Transport and fluxes across the bottom boundary layer


The major goal of this new subproject is to estimate transport and fluxes of solutes between the bottom boundary layer, the stratified interior ocean and the ocean mixed layer on the continental slope and shelf regions of the Peruvian and Mauritanian Oxygen Minimum Zones (OMZ). The objectives are achieved by estimating diapycnal and advective fluxes using two different methodological approaches: The first is based on the measurement of the radium isotope distribution in sediments and in the water column. The second approach uses a combination of oceanographic measuring systems for the determination of turbulences, currents and hydrography. Subproject A8 contributes to the understanding of the solute budget of the OMZ´s and establishes a link between the benthic and pelagic research foci within the SFB 754.
