Interactive comment on “Biological productivity in the Mauritanian upwelling estimated with a triple gas approach” by T. Steinhoff et al

General Comments The authors present a novel approach for calculating net community production (NCP) in eastern boundary upwelling systems using data from the Mauritanian Upwelling as a case study. Their calculations rely on a triple gas approach (N2O; CO2 and O2), though O2 is primarily used to validate the results derived for CO2. Briefly, N2O is used as a quasi-inert tracer of recently upwel...

Comparative study of potential transfer of natural and anthropogenic cadmium to plankton communities in the North-West African upwelling.

A Lagrangian approach based on a physical-biogeochemical modeling was used to compare the potential transfer of cadmium (Cd) from natural and anthropogenic sources to plankton communities (Cd-uptake) in the North-West African upwelling. In this region, coastal upwelling was estimated to be the main natural source of Cd while the most significant anthropogenic source for marine ecosystem is prov...
