Project DIAPICNA -DIAzotrophic PIco-Cyanobacteria in the North Atlantic open ocean: their abundance and importance as a source of new nitrogen at the Azores Front/Current

International audience Nutrient concentrations indicate an oligotrophic area with nutrient bottom regeneration at the North of the Azores Current Front (Station 4, 35°N, Graph 2, Left). Nitrate isotopes indicate nitrate assimilation at Station 4, while depleted signatures South of the Front might re...

Description
Summary:International audience Nutrient concentrations indicate an oligotrophic area with nutrient bottom regeneration at the North of the Azores Current Front (Station 4, 35°N, Graph 2, Left). Nitrate isotopes indicate nitrate assimilation at Station 4, while depleted signatures South of the Front might result from N 2 fixation (Graph 2, Right).
