We are a @NSF Science and Technology Center that explores how metabolite exchange through microbial networks impacts carbon cycling in the surface ocean
Woods Hole MA
Joined January 2020
Henry's PhD research investigated how marine phytoplankton adapt their lipid membranes to a range of environmental conditions. Now he studies how phytoplankton may cycle carbon differently in future oceans that are hotter & more acidic using culturing and 'omics methods.

📣#MTTM Dr. Henry Holm is a postdoc researcher working with C-CoMP and the Dyhrman and Hurley lab groups @Columbia @lamontdoherty. He is a chemical 🧪oceanographer by training and thinks a lot about how phytoplankton move carbon through the ocean 🌊.

🌊🦠#FieldworkFriday! C-CoMP focuses on microbes & chemicals, so it is easy for us to forget how vast our ocean is. Being at sea 🚢 is the loveliest reminder - there’s nothing as wondrous or humbling as floating in endless cerulean blue while receiving rare visits from animals🐦!

The conditions that lead to successful infection of phytoplankton in the wild are poorly understood. Annika seeks to unravel the role of nutrient stress in determining susceptibility to viral infection and apply this knowledge to isolate novel phytoplankton-virus pairs.

Had a fabulous time meeting with C-CoMP members last week at our Annual Meeting in Woods Hole. Thanks for all the great discussions 🧪🌊🦠💻🚢🌎! We are looking forward to an exciting year of investigating bioreactive molecules within the marine chemical-microbial network!

🌊🦠#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!

@rogier_braakman @MIT Mariana is motivated to explore questions at the intersection of physics, biogeochemistry, and biology, to understand how these processes interact + what role they play in the global state of the ocean. They are excited to apply to doctoral programs in oceanography this fall!

@rogier_braakman @MIT Alongside this work, they collaborate with their C-CoMP B2P cohort to study how ocean extremes (#marineheatwaves 🌡️), impact phytoplankton ecosystem dynamics through satellite observations 🦠🛰️.

🌊🦠#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 @BgcAuv, eddy sampling, & 9 exp types across 3 locations - to characterize marine chemical currencies & microbes!

@jillianpaquette @DyhrmanLab @LamontEarth @Columbia Jill is interested in marine biology & oceanography 🌊. Her interest in expanding her knowledge of ocean systems and biogeochem before applying to graduate PhD programs led her to join C-CoMP. Jill is excited for her second year in the program and to apply to graduate programs!

🌊🦠#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!

🌊🦠#FieldworkFriday! During the C-CoMP March Cruise, Clio, the biogeochemistry AUV (@BgcAuv), 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:

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 & @DyhrmanLab @LamontEarth for creating this activity!

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