Proceedings of the sixth conference of the Comité arctique international held in Fairbanks, Alaska, 13-15 May 1985. Subject of conference was: Marine living systems of the far north. Four sections address different aspects of Arctic ecology.

Antarctica is no longer a 'pole apart'. From a scientific perspective, the Antarctic ice sheet, ocean and climate systems are intimately linked with the global climate and are now seen to be of international significance for understanding climate change. From an economic perspective, the Antarctic is perceived to have great potential as a source of marine resources although the extent of speculated mineral and hydrocarbon resources is unknown. From a conservation perspective, the continent of Antarctica represents the ideal image of unspoiled wilderness. Antarctic Environments and Resources is an accessible and timely new geography of the Antarctic which examines the differing and sometimes conflicting interests in the great southern continent, the Southern Ocean and the subantarctic islands against a background of the physical and natural systems of the region and their interactions. It charts the development of human involvement in the area, focusing on the exploitation of resources from early sealing to modern fisheries, tourism and science, and it assesses the consequent impacts on the natural environment. The text also reviews the emerging framework for future environmental management developed under the Antarctic Treaty System. This is an ideal text for undergraduates studying glacial geomorphology, environmental management, polar regions and the Antarctic.

This book discusses the striking geomorphological landscapes of mainland Norway. As part of the Springer book series on World Geomorphological Landscapes, it outlines the nature and diversity of Norway's geomorphological landscapes and examines the geological background and the drivers of landscape evolution. It also features numerous case studies describing the most striking sites, and offers insights into the status and value of geoheritage and geoconservation in the country. Providing readers with an opportunity to explore the variety of Norwegian landscapes and landforms through informative texts richly illustrated with color maps and photos, the book will appeal to scientists, scholars and any readers interested in geology, physical geography, geomorphology, landscape tourism, geoheritage and environmental protection.

The flux, preservation, and accumulation of organic carbon in marine systems are controlled by various mechanisms including primary p- duction of the surface water, supply of terrigenous organic matter from the surrounding continents, biogeochemical processes in the water column and at the seafloor, and sedimentation rate. For the world's oceans, phytoplankton productivity is by far the largest organic carbon 9 source, estimated to be about 30 to 50 Gt (10 tonnes) per year (Berger et al. 1989; Hedges and Keil 1995). By comparison, rivers contribute -1 about 0. 15 to 0. 23 Gt y of particulate organi.

Contaminants in Fish and Sediments in North Atlantic Ocean

This title presents the systematization and description of accumulated knowledge on oceanic fronts of the Norwegian, Greenland, Barents and Bering Seas. The main fronts of the Norwegian, Greenland and Barents Seas are part of the climatic North Polar Frontal Zone (NPFZ). The work is based on numerous observational data, collected by the authors during special sea experiments directed at the investigation of physical processes and phenomena inside certain parts of the NPFZ and in the northern part of the Bering Sea, on archive data of the USSR Hydrometeocenter and other research institutions, as well as on a wide scientific literature published in Russian and Western editions. The book contains general information on the oceanic fronts of the Subarctic Seas, brief history of their investigation, state of the knowledge, as well as detailed description of the thermohaline structure of all frontal zones in the Norwegian, Greenland, Barents and Bering Seas and of neighboring fronts of Arctic and coastal origin. Special attention is given to the study of the multifrontal character of the NPFZ and of peculiarities of its internal structure at different locations, to the description of diverse oceanic features observed in the NPFZ, as well as to some characteristics of the horizontal and vertical fine structure of hydrophysical fields in the NPFZ. The main features of the northern Bering Sea's summer ecohydrodynamics are investigated with the help of three-dimensional direct and inverse models.
