Available in PDF, EPUB and Kindle. Book excerpt: free from any of the overtones that often constrain professional fisheries meetings. The present volume is the result. This volume aims to be useful as an appraisal of the state of the art by a mixed collection of insiders and outsiders. Most interestingly, I think, it aims (especially in the four group reports) to identify some of the major areas of unresolved controversy and some of the major questions yet unanswered. I see the book as essentially a tentative statement - often by several dissonant voices - about directions in which we may be heading; the book is emphatically not a canonical utterance on how to do things. It is intended to stimulate, not to codify. Following the usual Dahlem Workshop format, the discussions were organized under four themes. Although crisp demarcation is not possible, the first two themes broadly deal with biological aspects of the dynamics of single populations and the dynamics of systems with many species. The later two themes take up questions of management under uncertainty and multispecies management. In all this, the word "fish" is interpreted broadly to include such taxonomically varied beasts as whales, shrimp, crabs, shellfish, and squid, along with fish in a strictly zoological sense.

Download or read book On the Nature of Continental Shelves written by John J Walsh and published by Elsevier. This book was released on 2013-09-17 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the Nature of Continental Shelves discusses continental margins using techniques of systems analysis applied on minicomputers. The book describes insights and theories of mechanisms of enhanced primary production at the continental shelves, emphasizing these as the source energy, food, and recreation, and a possible means to detect global change while in its early phases. The text explains circulation, equations of motion, Ekman dynamics, and baroclinic effects of vertical changes in water density. Production in the seas involves the process of photosynthesis by organisms in which instruments on aircraft platforms can measure salinity and chlorophyll fluorescence. During photosynthesis, some of the light energy absorbed by phytoplankton pigments is emitted as fluorescence, at longer wavelengths, which can then detected. Adult fish and crustaceans are mobile and add a biological vector to the physical movement of organisms on the continental shelves. The book examines food limitation and the conditions of the Bering Sea, the Mid-Atlantic, and the Gulf of Mexico. The text also investigates sinking losses, present depocenters, atmospheric forcing, eutrophication, overfishing, and the effects of climate on primary production at the continental shelves. The book can be beneficial for students of meteorology, oceanography as well as to marine ecologists, biologists, and environmentalists.

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.
