Description:
A synthesis is given of the present knowledge of the topographic and sediment characters of the sea floor of the Argentine Sea. After considering some general characters of passive continental margins the Argentine characteristics are described. Various 'physiographic provinces' are differentiated. The corresponding to the continental shelf is the most extensive on its several 'terraces' associated with Plio-Pleistocene sea level changes. Soft sediments are dominant,mainly being composed of sand with minor but varied quantities of shells and mud. Harder bottoms, composed of loose gravel and rocky outcrops are also present. The information presented here is not sufficient for evaluating the natural resources of the Argentine Sea or for solving sovereignty claims. It is evident that more complete studies must be done in order to get a full panorama of the physical characters of the Argentine continental shelf.
