Dissolved organic carbon (DOC) production by microbial populations was measured at 19 stations in the Atlantic Ocean to quantify fraction of photoassimilated that flows through dissolved pool basin scale and assess relationship between percentage DOC production, phytoplankton size structure, rates net community production. Experiments were conducted during four cruises carried out May 1998 October 1999, covering three upwelling regions: Benguela (SW Africa), Mauritania (NW Africa) NW Spain,...

Abstract Despite its importance to ocean–climate interactions, the metabolic state of oligotrophic ocean has remained controversial for >15 years. Positions in debate are that it is either hetero- or autotrophic, which suggests substantial unaccounted organic matter inputs, all available photosynthesis (P) estimations (including 14 C) biased. Here we show existence systematic differences North (heterotrophic) and South (autotrophic) Atlantic gyres, resulting from both P respiration (R)....
A comprehensive in situ dataset of chlorophyll a (Chl a; N = 18,001), net primary production (NPP; 165) and community (NCP; 95), were used to evaluate the performance Moderate Resolution Imaging Spectroradiometer on Aqua (MODIS-A) algorithms for these parameters, South Atlantic Ocean, facilitate accurate generation satellite NCP time series. For Chl a, five tested using MODIS-A data, OC3-CI performed best, which was subsequently compute NPP. Of three NPP tested, Wavelength Resolved Model...

The Mauritanian upwelling system is one of the most biologically productive regions world's oceans. Coastal transfers nutrients to sun‐lit surface ocean, thereby stimulating phytoplankton growth. Upwelling deep waters also supplies dissolved inorganic carbon (DIC), high levels which lead low calcium carbonate saturation states in waters, with potentially adverse effects on marine calcifiers. In this study an upwelled filament off coast northwest Africa was followed using drifting buoys and...
