After my time in Beverly, I spent the second half of the week back in Woods Hole to join the NAUI Rescue course Sea Rover President Kim Malkoski was teaching at WHOI. Kim and her coworker Giorgio led lectures on the first day, and then on the second Kim and us four students dove off the dock at WHOI for the practical section. We practiced different surface towing techniques, and made sure we knew how to properly ascend while carrying another person. At the end of the dive, we stayed in the Well, a hole in the dock where divers can enter and exit from, and all took turns thrashing around and generally trying to be as uncooperative as possible to give our ‘rescuers’ as much of a challenge as possible. I had a lot of fun with that part! I’m really glad I got to join the class, and I learned a ton, so am excited to have the chance later this summer to complete my training and be Rescue certified, since I wasn’t able to join the final examination day.

Kim also walked me through a lot of dive planning techniques I hadn’t been exposed to before! We calculated my SAC (Surface Air Consumption) Rate, which describes how much air a diver breathes in a minute at the surface, which helps them calculate how long their air supply will last at depth. We also walked through several techniques of planning a dive based on different limiting factors (bottom time, air consumption, etc.) and dive profiles. I’m really glad I had the chance to learn all of this from Kim, I can already tell it’s going to come in handy in the future.

On my last evening with Kim, we stopped by her WHOI friend Emily’s house, where Emily was having a barbeque! I met a bunch more of Kim’s friends and coworkers from WHOI, tried a quahog stuffie for the first time, and bulldozed through some exquisite corn dip. I also graciously and heroically defended Kim from dying of asphyxiation by eating her portion of the mango salad (to which she is allergic).

It was so lovely to return to the Malkoski home, and I both learned a ton and had a great time. Thank you again to Kim, Vin, and the whole Malkoski crew for being so welcoming to me! I can’t wait to visit again.

Sea Rover Dave Caldwell works at the Harborcenter in Beverly, Massachusetts, and graciously invited me to come in to work with him for a few days! I learned that on top of enforcing harbor regulations and managing boat traffic, Harbormasters respond to all kinds of emergencies on the water as well. Thankfully, both my days with Dave were relatively calm and everything ran smoothly. No capsized boats on our watch!

I joined Dave for all his morning and afternoon patrols, where we drove the Harbormaster boat around the Beverly area to search for anything amiss. When Dave heard that I’d never driven a boat before, he was more than happy to show me the (metaphorical) ropes and help me understand some of the boating rules he helps enforce as a Harbormaster, like the no-wake-in-the-harbor rule. I was really excited to be able to drive a boat for the first time, and am so grateful to Dave for being so willing to teach me! I got lots of practice maneuvering through the harbor channels and between moorings, and also got to head out further all the way to Bakers Island, being careful not to get too close to any of the lobster buoys that could get tangled in the propellers. The Beverly Harborcenter has three boats they use, two larger ones for further and faster trips like this, and a smaller one for maneuvering around the harbor. I got the chance to drive all three thanks to Dave!

 

On my second and last day in Beverly, Dave invited over his friend (and friend of the Sea Rovers) Dean Julien, from the Beverly Fire Department, to give me a tour and overview of their Dive Rescue Team operations! He showed me inside the Dive Rescue truck, where the team’s dive gear is assembled and ready to be donned at a moment’s notice, and explained the process of responding to rescue dive calls. Seeing inside the truck was fascinating, but there are also so many hidden compartments around the outside of the dive truck, including a full gas compressor, dinghy, extra tanks, and gear for ice diving. Then, he took me on board the Fire Department dive boat, which was docked by the Harbormaster boat, and showed me the various firehoses and dive setups there too. Dean was incredibly kind and really thorough in his explanation of his work, I loved talking with him! I’m really grateful that Dave invited him over.

On top of his work at the Harborcenter, Dave and his wife Heather Knowles run a dive charter on their boat, the Gauntlet (more on that in a future post!) and travel the world diving in caves and mines. Both of them are accomplished tech divers, Dave himself being NAUI’s Northeast Manager, and it was absolutely incredible to hear about their diving escapades and see some of the videos they’ve made to document those dives! It’s a whole other world of diving that was really fascinating to get a glimpse of. If you want to see some of these videos, they can all be found on Heather’s YouTube account here.

Thank you so much Dave for hosting me at the Harborcenter!

On Sunday June 8, I got up at sunrise to drive down to Connecticut. Rick Simon (a Sea Rover and former Intern!) had invited me to come wreck diving with him on his boat, the R/V Integrity. Rick and Eric Takakjian (also a Sea Rover) both captain the ship, and as we loaded our gear and tanks onto the boat, I met the friends of Rick and Eric’s who would be diving with us.

We got to the wreck in plenty of time, so once we dropped our anchor we hung out for a bit on the boat. After a while it was clear that this maybe wasn’t the best site to dive that day — huge swells coming off the reef nearby were rocking the boat too much. We decided to pull up the anchor and move to a different wreck about 90 minutes away, a tugboat called the Mary Arnold.

Once we arrived, we dropped the anchor again and Mike went down after it to make sure it was secure. Once he came back with the all-clear, everyone hopped in the water. Well, everyone except for me and Rick — we couldn’t just leave the boat unattended! Once the first group resurfaced, Rick and I finished gearing up, accompanied by a fantastic selection of 70s hits courtesy of the radio playing over the speakers.

Rick and I hopped in the water, and descended along the line. I had some equalization issues during my first week with the Malkoski family, but was happy to find that I was able to equalize my ears no problem! The Mary Arnold is about 60 feet deep, and as we descended down, the wreck’s tall engine came into view. Rick and I left strobes on the line, as a way to communicate who was still on the wreck, and then set off to explore the wreck itself. 

The Mary Arnold sank in the 40s, so there’s been plenty of time for algae, sponges, and cold-water corals to encrust the pieces of the wreck. When it sank, it broke apart, so sections of the boat are strung around the area. There were lots of big fish hanging around the wreck, and we found a few lobsters hidden away as well. I even spotted a ribbon of nudibranch eggs! We started at the engine and made our way over and around to the six-foot-wide propeller (much bigger than I thought it would be!), which was covered in cold-water corals and algae that swayed in the swell. It was really exciting to see the corals, since most of my cold water dives have been shore dives at sites with more kelp or seaweed than coral. I was hovering right up close to get a good look at the coral polyps, so I didn’t realize we were looking at the propeller! Rick and I had a very funny pantomimed underwater conversation as he tried to explain to me what we were looking at.

Once we boarded the boat again, we laid all our gear out to dry on the deck and started getting ready to head back. At this point it was time for lunch, and we were all hungry. Luckily, we came prepared! We made some delicious sausages for the ride back, and I talked to Rick’s friend Eric about the group’s wreck-diving adventures and learned about how their rebreathers work.

I’d never dove off Connecticut before, nor had I done any wreck dives, so I was really excited to experience this new kind of diving, especially with Rick, who clearly loves it. I’m so glad he invited me to come along! I had a blast and can’t wait to head out with Rick and the Integrity crew again.

During my first week at WHOI with Kim, I had the opportunity to meet for an afternoon with Sea Rover Dr. Roger Hanlon at the Marine Biological Laboratory in Woods Hole. As someone who loves all things cephalopod, it was amazing to meet Dr. Hanlon and talk about his work studying cephalopod behavior! We talked especially about some of his current research into what cuttlefish camouflage actually looks like to the predators the cuttlefish is trying to fool. I learned that he met one of his research partners at the Boston Sea Rovers Clinic, and Dr. Hanlon walked me through what they’ve been working on in the past few years.

Cephalopods like cuttlefish and octopuses are in complete control of how they appear to the outside world, and are able to change their color, pattern, and texture within the blink of an eye to match their surroundings. The question Dr. Hanlon and his team are asking is what the camouflaging animal looks like to other sea creatures, since they all perceive color differently. Some (like us) have three color receptors, while others have two or four, or more! Mantis shrimp famously have twelve color receptors in their eyes, which let them see thousands more colors than we can imagine. To understand this, Dr. Hanlon built a camera with sixteen color receptors, to be able to pick and choose receptors to imitate shark-vision or fish-vision. Dr. Hanlon was really kind and walked me through some of the hardware and software he’s been using to gather that data. It was so amazing to see!

Dr. Hanlon took me on a brief tour of the MBL labs, and I got to meet some of the cuttlefish, squid, and octopus that live there. They all had fun names, which I loved. One cuttlefish, Inigo Montoya, was very suspicious of the strange humans in his room, and changed his skin to have eyespots on the back of his mantle and a rippling white rectangle in the middle. Dr. Hanlon (the Cuttlefish Whisperer) has been studying cuttlefish for so long that he knows exactly what each display means, and was able to translate it for me!

I had a wonderful time talking with Dr. Hanlon. I was already interested in cephalopods, and in behavioral research, but talking with him made me really excited for my own journey as a diver and scientist. We talked about how we both prefer spending time in the ocean rather than in a lab, and he gave me some great pointers about using photography as a part of research. I’m heading to the Backscatter Digital Shootout as a part of my Internship, so I’ll be keeping his advice in mind as I get more familiar with underwater photography.

I will forever be grateful that Dr. Hanlon took the time to meet with me and show me his research, and for how interested in encouraging my own journey he was! It was a fascinating afternoon with a fascinating man.

My Internship has officially started! I spent the first several days in Cape Cod with Sea Rovers Vin and Kim Malkoski (the current BSR president!). Neither of them have seen me dive before, so we did several check-out dives to assess my buoyancy and to practice some skills. It’s been a while since I was in a drysuit, so it was really helpful to get that practice in too.

My first day was a big one: Vin and I went through all my gear, making sure I had everything I needed and that it was all set up correctly. We did our first check-out dive and since the weather was so lovely, and stopped for ice cream on the way home (Vin and I are both big on ice cream, I’ve learned).

That night, the Malkoski family and I drove up to Boston to see the first showing of Sea Rover Keith Ellenbogen’s short film Space to Sea: The Gulf of Maine’s Ocean Wilderness at the Museum of Science. We got to see the film on the huge IMAX screen of the Museum’s Mugar Omni Theater, and Keith spoke about the process and inspiration behind the film before showing it again. The images were all stunning, and did a great job showing the importance and beauty of New England’s ocean ecosystems. My favorite part of the film was a transition from a dark water column full of plankton fading to become stars in the night sky. It was a great night, and there were plenty of other Sea Rovers in attendance to support Keith!

In addition to my checkout dives with Vin, I also got to spend some time at Woods Hole Oceanographic Institute, where Kim is the Dive Safety Officer! We dove off the dock at WHOI, and I got to meet some of Kim’s colleagues and learn more about what she does in the Dive Office. 

I had the opportunity at the very end of the week to join the DAN Diving First Aid course that Kim was teaching – with so many researchers heading out soon, plenty of people needed to renew their First Aid and Rescue training. We learned how to properly give CPR, bandage wounds, recognize decompression sickness, administer emergency oxygen, and a whole lot more! I’m really grateful that Kim had me join the class, I feel much more prepared as a diver. It was also great to get a glimpse of some of the training that scientific divers like those at WHOI have to go through before they can join expeditions!
