Abstract

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).
