Four CARIOCA Lagrangian buoys
drifted in the North-East Atlantic Ocean
between 38° and 45°N between February and August 2001. Daily cycles of pCO2, SST and DIC are
observed even in winter. Biological rates of carbon consumption, gross and net
primary production,are determined in situ from the amplitude of the diel cycles
and the time evolution of surface dissolved inorganic carbon. Over the 6 months
period, February-August, the ocean in the studied area is a sink for atmospheric
CO2.The mean absorbed flux is equal to 3.8 mmoles/ m2/ day.
