Esporles, July 19, 2017. Today has started the IRENE-CALYPSO campaign for the investigation of vertical exchanges in the surface layers of the ocean in the Western Mediterranean, funded bky the US Office for Naval Research (ONR).


IRENE is a collaboration between IMEDEA (UIB-CSIC) and SOCIB in Mallorca, Spain and the Woods Hole Oceanographic Institution, Massachusetts, USA.



Today, July 19, the SOCIB Research Catamaran has left Mallorca for the Alboran Sea, with eight scientists and eight crew members on board to sample the Almería-Oran front for a week. The goal is investigate vertical transport and exchange of water at the front.

 

The SOCIB Research Catamaran is outfitted with instrumentation and gliders (or autonomous underwater robots) to traverse a region of strong density contrast between the salty Mediterranean water to north and fresher Atlantic water to the south. This is also a region of strong currents, and drifting instruments that relay their position via satellite in real time, will reveal the pathway of water in this region.

 

 

While underway, the ship will deploy and recover instruments (CTD, underwayCTD and gliders or autonomous underwater robots) to measure salinity and temperature over the upper 300 meters at frequent intervals. A buoy with subsurface instrumentation will record velocities at the front.

 

 

The different phytoplankton communities at the front arising from the physical conditions will be discerned through sequencing and cytometry. .
