Available in PDF, EPUB and Kindle. Book excerpt: One of the major environmental consequences of Ocean Thermal Energy Conversion (OTEC) plans may be the artificial upwelling of nutrients to the surface waters of oligotrophic ecosystems. Within a 10 km2 area, OTEC plants of 1000 MWe total capacity could upwell the same amount of nutrients as occurs naturally off Peru each day. The biological response to possible eutrophication by OTEC plants may not be similar to that within coastal upwelling ecosystems, however. Upwelling in offshore oceanic systems does not lead to increased primary production despite high nutrient content of the euphotic zone. Continuous grazing may not allow phytoplankton blooms to develop in oceanic upwelling systems to the proposed OTEC sites. At present this is a hypothesis to be tested before full evaluation of OTEC induced upwelling can be made.

Book Synopsis Clean Coastal Waters by : National Research Council
Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.
Book Synopsis Ocean Artificial Upwelling – Ecological Responses and Biogeochemical Impacts by : Ulf Riebesell
Download or read book Ocean Artificial Upwelling – Ecological Responses and Biogeochemical Impacts written by Ulf Riebesell and published by Frontiers Media SA. This book was released on 2024-09-20 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feeding a growing human population and achieving net-zero CO2 emissions by 2050 are the great challenges of the 21st century. Whilst terrestrial resources are already utilized intensively by competing societal sectors, the vast ocean ecosystems still hold untapped potential. The productivity of the ocean is, however, limited by the transport of nutrient-rich deep waters to the sun-lit surface layer. In large parts of the global ocean, this transport is blocked by a temperature-induced density gradient, with warm light waters residing on top of heavier cold waters. The upward transport of nutrient-rich deep waters through artificial upwelling can break this blockade and enhance primary production. However, little is presently known about the ecological responses to forced upwelling in oligotrophic waters, their impacts on biogeochemical cycling and possible feedbacks to the climate system. In view of its potential contribution to securing marine food production and mitigating climate change, a comprehensive assessment of the feasibility, effectiveness, and associated risks of artificial upwelling is of particular scientific and societal interest.

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 Fate and Effects of Oil in Marine Ecosystems written by J. Kuiper and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: A. Rorsch Member of the TNO Board of Management Like all living creatures man has from the very outset influenced the environment. Initially, the traces of human activity were hardly noticeable and so were their effects on the equilibrium of the ecosystem as such. However, as soon as man learned how to use tools, he was able to influence his surroundings more drastically, and to proliferate more rapidly. As a matter of fact that is the time when things went wrong, because a process was started off which was to continue with ever-increasing speed and on an ever increasing scale. The present condition of nature as a result of the activities of mankind is generally known. Whether it is an accident with a nuclear plant or the vanishing of tropical rain forests, acid deposition or the pollution of soil, water and air, environmental disasters almost seem to be the order of the day. It is striking that with all these - more or less arbitrary - examples the provision of energy plays a role. In this respect one can add an even more important energy carrier to the list, namely: crude oil.
