Book excerpt: 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.
Download or read book Upwelling Ecosystems written by R. Boje and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Upwelling in the Ocean written by C. P. Summerhayes and published by . This book was released on 1995 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Physical Oceanography Processes at Eastern Boundary Upwelling Systems written by Francisco Machin and published by Frontiers Media SA. This book was released on 2023-12-29 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eastern boundary upwelling systems (EBUS) have historically received attention from the scientific community due to their impact on the economic development of these highly productive systems. Remote sensing, numerical modeling, and in situ observations have increased their spatial and temporal resolutions during the last 40 years in their strategy to provide reliable products about the actual state of the ocean. The assembly of several data sources currently constitutes an opportunity to increase our knowledge about the present and future state of the relatively narrow and highly variable EBUS. The primary forcing mechanism in the upwelling regions is the wind stress in areas close to the coast. Long-term trends in wind intensity in upwelling areas present considerable uncertainties as the different wind databases produce divergent results. On the other hand, although the effect of climate change in the interior ocean is increasing temperatures in upwelling areas, the long-term trends seem to be in the opposite direction. Hence, assessing the long-term impact of the environmental conditions on upwelling development represents a major challenge for the scientific community. This special issue aims to discuss the state-of-the-art understanding of dynamical processes governing the ocean at the eastern boundary upwelling systems in a changing ocean.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of a Symposium held at the University of Kiel, Germany, from 31 March to 6 April, 1971. The Symposium was organized by the Scientific Committee on Oceanic Research (SCOR) and the Marine Productivity section of the International Biological Programme (IBPIPM) with the assistance of the United Nations Educational, Scientific and Cultural Organization (UNESCO), the Food and Agriculture Organization (FAO), and the International Association of Biological Oceanography (IABO). The aim of the Symposium was to summarize present knowledge of the biology of the Indian Ocean. Twenty-two presentations by invited speakers reviewed the research work carried out during the International Indian Ocean Expedition (lIOE) 1959 -1965, the first cooperative project coordinated by the Intergovernmental Oceanographic Commission (IOC). In addition, reports were presented of postexpedition examination of material and of more recent investigations relevant to the aims of the lIOE. In keeping with the aims of "Ecological Studies", the present volume contains much new information and some synthesis, all directed towards obtaining an understanding of the functioning and organization of the ecosystem of the Indian Ocean. The plan of the Symposium was to present the relevant meteorological, physical, chemical and geological background and to follow this with the various aspects of biological oceanography. Because of the uneven stage of development of the different disciplines, the papers included in this volume vary in their analytical level.

Book excerpt: Return to the River will describe a new ecosystem-based approach to the restoration of salmon and steelhead populations in the Columbia River, once one of the most productive river basins for anadromous salmonids on the west coast of North America. The approach of this work has broad applicability to all recovery efforts throughout the northern hemisphere and general applicability to fisheries and aquatic restoration efforts throughout the world. The Pacific Northwest is now embroiled in a major public policy debate over the management and restoration of Pacific salmon. The outcome of the debate has the potential to affect major segments of the region's economy - river transportation, hydroelectric production, irrigated agriculture, urban growth, commercial and sport fisheries, etc. This debate, centered as it is on the salmon in all the rivers, has created a huge demand for information. The book will be a powerful addition to that debate. - A 15 year collaboration by a diverse group of scientists working on the management and recovery of salmon, steelhead trout, and wildlife populations in the Pacific Northwest - Includes over 200 figures, with four-color throughout the book - Discusses complex issues such as habitat degradation, juvenile survival through the hydrosystem, the role of artificial production, and harvest reform
