The National Marine Fisheries Service (NMFS) employs many fishery scientists with diverse skills. The agency finds that the supply of fishery biologists is adequate to meet most of its demand. However, increasing demands on the agency to understand fish populations and the social and economic conditions in fishing communities have created a need for additional experts in the fields of fisheries stock assessment and social sciences. NMFS has de...

As appreciation of the interdisciplinary and multidimensional character of environmental issues has increased, there have been attempts to address regional needs more directly. One of these, the Regional Marine Research Program (RMRP), was established by Congress in 1990 to provide a mechanism to fund coastal marine research based on regionally-defined priorities. The RMRP legislation established a system of nine regional marine research board...

Although the ocean-and the resources within-seem limitless, there is clear evidence that human impacts such as overfishing, habitat destruction, and pollution disrupt marine ecosystems and threaten the long-term productivity of the seas. Declining yields in many fisheries and decay of treasured marine habitats, such as coral reefs, has heightened interest in establishing a comprehensive system of marine protected areas (MPAs)-areas designated ...

Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public.Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stres...

Most U.S. fish stocks are fully or over-exploited, and harvesting in many fisheries far exceeds sustainable levels. The individual fishing quota (IFQ) is a relatively new instrument under which harvesting privileges are allocated to individual fishermen -- innovative yet controversial because of its feared effect on fishing communities and individual fishermen.Based on testimony from fishermen, regulators, environmentalists, and others, Sharin...

During recent years, large-scale investigations into global climate change and other highly visible issues have taken the lion's share of declining research funds. At the same time, funding for basic research in such core disciplines as physical oceanography, biological oceanography, chemical oceanography, and marine geology has dwindled.Depths of Knowledge examines how the largest U.S. ocean research programs, such as the Ocean Drilling Progr...

Environmental information is important for successful planning and execution of naval operations. This title examines the issues such as: how environmental data are used in mine warfare doctrine, and the capabilities of the Navy's oceanographic community to provide supporting information for mine warfare operations.
