Biological tests carried out on the natural populations of the Basin show that P is the first biomass-limiting element and that N is the second. The simultaneous input of P and N, however, is not sufficient to induce growth; this suggests that Mn has an essential role in the phytoplanktonic growth in this ultra-oligotrophic water. Discussion deals with the significance of the deep chlorophyll a maximum and with the physiological processes allowing it to last. PY 1984 PD NOV CT Actes de colloques. Ifremer. Brest [ACTES COLLOQ.
