SWOTALIS: scientific campaigns to better understand the dynamics of the ocean around the seamounts south of New Caledonia

During SWOTALIS, three lines of instrumented moorings recording every 20 minutes variations in currents and density over the entire water column will be deployed for 8 months. Water will be sampled every three hours to understand how these waves impact the presence of nutrients in the surface layer of the ocean, and plankton.

Finally, innovative instruments will be deployed: the RapidCast/ecoCTD, which produces continuous density profiles of the ocean while the ship is traveling at low speed, associated with a GPS sheet which, dragged behind theAntheawill simultaneously measure sea level with high accuracy.
