Once the CTD landed 🛬 on deck, the research team would quickly gather around it to collect seawater into vials and carboys for various forms of downstream processing, including lots of filtering, to capture and separate microbes 🦠 and particles from the seawater 🌊!

🌊🦠#FieldworkFriday! During the March 2025 cruise, C-CoMP deployed 68 CTD casts in 12 days. A few casts profiled chemical/biological properties of the water column 🌊 down to a few hundred meters, but 64 casts were used to investigate diel microbial dynamics at 15 meters 🦠☀️🌛!

Researchers and crew braved three storms, with 30-40 kt winds and 10-20 ft seas. Despite weather delays and interruptions, the team successfully and safely completed the core mission of the cruise and collected hundreds of samples! Video by Daniella Asturias.

🌊🦠#FieldworkFriday! Last March, C-CoMP set out on the RV Atlantic Explorer to compare diel surface ocean microbial dynamics between oligotrophic and productive regions. Time to batten down the hatches! Photo by McKenzie Powers.
