N 2 fixation rates were measured during the KEOPS2 cruise in the HNLC area of Southern Ocean and in naturally iron-fertilized waters (Kerguelen Island 49.25° S, 69.58° E) using the 15 N isotopic technique. We detected N 2 fixation within the mixed layer at all stations, from the surface to 140 m dep...
