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!
Woo, riding around the edge of an eddy and sampling for omics and sensors- new use case. I was recovered at the blue dot - started at a red dot to the right, drifter track in the center. Eddies can bring nutrients towards the surface and stimulate productivity. Also useful for robot joyrides.
