New Adventures Start Here.

While in Maine opportunities come both under and above the surface. When I’m not diving, I have the chance to explore the state of Maine. This past weekend I decided to venture north and explore Acadia National Park. One fun fact about me is I am an avid road cyclist, so much so I had to bring my bike to Maine for the summer. So, when briefly researching Acadia and what to do over the weekend, I read about the carriage roads. These roads were commissioned by John D. Rockefeller from 1913 to 1940. These 57 miles of compacted smooth gravel roads are perfect for runners, walkers, bikers, and even the occasional horse-drawn carriage. My weekend was filled with numerous miles on my bike exploring the trails and taking in all the beauty that Acadia had to offer. The highlight of the trip was climbing to the peak of Cadillac Mountain which had spectacular views of the coast and Bar Harbor.

After the great weekend, it was back to work. Doug had signed Courtney, a summer intern at Bigelow also working in the lab, and myself up for a boating course. In the event one of us needed to drive the boat we would have the proper training and knowledge of the high seas. The class was two days and consisted of learning the entire US Coast Guard “Navigation Rules and Regulations Handbook,” survival procedures for cold water environments, a multitude of anchoring methods, and how to read and plot on charts.

After the two days of the boating course, I had my AAUS class at the Darling Marine Center. Before each class, we have designated reading material from either PADI or SDI. Our class time is spent reviewing these readings and Chris Rigaud usually gives a quick PowerPoint lecture on this week’s scientific diving skill. This week class was short due to the high tide coming in at 11:15 a.m. Here in Maine and especially around East Boothbay, the tides rise and fall over nine feet! Therefore, it is essential to get out during high tide when we have the most water. We had two dives planned in which we would be reviewing our navigation and buoyancy skills, along with other small tasks. Our first dive was fairly shallow at 30ft with the water temperature reaching a chilly 51oF. During our first dive, we practiced mask removal and replacement along with buddy breathing. Chris teaches a more rigorous buddy breathing than in normal SCUBA classes. Buddy teams must share only one regulator taking two breathes and passing it to their buddy that is holding their breath. (Well not really holding their breath because we all know the number one rule in diving — never hold your breath!) The buddy team must safely ascend using this method. After practicing these skills, we were released to plan a quick dive while floating on the surface. The only stipulation of this dive was to navigate back to the departure point.  We planned a short out and back dive along a nice kelp wall with massive kelp completely shading out the bottom. Lobsters and crabs scurried and hid as we passed just overhead.

After a one hour surface interval, we were back for our second dive. The sole purpose of this dive was to try and prefect our buoyancy and streamline our dive set up. Chris had set up two hula-hoops just big enough for a diver to squeeze through without touching the sides. In many buoyancy classes, students swim through swim rings or swim squares at fast speeds. Chris implored us to try and inch our way through, stating: “Anyone can maintain neutral buoyancy swimming Mach 3, but it takes real skill and control to go slowly through it.” The ultimate goal was to stop and hover exactly in the middle of this small hula-hoop a task I could not complete. These 25 minutes of us having fun and practicing our buoyancy is something many divers don’t give themselves. Most divers whether it be recreational, commercial, or scientific usual have some objective of the dive – exploring a reef, repairing a pipe, or sectioning the bottom. Most people do not dive just to try and work on their dive skills. I enjoyed and valued this practice time and hope to dedicate more time throughout this summer and in my life to working purely on such skills.

My first dive at Bigelow and in front of Doug and Thew was a bit anticlimactic. Due to unforeseen issues, we have yet to start collecting field data on the kelps, so this dive was primarily a check out dive for Thew and myself. Thew especially, wanted to make sure his gear was in working order and his new drysuit seals were properly trimmed. We used this dive to get oriented with each other’s equipment, weight systems, dump valves etc.. The second goal for this dive was to practice the sampling methods that I would need to carry out on a dive. The dive was short, around 20 minutes at 20 feet. The sampling method had us run out a 25 meters transect line on the bottom. Using the half meter quadrats I made, I would start at the beginning of the tape measure and lay my transect on the bottom. Any kelp stipe (the root) originating in the half meter transect was to be cut and put in the collection bag I carried with me. I would replicate this process four times – at the 2,4,6, and 8 meter mark on the meter line. The dive was successful because 1) Thew and I both gained knowledge of each others dive setups, and 2) I felt confident in the sampling procedures that I would be conducting independently on future dives.

To end the week, Bigelow had a BBQ on Friday for all of the employees and interns. During the BBQ there were the “Lab Olympics” going on, which had different wings of the building competing against each other in different oceanographic themed challenges. The BBQ was a good way to meet other people who worked at Bigelow and to get to know Doug and Thew on a more informal level.

Next week we start conducting our kelp surveys. Doug, Thew, Courtney, and I will be going on a three-day dive trip to Hurricane Island to do the work.

My first week: Bigelow providing big opportunities.

My name is Shane, and as the Our World Underwater Scholarship Society Dr. Lee H. Somers American Academy of Underwater Sciences 2018 intern, I have two primary goals for this summer – complete the AAUS scientific diving class, while simultaneously getting hands-on field research at Bigelow Laboratory for Ocean Sciences.

My first full week in Maine has been getting settled in and getting into a rhythm. Maine is a lot like home — Minnesota — and so the transition of settling in has been an easy one. What we do not have in Minnesota is a front row seat to the amazing and powerful Atlantic Ocean or the focus of my research: kelp!

At Bigelow, I am being mentored by Dr. Doug Rasher, a senior scientist working on collecting kelp growth data on the coast of Maine. Along with Dr. Rasher, I will be working closely with his post-doc, Thew Suskiewicz. During my first few days, Doug and Thew put me on the task of making rectangle half-meter quadrats out of PVC. This seemingly small task was nothing of the sort, as they entrusted me to accurately and thoroughly prepare five quadrats to perfect specifications. If built too large or small even by an inch, could skew the valuable data we will be collecting.

An example of the five half-meter quadrats made from PVC. Black tape lines two sides every 5cm for video analysis.

After completing the quadrats and acquiring the appropriate materials, Thew and I were simulating my job during a dive. For these first dives, I will be cutting and collecting kelp and other seaweed for biomass samples back on the surface at the lab. After gear organization and checks, sampling material and methods completed, my last task during my first week at Bigelow, was digitizing kelp cover data from the 1990s. In Excel, I would copy the site location, depth, date, and percent cover of kelp from paper records.  It’s the less glamorous side to science and scientific research but will be helpful and necessary later in the process.

Not only am I working at Bigelow, but on Wednesdays, I head up to the Darling Marine Center part of the University of Maine to take my AAUS class with Chris Rigaud, a world-class diver, and instructor. The first AAUS class was mainly orientation and fitness testing such as the 400 and 800 yard swims. We briefly entered into the surprisingly warm (55oF) salty water of the Damariscotta River. In this brief “check-out” dive we reviewed skills such as cramp removal, taking off and putting on our BCD’s, and inflating our emergency signaling devices. These seemingly simple tasks even for a relatively novice diver are important.  Chris said this about the exercise, “What separates professionals (scientific divers) from others, is they practice the small things, they practice all the little details too. That way if the time comes when they need to use that skill, they’ve done it.” He went on to say, “I’ve been lost in the ocean and it isn’t fun” in reference to when he asked us to inflate our signaling devices.

 

Suited up for the first dive practicing key skills like buoyancy and navigation. From left to right: Colby (assistant instructor), Chris (instructor), Shane (me), Nick (student), and Rachel (student).

This really stuck with me, and I’ve been thinking about it ever since. That was great advice especially at the beginning of the summer. It is the small things that can make the difference between completing an experiment correctly or having a successful safe dive. The small things can help you in a dive emergency if it arose. Attention to detail now can pay dividends later. I don’t just want to go through the motions this summer. I want to learn as much as possible and apply everything I can, even the small seemingly insignificant details. Any skill, even if I’ve learned it before, I can still get something new from the experience. This summer I am looking forward to having a lot of “firsts” but also expanding on what I already know.

Next week is diving and lots of it! Thank you to Our World Underwater Scholarship Society, American Academy of Underwater Sciences, and Bigelow Laboratory for Ocean Sciences for giving me this great opportunity.
