🌊🦠#FieldworkFriday! Once seawater lands on deck, it’s go time 🏁! Researchers frequently spend hours in the lab each day and night (!) filtering and processing samples and running incubations. Here are a few snapshots from lab work during the C-CoMP 2025 March Cruise, AE2504!

📣#MTTM Mariana Torres (martorres.bsky.social) is a C-CoMP B2P Fellow working with @rogierbraakman.bsky.social @mit.edu. Using computational methods, they are investigating environmental drivers of carbon cycle metabolism dynamics in the North Atlantic Ocean 🌊.

🌊🦠#FieldworkFriday! And that’s a wrap 🎬on C-CoMP Cruise 2 🚢! We (C-CoMP + AE) accomplished an impressive feat - 95 CTD casts, 110,778 L of sw filtered with @clio-thebgcauv.bsky.social, eddy sampling, & 9 exp types across 3 locations - to characterize marine chemical currencies & microbes!

📣#MTTM Jill Paquette is a C-CoMP B2P fellow working in the Dyhrman Lab @lamont.columbia.edu @columbiauniversity.bsky.social. She uses computational approaches and lab culturing methods to investigate how nutrient stress affects the gene expression of eukaryotic phytoplankton 🌊🦠.

🌊🦠#FieldworkFriday! During our March cruise, C-CoMP researchers deployed SVP drifters during diel sampling. The drifters enabled tracking/sampling the same parcel of water in a Lagrangian approach, aiding efforts to capture diel microbial signals from the same water over time!

Successful dive and recovery to the eddy center, 18 sample depths down to 800 meters deep and engineering tests completed too.

Hey - check it out! @clio-thebgcauv.bsky.social is exploring an eddy during the second C-CoMP cruise! We are excited to see how the eddy impacts microbial and metabolite dynamics. Stay tuned!

We're out at sea with C-COMP @microbialplanet.bsky.social and the AUV Clio. Clio's social media account has migrated from the other place to the blue place @clio-thebgcauv.bsky.social , follow for mild sarcastic pseudo-first robot humor updates...

Currently I'm at sea supporting C-COMP's chemical currencies research in the North Atlantic Ocean. (@microbialplanet.bsky.social).

🌊🦠#FieldworkFriday! During the C-CoMP March Cruise, Clio, the biogeochemistry AUV, was used to collect particle samples for proteomics and metagenomics from various depths within the water column. Check out some of these photos of Clio in action:

Check-out this new paper on vitamin auxotrophies by @rachelgregor.bsky.social, a former C-CoMP Postdoc, and colleagues. Great job team! 🧪

C-CoMP participated in the 2025 Woods Hole Science Stroll! Our booth, called the “Artistic Oceanographer”, invited visitors to explore & imagine incredible adaptations of marine phytoplankton. Thanks to our volunteers & the Dyhrman Lab @lamont.columbia.edu for creating this activity!

🌊🦠#FieldworkFriday Our fieldwork doesn't only happen at sea! C-CoMP researchers working with @maratimes.bsky.social collected Providence River water to test extraction methods for samples collected on C-CoMP cruises. In terms of filtering speed, 5 L of Sargasso sw = 50 mL of Providence River water!
