Microstructure profiles
Microstructure profiles from the N/O Pourquoi Pas? are done! This instrument, operated by Francesco Falcieri coming from an Italian Institute based in Venice (CNR-ISMAR), will be moved onto the RV SOCIB during our port call in Almeria on April 3rd.
The profiler free-falls vertically through the water column to measure very small vibrations at scales of centimetres. Scientists used those measurements to infer turbulence activity in the ocean that mixes water irreversibly. But the profiler also measures other variables, such as temperature, conductivity, turbidity and fluorescence. We collected 43 profiles over this first week – with more to come from the RV SOCIB!

Science meetings
We meet for a science meeting at 6:15 every day.

Water sampling
The water sampling lab was busy processing the sea water samples for phytoplankton, nutrients and oxygen.

-
- As Margaret filters seawater to determine the phytoplankton community structure, we find a phytoplankton predator, a salp!!
-
- A group of salps were found on the CTD. Eva carefully returned them to sea.
Samples are underway!
