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...
