Upwelling systems are special places in the oceans where nutrient-enriched water is brought into the euphotic zone to fuel phytoplankton blooms that, via marine food-web interactions, create the world’s richest fish resources. This book introduces the reader to the interdisciplinary science of upwelling and provides a comprehensive overview of the world’s most productive marine ecosystems in the context of climate variability, climate change and human exploitation. This material presented is suitable for undergraduate and postgraduate study or just for anyone interested to learn about the creation of life in the oceans and how this is compromised by human activities.

Upwelling is one of the major physical processes driving the biogeochemistry of the ocean system. It dominates primary productivity in the world?s oceans, accounting for 80?90% of new production. However, because of the physical conditions that have to be met to generate upwelling, this production is concentrated in just a few places, e.g., in the coastal waters of major eastern boundary currents off California, Peru, Mauritania, and Namibia, where productivity leads to major fishing grounds. These areas account for about 50% of the world?s fish catch, underlining the importance of upwelling to humankind. Source rocks for oil formed in ancient coastal upwelling environments, making their study useful for improving oil exploration models. Upwelling also occurs in the open ocean, especially along the equator and beneath the westerly winds in the subarctic Pacific and the Southern Ocean, where the ocean?s silica budget is transformed by the deposition of the remains of siliceous phytoplankton. Because phytoplankton, the grass of the sea, can extract CO2 from the atmosphere, changes in the intensity of upwelling and associated biological productivity through time may have influenced climate. This volume uses an interdisciplinary approach to establish how upwelling systems work, how they vary through time, and whether or not they have a significant influence on the global carbon cycle. An understanding of how these largely wind-driven biogeochemical systems work today, and how they responded to past fluctuations in climate, is essential in predicting how they and their associated living resources may change in the future. One conclusion is that these systems exert a major influence on the global cycle of nutrients, a factor that contributes to making the coastal regions major sinks for organic carbon. This book recommends new strategies for observation, sampling, monitoring, experimentation, and modeling as the basis for improving forecasts of the behavior of upwelling systems. It will be of interest to physical oceanographers, marine biologists, fisheries scientists, marine organic and inorganic chemists, marine geologists, petroleum explorers, paleoceanographers, and paleoclimatologists.

Upwelling areas are among the most fertile regions of the ocean. In principle, upwelling is caused by the divergence of the flow in the surface layer of the ocean which arises as a consequence of a particular wind field, the presence of a coastline, or other special conditions. Since deeper oceanic layers are usually enriched wi th nutrients, it is the permanent supply of nutrients which forms the basis for the high producti vi ty of upwelling reg ions. The study of upwelling and its consequences were, for a long time, the task of individual scientists from all disciplines of marine science. Today, it is perhaps the branch of oceanography where interdisciplinary coopera tion has developed best. Becoming aware of the large potential yield of upwelling regions, governments in creased the funds for upwelling research. With research activities developed on a larger scale, interdisciplin ary cooperation became a necessity. On the international level, several symposia documented the rapid development. Three volumes reflect the results of these scientific meetings (Rapp. Proc.-Verb. 159, 1970; Inv. Pesq. 35, 1, 1971; Tethys §.' 1-2, 1974). The present book contains selected papers from the Third Symposium on Upwelling Ecosystems, which was held in Kiel in September 1975. Although the third of a series of meetings, it was the first where the word "ecosystem" stood in the title for a scientific program.

An upwelling is a rise of deep sea waters to the surface. A minimum of four types of upwelling have been identified: coastal upwelling; large-scale wind-induced upwelling in the open ocean; upwelling related to tropical cyclones; and upwelling related to topography. In this book, the authors present current research in the study of the mechanisms, ecological effects and threats to biodiversity due to upwelling. Topics discussed in this compilation include the ecological effects of coastal upwelling in Cabo Frio, Rio de Janeiro, Brazil; Namibian upwelling and its effects on macrozoobenthic diversity; mechanisms of impact on chlorophyll and upwelling in the Northern Black Sea; distribution, mechanisms, and biologic and climatic significance in upwelling and downwelling.

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.
