Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - From a general point of view the importance of striving to minimize envir- mental disturbances on the continental shelf cannot be overemphasized. Coastal areas are sites of population centers, navigation and recreation activities, and - source development, all of which contribute to environmental stress on the shelf. Proper management of the shelf for optimum use requires a thorough understanding of shelf processes. Complex problems, such as the influence of hydrodynamics on sediment dispersal, element differentiation and migration, physiochemical changes at the sediment water interface, the relationship - tween the pollutants and sediments, and the type of substrate with regard to benthic community and/or man-made structures require a multidisciplinary approach to their solution. The present study interrelates meteorologic, hyd- graphic, sedimentologic, and geochemical parameters to derme specific envir- ments on the Alaskan Shelf. These observations are then related to geologic principles in an effort to elucidate the sedimentary processes and elemental migration on the shelf. Attempts have also been made to relate the sediment texture to the geochem- try of the sediments. Obviously the chemistry is complicated as a result of b- genic contributions and variable provenance; however, to some extent elemental differentiation accompanies textural differentiation in sediments. The distribution of elements in various phases of crustal (source) rocks is gen- ally interpreted on the basis of crystallographic concepts, especially the concept of isomorphism.

The initial volume on the invertebrate fauna of the Ganga river system. The book contains 227 species which were collected and studied by the authors during the last decade. The Mollusca are altogether represented with 108 species, 49 Bivalvia and 59 Gastropoda. The Annelida were recorded with 6 Polychaeta, 70 Oligochaeta and 33 Hirudinida. The Crustacea are included with 11 examples of Branchiopoda, Mysidacea, Amphipoda, Isopoda and few Decapoda crabs. 19 invertebrate species are described new to science. A zoogeographical analysis of the Gangetic basin is given together with a brief discussion of marine elements, brackish water biocoenotic region and certain records of invasive species. The work may be used for identification of species with the help of figures. Instead of using only text descriptions, one can simply compare the invertebrates with the figures to get a first result with the pictorial catalogue. Ecological assessment approach is described with the application of three different indices. 263 pp., 68 (partly col.) pls with 722 figs, br. 4.
