Implications Of Soviet And Russian Nuclear Waste Dumping In The Arctic Marine Environment, Jeffrey L. Canfield Jan 1993

Implications Of Soviet And Russian Nuclear Waste Dumping In The Arctic Marine Environment, Jeffrey L. Canfield

Theses and Major Papers

This study examines fragmentary information on ocean dumping of radioactive wastes conducted by the Soviet Union and the Russian Federation from 1959 to the present, then assays the impact of this activity in terms of the legal historical, oceanographic and political contexts. Lacking accurate and thorough data on many aspects of the activity, it has been necessary to infer and extrapolate from what is know about the impact of radioactive materials on analogous ocean sites and regimes where radionuclides have been introduced and monitored by other states. Preliminary assessments are provided for the impact on human uses of resources in …


Nonpoint Source Pollution From Agricultural Runoff: An Analysis Of Problems, Solutions, And The Remedial Action Plan Process For The St. Louis River Basin, Thomas V. Giddings Jan 1993

Nonpoint Source Pollution From Agricultural Runoff: An Analysis Of Problems, Solutions, And The Remedial Action Plan Process For The St. Louis River Basin, Thomas V. Giddings

Theses and Major Papers

Agricultural nonpoint source pollution is the pollution coming from agricultural production, which has no clear origin. It comes from a diffuse source, such as a farm field or an animal holding area. While programs and studies probe every facet of point sources and extol the efforts of point source clean-up, the relatively more difficult task of identifying nonpoint sources and the process of proposing to do something about them has been largely ignored. Reducing the adverse impacts on the environment from farm related activities requires knowledge of the various pollutants and how pollutant pathways can be interrupted. Nutrients, and pesticides …


Conflicts In Use: The Impacts Of The Oil And Gas Industry On The Herring Fishery In The North Sea, Cornelia Ann Pasche Jan 1993

Conflicts In Use: The Impacts Of The Oil And Gas Industry On The Herring Fishery In The North Sea, Cornelia Ann Pasche

Theses and Major Papers

The interaction of the herring (Clupea harengus) with the oil and gas industry in the North Sea is reviewed. The population crash of the herring in the early 1970's and the subsequent closing of that important fishery between 1977 and 1983 has drawn considerable attention to the influences, both biotic and abiotic, affecting the recruitment to the North Sea stock. Current accepted theory points to a change in oceanic current and the subsequent decrease in salinity in the North Sea region, resulting in a change in plankton availability for larval herring as the cause of the recruitment failure during the …


User Perceptions Of The Environmental Quality And Governance System Of Narragansett Bay, Mary-Beth Gadzik Hart Jan 1993

User Perceptions Of The Environmental Quality And Governance System Of Narragansett Bay, Mary-Beth Gadzik Hart

Theses and Major Papers

This paper hypothesizes that there will be differences in perception between the users and managers of Narragansett Bay with respect to (1) the Bay's environmental quality; and (2) the effectiveness of the governance system established to manage and regulate the Bay. Any discrepancies in the perception of the quality of Narragansett Bay's shoreline and water resources among various user groups are likely to contribute to conflicts between users, and a less efficient approach to the management of Bay resources. Thus, the identification of where management policies may diverge from the interests of public user groups will serve to improve resource …
