Once again I am back with more Oceanly, and Inkfish, related adventures. In Turks and Caicos this time. The Oceanly team is looking for internal waves here too, and I am here to provide a biological look into it, along side a researcher from the Auckland Museum. I am using a newly acquired PlanktoScope v2.6, and they are doing fancy eDNA sampling.

BPQ

As customary, the 5 days quarantine to make sure we don’t bring any diseases on the boat. It gave me time to get to talk with great marine geologists from Kelpie Geoscience in the UK. Fabulous people, very (very) rock oriented. And I met one of the mappers from RV-Hydra, just as fabulous.

eDNA

The cool thing with eDNA is that it can tell you what was around in the last 24 to 48 hours. That is really awesome, and pairs really well with the instantaneous detection from the PlanktoScope.

Hydra

Hydra’s crew was amazing, as always. And we got 9 new niskin bottles of 12L, which meant more water sample!! That was really nice considering there was two of us needing them. We were also able to use a multispectral drone to see specific wavelength and try targeting internal waves from above! That really made me want to get a drone pilot licence. I’ll add that to my 2026 to-do list.
