Description
Summary:The marine biological pump, consisting of organic carbon production, export and remineralization, is an essential component of the global carbon cycle and exerts an important control on atmospheric carbon concentrations. Lateral fluxes of organic carbon out of their region of production, especially from coastal regions, may explain the large rates of remineralization in regions of low productivity, but they are currently unaccounted by export and budget estimates. Here I quantify and characterize this lateral offshore transport of organic carbon from the north-western African coast of the Canary Upwelling System (CanUS) up to the middle of the oligotrophic North Atlantic Gyre. To this aim, I run the physical Regional Oceanic Modeling System (ROMS) coupled with the biogeochemical-ecosystem Nutrient Phytoplankton Zooplankton Detritus (NPZD) model on an Atlantic telescopic grid. This newly developed grid covers the entire Atlantic basin, allowing to study the lateral transport on very large spatial scales, and ...
