Its objective is to determine the organic carbon balance of the planktonic community of the Canary Region, and the causes of its variation between the coastal zone of North-West Africa, highly productive, and the zone of low biological production of the Subtropical Gyre, as well as the exchanges of organic carbon between these two systems.Four experiments were conducted along a range from highly oligotrophic to productive environment
