Meyer-Kaiser lab

The ROV we used to record video today I was on a Zoom call about my offshore wind project  when one of the consultants brought up a familiar name: Marine Imaging Technologies. The small Massachusetts-based company had been sub-contracted to collect video data using a remotely operated vehicle. As the benthic ecology expert on the project, I was responsible for ensuring the video recordings were high quality and clearly showed the seafloor community. I needed to join Marine Imaging staff for a day at sea.  I gave a wide smile. I was about to get paid to spend a day on a boat with my friends. Marine Imaging Technologies owner, Evan, and his deputy, David, were key players in our 2019-2020 Stellwagen Telepresence Project , and we collaborated on a project in the Gulf of Mexico in 2022, too. When I stepped onto R/V  Catapult  at 6:30 am, both Evan and David greeted me with warm hugs. The last time I saw them was in April in Portland, Maine, for a public event celebrating the Portland

It has been a big week for the Meyer-Kaiser lab. My anemone experiment is going swimmingly (pun intended!); Kharis recovered CATAIN successfully in the Arctic; and Johanna has made incredible progress on DeepZoo .  Johanna sent me this photo to celebrate that DeepZoo's housing passed its pressure test! Most of the DeepZoo work happens at WHOI's AVAST engineering hub, so I'm not there in person to see every step. I learn of Johanna's victories through her joyful texts and videos she sends at key moments. This week, she had two to share. First, the titanium housing that holds DeepZoo's electronics passed its pressure test! This is actually a pretty big deal, because the housing has to withstand 1100 atmospheres of pressure. DeepZoo was designed to work at all ocean depths - right down to the deepest point, the Challenger Deep. The custom full-ocean-depth housing was machined out of titanium. It's incredibly precise work, not to mention that the housing has three

Our Oktoberfest outfits! A little over a year ago, my husband, Carl, and I visited Colorado. Carl spent some of his childhood in Colorado; he studied at Colorado State University, and his first job was in Colorado Springs. His parents live outside of Denver, and many of his college and grad school-era friends are still in Fort Collins. We had a busy visiting schedule that trip, but one moment in particular stood out to me. Carl's best friend from college threw a barbecue in Carl's honor, and about 20 people showed up. It was magnificent. Most of the friends Carl left behind when he moved Massachusetts are still in contact with one another, and in fact, the circle has grown over time. They brought their kids. They hugged us, but they were also happy to see each other. That night in Fort Collins was a beautiful expression of community.  We came back home after that trip with a question: "How can we create a stronger sense of community on Cape Cod?" I spent a lot of time

"Be the kind of woman who, when your feet hit the floor each morning, the devil says 'Oh no! She's up!'" - Joanne Clancy My alarm went off at 7, like usual. As I picked up my phone to silence it, I noticed a text message from Kharis, my PhD student: "She's up!" I sank back into the pillows and let out a deep breath. Wonderful. She's up. Thank goodness.  "She" in this context is CATAIN , the camera system that my lab invented a few years ago. CATAIN is specifically designed to capture settlement - the process of a larva metamorphosing and attaching to its new juvenile habitat on the seafloor. A lot of animals die right after they settle, so it's really difficult to study settlement itself. Most of the time, researchers leave out fouling panels and then collect them with all the attached animals a few months later. The problem with that strategy, though, is you only see the sum total of everything that settled and everything that die

Settled larvae in my culture dishes I sat down at the microscope with a dish of anemone larvae in one hand and a glass pipet in the other. Time for a water change. For about a week and a half, I had been tracking everything I could about my Metridium senile larvae - size, shape, buoyancy, swimming speed, survival. All those parameters would inform a high-resolution model of their dispersal, so I needed to record everything.  Peering into one of my dishes, I noticed something I hadn't seen before: small blobs attached to the glass. They were about the size and shape of a larva, actually. Same color, too. I sucked up a little water with my pipet and blew it on one of the blobs. The blob did not move. It was firmly attached to the dish.  Zooming in, I noticed that the blobs had a bit of internal structure. A central point, some pale lines radiating out from it. A mouth and septa. Just like a juvenile anemone.  Ladies and gentlemen, we have settlement! Those blobs can only be one thin

Two project team members bringing the grab  on board Tioga , hopefully with a good sample! As a benthic ecologist, I've taken plenty of grab samples in my day. It's pretty much a staple of the field. You lower a grab over the side of a boat, scoop up some sediment, sieve it, and preserve the animals. Every benthic ecologist knows how to collect a good grab sample. I can't even tell you how time I've spent sieving sediment samples in the field. The whole process is second nature by now.  As you might guess, grab sampling is not second nature for everyone. Recently, I had the opportunity to bring others up to speed when a local consulting company asked me to partner with them. I joined the team on WHOI's boat, R/V Tioga , as the resident expert on benthic ecology.  It was a fun trip. Two of the consultants deployed and recovered the grab - they didn't need me for that part. But once the sampler was on deck, I had to check it. Ideally, you want a grab that fills t

A Metridium senile larva I pulled into the parking lot at work. It was 6:30 am. Every morning, I stopped by the lab before my safety training class to take care of my larvae. Every afternoon, I went straight back to the lab as soon as my training was finished. Sure, I was burning the candle at both ends, but I was getting amazing data.  I have wanted to study the larvae of Metridium senile for several years now. I actually had a lightbulb moment in 2017, when my husband dragged me to a dive show north of Boston. We had just started dating, and he wanted to get me interested in SCUBA diving (the plan may have worked a   little too well ). There was an exhibit at the dive show about the shipwreck Andria Doria , which rests just south of Nantucket. As we walked through the exhibit, I stopped short. Every photo of the shipwreck on display that day had the same species in it: Metridium senile . I new Metridium well - it was the dominant species on a shipwreck I studied in grad school.
