Amazon iNfluence on the Atlantic: CarbOn export from Nitrogen fixation by DiAtom Symbioses (ANACONDAS)

This research project sutided the effects of the Amazon River plume on the carbon and nitrogen cycling of the western tropical North Atlantic Ocean. Phytoplankton blooms triggered by the river plume are thought to be responsible for significant cabon dioxide drawdown from the atmosphere. Our team came together to try to understand the factors affecting the phytoplankton bloom and also the fate of its production, including the amount of carbon dioxide taken up by the plume. Fieldwork in the western tropical North Atlantic onboard the RV Knorr took place along the salinity gradient of the river plume (16 ppt to 36 ppt) at a series of stations within and adjacent to the pluem.
