow the ocean to keep its mysterious creature. I left that day with a great deal more respect for the creatures which I had come to love and appreciate throughout my time in Washington. The aquarium was able to acquire a juvenile GPO from Walla Walla university which had captured one accidentally in a bottle through their research on ruby octopus earlier in the summer.

Friday Harbor Labs Lime Kiln Lighthouse 

A visit to Friday Harbor Labs brought the opportunity of diving the hydrophone site at Lime Kiln Lighthouse about. We followed the thick cables down from the rather dicey shore entry to where the hydrophones lay and pick up everything from orca vocalisations to ship disturbances to myself and Caden singing a rather bubbly rendition of “Under the Sea” from The Little Mermaid whilst on our dive. Our mission for this dive was to take a video recording of both hydrophones and cables as monitoring; since no one had been down to check on them in a while. Through talking to the hydrophone lab manager, I learned that they are working to reduce vessel speeds in many areas in order to reduce decibel levels which when too high, can interfere with vital whale communication.

Lily Moore Blog Post #1

Helping with the Shannon Point Marine Center scientific diving class taught me three main things: always discuss the dive plan in-depth before descending, never underestimate a student’s ability to lose their dive equipment, and that science is the best when you’re wearing neoprene. Whilst I have worked as a recreational divemaster, assisting with a science dive class was a totally different experience because it demands so much more of the students. I was paired with the newer divers to work on helping them feel comfortable doing their basic skills in the pool. It was a good experience to have to employ different methods of empathy, sincerity, and firm instruction in order to reach each person on their level and get them to do their skills with a smile on their face. Each day came with its own challenges but the supportive atmosphere of the class remained the same each day. My favourite thing to observe was when there was a student who was confused about how to do the BCD remove and replace skill underwater and another student who had just mastered it remained on that skill with him and kept giving tips and tricks until he could not only do it but felt confident doing it.

The first open-water dive was at a lake, and as a simple introduction to science diving we did a trash cleanup. We found some very exciting objects such as a wallet with a $100 bill in it which just so happened to belong to a friend of one of the students in the class… you never know what may wash up. This day I learned the power of team work when it comes to the success of a dive. Some students were quite nervous about the dive and the ones who worked together to discuss their concerns ended up having a great time and ones who didn’t vocalise their concerns didn’t have as positive of an experience. After this, I began to go around each student individually at some point before the dive to make sure they didn’t have any concerns/questions. Not only did this help them feel more comfortable and make the dive objective easier to achieve but it also allowed for me to have a more personal interaction with them. As such, assisting with the class helped me develop my dive leadership skills.

A big part of my role in the dive class was to assist the DSOs with their prep and cleanup pre and post dives. I had no idea that there was so much behind the scenes work which had to be done to make a dive class run smoothly. We had to plan the dive locations based on the current and tide tables, as well as planning all of the equipment and tasks for the divers to complete, all of which needed to be done efficiently and safely. Through working in the dive locker I learned a lot about equipment handling. I assisted with tank visual inspections and performed simple gear maintenance tasks which taught me how to fix many common gear related issues and developed my general troubleshooting skills. After the class the DSOs and I spent many hours running tanks to and from the local dive shop to be filled which provided an insight into the true life of a DSO and allowed me some time to ask questions of them. In this time I learned how hard it is to manage a dive class and the stresses which come with such responsibility, in addition to the joy and enthralling stories which being in the ocean every day provides.

Whilst helping with the dive class was an overall joyful experience, it did come with some unique challenges. There was a day where we were doing a deep dive followed by a night dive and when we arrived at the deep dive location there was significant swell which meant we couldn’t put the bow door down of our front loading vessel and it made everyone feel seasick. Luckily, my sea legs were on that day and by some stroke of magic I was the only one who didn’t get seasick. As such, I found myself untangling weight belts, lifting gear setups onto people’s backs, coaching people through deep breaths, and putting on 12 sets of fins to prevent people from having to bend over while at their worst. That was challenging enough not to mention that 5 students had never done a back roll entry before, so in this swell I counted down “3… 2… 1” and with a slight push here and there, they all did it. The visibility on that dive was so bad that I was incredibly grateful for my dive light since once we hit 80ft it was essentially a night dive. Following that, the actual night dive was hilarious. It was what can only be described as “The Shrimpening”, the photo says more than I can with words but it was like swimming through pure shrimp. There were also a number of dives where I felt the true power of the ocean in the form of strong currents. Coming from Florida, I had never really experienced anything as intense as these tidal changeovers. As such, being a leader in this class helped me to gain a lot of experience in varying dive conditions and to learn the extent of my limits as a diver.

Overall, helping with the dive class helped me become a more confident diver in harsher conditions and allowed me to develop my skills as a dive leader. But most importantly, to learn how to lift other divers up and make some lifelong friends.
