STATION AUTONOME D'OBSERVATION DES COMPOSANTES BAROTROPE ET BAROCLINE DE LA CIRCULATION OCEANIQUE

Objective

The BABAS project consists of the realisation of two new complementary oceanographic instruments.

One of the instruments, a seafloor electrometer, will monitor the barotropic component of the oceanic circulation. It measures the natural electric field on the sea bottom that is directly related to the integrated velocity of the water column at frequencies less than 1 cycle per day.
The other one is a VCTD-yoyo. Classical parameters (velocity, temperature, conductivity, pressure) will be recorded with this vertical profiler along a tight cable in order to detail the structure of the water column. The VCTD-yoyo will monitor the baroclinic component of the oceanic circulation.
Several instruments will be built to monitor the total mass and heat transports and their vertical structure, and to determine the spatial structure of the oceanic circulation in addition to its temporal variations. Furthermore, the integrated velocity will provide the necessary absolute reference to analyse the CTD profiles.
