The Dilemma Of Dredging And Dredged Material Disposal In The Aquatic Waters Of Rhode Island And Its Impact On The Regional Marina Industry, Darryl J. Keith Jan 1993

The Dilemma Of Dredging And Dredged Material Disposal In The Aquatic Waters Of Rhode Island And Its Impact On The Regional Marina Industry, Darryl J. Keith

Marine Affairs Theses and Major Papers

Since the closures, in 1971, of the Prudence Island and Brenton Reef disposal sites, water-related industries have not had aquatic disposal of dredged sediments as a management option. The marina industry in Rhode Island has been especially impacted as natural sedimentation processes have reduced the water depths at many of these locations and have resulted in the loss of business as operators have been unable to operate their marinas to their fullest potential. The elimination of this option is based on political and environmental concerns over declines in local commercial fisheries which are alleged to be the result of the …


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

Marine Affairs 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 …

Towards A Regional Coastal Zone Management Program In The Oecs, Keith E. Nichols Jan 1993

Towards A Regional Coastal Zone Management Program In The Oecs, Keith E. Nichols

Marine Affairs Theses and Major Papers

The Islands of the Lesser Antilles are described as "truly archipelagic, enjoying the characteristic features of both oceanic and coastal islands." Once considered pristine and far removed from the influences of pollution from coastal areas, they are now faced with the realities of their own solid waste problems, resource degradation and over-exploitation, as well as human health impacts from contaminated rivers and coastal areas. Each of these territories can be considered packages of economic, political and cultural networks, attempting to provide for individual and nationwide needs while seeking economic growth and self-sufficiency. If developed properly and used in tandem with …


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

Marine Affairs 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

Marine Affairs 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 …


Analysis Of Factors Contributing To Environmental Activism: A Case Study Of Beach Clean-Up Participants, Elizabeth Ann Fuller Jan 1993

Analysis Of Factors Contributing To Environmental Activism: A Case Study Of Beach Clean-Up Participants, Elizabeth Ann Fuller

Marine Affairs Theses and Major Papers

This study was initiated to investigate factors which contribute to environmental activism. Towards this end, three hypotheses were investigated. First, it was hypothesized that beach clean-up participants would harbor pro-environmental attitudes. Second, it was hypothesized that participants would be relatively young, politically liberal, well-educated, and wealthy. Finally, it was hypothesized that particular types of social structure would influence a person's decision to participate in a beach clean-up. Specifically, it was hypothesized that participants at each clean-up location would be clique members and/or would be structurally equivalent. Surprising, it was revealed that there was virtually no difference in attitude between the …

Rangeland Monitoring: Analysis, Interpretation, And Evaluation, United States Bureau Of Land Management Jan 1993

Rangeland Monitoring: Analysis, Interpretation, And Evaluation, United States Bureau Of Land Management

All U.S. Government Documents (Utah Regional Depository)

The collection of monitoring data results in quantitative and qualitative information obtained from measurements or estimates of the natural resources. These data are most valuable when their meaning is defined and presented in understandable terms to the resource manager. This is the analysis, interpretation, and evaluation process. The result is the documentation of conclusions on the progress of management to accomplish specific management objectives. Such conclusions are used for management and planning purposes, and in particular, for determining managment actions and establishing new or revised management objectives.


Snapshot In Time, Repeat Photography On The Boise National Forest 1870-1992, United States Department Of Agriculture Jan 1993

Snapshot In Time, Repeat Photography On The Boise National Forest 1870-1992, United States Department Of Agriculture

Forestry

A forest health crisis of unprecedented proportions faced the Boise National Forest in the early years of the 1990's. Six years of drought set the stage for catastrophic outbreaks of insect and disease in the various tree communities of the forest, and wildfires burned hotter and more frequently than at any time in the past. In our often desperate search for ways to moderate the crisis, we turned to the notion of repeat photography to try to understand what happened in the past and how things are different now. We hoped to find some clues that would help shape management …

The Potential Effects Of Climate Change On Summer Season Dairy Cattle Milk Production And Reproduction, Peggy L. Klinedinst, Donald A. Wilhite, G. Leroy Hahn, Kenneth G. Hubbard Jan 1993

The Potential Effects Of Climate Change On Summer Season Dairy Cattle Milk Production And Reproduction, Peggy L. Klinedinst, Donald A. Wilhite, G. Leroy Hahn, Kenneth G. Hubbard

National Drought Mitigation Center: Faculty Publications

The potential direct effects of possible global warming on summer season dairy production and re-production were evaluated for the United States and Europe. Algorithms used for milk production and conception rate were previously developed and validated. Three widely known global circulation models (GISS, GFDL, and UKMO) were used to represent possible scenarios of future climate. Milk production and conception rate declines were highest under the UKMO model scenario and lowest under the GISS model scenario. Predicted declines for the GCM scenarios are generally higher than either “l year in 10” probability-based declines or declines based on the abnormally hot summer …
