Overnight work!

A lot of work was carried out last night. The samples and biological specimens brought back on board the ship by the ROV had to be identified, measured, labeled, recorded and put in formalin or ethanol to be preserved. Pictures of each of them were taken. Some samples were saved for DNA analysis. It’s a huge amount of work!

In the meantime, Jane put an instrument in the water that measures turbulence, temperature, salinity and pressure (depth). It started at 10:30 pm and went on until midday today measuring these parameters between the surface and 250m in repeated vertical profiles. We can learn a lot about mixing and physical processes in the water column above the seamount this way.
