In particular he has described the movements, horizontal and vertical, of the water between the Antarctic Continent and the northern limits of the Southern Ocean, defining Antarctic and Sub-Antarctic areas which are proving significant in the study of the distribution of plankton and of free-swimming and bottom-living animals. He has shown that practically all the bottom water of the Antarctic origin in all the oceans is formed in the Weddell Sea."
This individual has detailed the movements of water, both horizontally and vertically, between Antarctica and the Southern Ocean's northern boundary, defining areas of significance for studying plankton distribution and the movement of free-swimming and bottom-dwelling animals. He has demonstrated that all bottom water originating from Antarctica in every ocean is formed within the Weddell Sea.
