-Recent studies undertaken by the Centre National pour l'Exploitation des Oceans have focused some attention on th(; environment of nickel- and copper-bearing iron-manganese nodules in the Tuamotu Archipelago region of the South Pacific. The results indicate that the distribution of the nodules is closely linked to that of deep currents in the area. We attempt to show that these currents are associated mainly with the Antarctic Bottom Water and we attribute the episodical character of nodule formation in this region to major pulsations of the Antarctic Bottom Water. A synthesis of what are considered to be primary factors in the nodules formation are incorporated into a tentative rnodel which is presented as a guide for future exploration for polymetallic nodules.-
