Produktbeschreibung

NATO Advanced Research Institutes are designed to explore unre solved problems. By focusing complementary expertise from various disciplines onto one unifying theme, they approach old problems in new ways. In line with this goal of the NATO Science Committee, and with substantial support from the u.s. Office of Naval Research and the Seabed Assessment Program of the U. S. National Science Founda tion, such a Research Institute on the theme of Coastal Upwelling and Its Sediment Record was held september 1-4, 1981, in Vilamoura, Portugal. The theme implies a modification of uniformitarian thinking in earth science. Expectations were directed not so much towards find ing the key to the past as towards exploring the limits of interpret ing the past based on present upwelling oceanography. Coastal up welling and its imprint on sediments are particularly well-suited for such a scientific inquiry. The oceanic processes and conditions characteristic of upwelling are well understood and are a well packaged representation of ocean science that are familiar to geolo gists, just as the magnitude of bioproduction and sedimentation in upwelling regimes --among other biological and geological processes- have made oceanographers realize that the bottom has a feedback role for their models.
