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.

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.

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.

Fish recruitment is a key process for maintaining sustainable fish populations. In the marine environment, fish recruitment is carried out in many different ways, all of which have different life history strategies. The objective of this book is to argue for greater linkages between basic and applied research on fisheries recruitment, and assessment and management of exploited fish stocks. Following an introductory chapter, this second edition of Fish Reproductive Biology is organized into 3 main sections: Biology, Population Dynamics and Recruitment Information Critical to Successful Assessment and Management Incorporation of Reproductive Biology and Recruitment Considerations into Management Advice and Strategies The authors collectively bring a wide range of diverse experience in areas of reproductive biology, fisheries oceanography, stock assessment, and management. Fully updated throughout, the book will be of great interest to a wide audience. It is useful as a textbook in graduate and undergraduate courses in fisheries biology, fisheries science, and fisheries resource management and will provide vital information for fish biologists, fisheries scientists and managers.

This is the first book to provide assessments of multidecadal changes in resources and environments of the Large Marine Ecosystems (LMEs) of the North Atlantic. Using the case study method, researchers examine the forces driving the changes and actions underway aimed at turning the corner from declining trends in biomass yields, toward recovery of depleted species populations and improvements in ecosystem integrity. Recently a distinguished group of 24 scientists argued eloquently that a new Sustainability Science was emerging that was focused on "meeting fundamental human needs while preserving the life support systems of planet Earth". The contributions contained in this volume are at the cutting edge of Sustainability Science and the results presented by the contributors are pertinent to one of the core questions: "How are long-term trends in environment and development, including consumption and population, reshaping nature-society interactions in ways relevant to sustainability?" (Science Vol. 292, 27 April 2001). The case studies demonstrate the utility of an ecosystem-based approach to the assessment and management of biomass yields and species sustainability. Movements toward ecosystem-based management have emerged from the case studies on the initiation of recoveries of several depleted groundfish stocks of the US Northeast Shelf LME; the collapse of the Newfoundland-Labrador Shelf cod; the assessment of physical and biological changes on the Scotian Shelf, West Greenland Shelf, Iceland Shelf LME, and the Faroe Plateau, the North Sea, and the Barents Sea LMEs. Uncertainties, with regard to environmental and human-generated forcing, are addressed in assessment of the states of the Iberian Coastal and Biscay-Celtic LMEs, and in broad-scale studies of the influences at the base of the food chain of climatic variability on the productivity and biodiversity of plankton communities of the North Atlantic. The volume concludes with an insightful perspective on the approaches used and the results reported by the eminent marine scientist and former President of ICES, Professor Gotthilf Hempel.

This book identifies accumulated environmental, social and economic effects of oil and gas leasing, exploration, and production on Alaska's North Slope. Economic benefits to the region have been accompanied by effects of the roads, infrastructure and activies of oil and gas production on the terrain, plants, animals and peoples of the North Slope. While attempts by the oil industry and regulatory agencies have reduced many of the environmental effects, they have not been eliminated. The book makes recommendations for further environmental research related to environmental effects.

Oceans and Aquatic Ecosystems theme is a component of Encyclopedia of Natural Resources Policy and Management, in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The theme guides the reader through various pathways followed by surface water on earth. It describes the dominant processes that govern how organisms interact with water and with each other, and how they in turn can modify water properties. This knowledge is important for humanity. Indeed, only by understanding our actions impacts upon water, and the animals and plants living in it, can we learn to exploit water, marine and fresh-water habitats and the living organisms, without destroying the resources on which our livelihood and very survival depend. The Theme on Oceans and Aquatic Ecosystems discusses matters of great relevance to our world such as: Freshwater Wetland Resources and Biology; Problems, Restoration and Conservation of Lakes and Rivers; Coastal Regions; The Oceans and Seas; Oceanic Islands These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
