SUBPROJECT - B9
Near-coastal supply of oxygen and dissolved organic matter to the oxygen minimum zone
B9 tests the hypothesis that meso- and submesoscale physical processes related to upwelling regimes are responsible for the episodic advection of oxygen and of dissolved organic matter (DOM) from the surface to the OMZ. In-situ high-spatial-resolution glider-based measurements are combined with CTD sampling to determine the meso- and submesoscale hydrography and circulation, and the distribution and composition of DOM in upwelling zones off Peru and Mauretania. A better understanding of the physical-biogeochemical coupling relevant to OMZs in the ocean shall thus be achieved.
