Many evaluations of the resources of polymetallic nodules have been published in the past, but few were established from the data acquired recently by the mining companies. As it was emphasized recently by the SIO group that devotes a lot of research effort in compiling the available data on manganese nodule: "The lack of abundance measurements, particularly in those areas where we have a good idea of nodule grade portends a doubtful future for meaningful resources projections" (Frazer, 1979). In this paper we want to discuss the data, already published and newly released, and to analyse their significance in matter of nodules resources and reserves. © 1981.
