An Analysis Of East Pond And The Serpentine Watersheds In Relation To Water Quality, Problems In Environmental Science Course (Biology 493), Colby College, Colby College

Colby College Watershed Study: East and North Ponds (2011, 1999, 1996, 1991)

The Belgrade Lakes in central Maine are important local ecological and recreational resources. The belgrade chain includes the following lakes: East Pond, North Pond, Great Pond, Long Pond, Salmon Lake and Messalonskee Lake. These lakes are all interconnected within the system driving into the Kennebec River through the Messalonskee Stream (Garrity and Putnam, 1971). East Pond is the first lake in the lake chain and it plays a pivotal role in influencing subsequent lakes. Therefore, the water quality of this lake is important not only to East Pond residents but to the residents of the entire lakes region.

Mariculture Management For Pohnpei State, Federated States Of Micronesia, Kevin Brooks Foster

Marine Affairs Theses and Major Papers

The Marine Resources Division of Pohnpei State, Federated States of Micronesia is currently engaged in development activities that include the establishment of family scale mariculture projects for community members of remote villages and outer islands. The goal of this undertaking is to supplement subsistence and income generation ventures for community members through the wise use and exploitation of the marine environment. These aims may be jeopardized unless a management plan is devised that reflects the customary marine resource practices as embraced by islanders from each community. The intent of this thesis projects is to devise a mariculture management model that …

Impacts Of The Unclos Iii Consent Regime On U. S. Marine Scientific Research, 1982-1989, Matthew Patrick Murphy

Marine Affairs Theses and Major Papers

The 1982 Conference on the Law of the Sea (UNCLOS III) has given states jurisdiction over unprecedented scopes of ocean space. Marine scientific research is among the activities under coastal state control. This thesis examines five possible areas of impact of coastal state control on United States research programs. These are: 1. research which was denied outright, 2. reasons for denials, 3. research which was delayed, 4. the extent to which researchers avoid requests in the waters of restrictive states, and 5. the level of interest among UNOLS institutions in cooperative arrangements with foreign governments. The international legal framework for …

Alyeska, Sullom Voe And The Oil Pollution Act Of 1990: A Comparison Of Tanker Safety Regulation And Environmental Monitoring, Neil V. Kelly

Marine Affairs Theses and Major Papers

The Exxon Valdez oil spill in 1989 highlighted deficiencies in the Trans Alaska Pipeline System's (TAPS) marine operation on both regulatory and operational levels. The United States Congress passed the Oil Pollution Act of 1990 to promote the prevention of oil spills and to improve our ability to mitigate the effects of spills that occur. An oil terminal roughly analogous to the TAPS terminal at Valdez, Alaska, exists at Sullom Voe in the Shetland Islands, west of Norway and to the north of Scotland in the North Sea. The Sullom Voe terminal has had an environmental advisory group guiding policy …

Windbreaks And Wildlife, Ron J. Johnson, Mary M. Beck, James R. Brandle

School of Natural Resources: Faculty Publications

Windbreaks can support wildlife that add beauty and pleasure to our lives. They also sustain birds that eat insect pests, improve hunting opportunities, and provide a focal point for family outdoor activities. The world around us would be less appealing without the stimulation - the color, sounds, tracks, and mystery - of wild creatures; windbreaks help wildlife and in some areas are essential to survival of the wildlife we enjoy. You can add wildlife benefits to windbreak plantings whether your main goal is to shelter crops, livestock, + roads, or a home or farmstead.

Modeling Age-Specific Mortality For Marine Mammal Populations, Jay Barlow, Peter Boveng

United States Department of Commerce: Staff Publications

A method is presented for estimating age-specific mortality based on minimal information: a model life table and an estimate of longevity. This approach uses expected patterns of mammalian survivorship to define a general model of age-specific mortality rates. One such model life table is based on data for northern fur seals (Callorhinus ursinus) using Siler’s (1979) 5-parameter competing risk model. Alternative model life tables are based on historical data for human females and on a published model for Old World monkeys. Survival rates for a marine mammal species are then calculated by scaling these models by the longevity …

Assessment Of Organic And Metal Contaminants In Lower Back Bay And Upper Currituck Sound, Kate Benkert

V. Poster Abstracts

Studies were conducted at Mackay Island National Wildlife Refuge in 1988 and 1989 to provide baseline data for an assessment of organic chemicals and metal contaminants in the aquatic ecosystem. Longnose gar, gizzard shad, snapping turtles, common rangia clams and sediments were collected from sites in lower Back Bay and upper Currituck Sound for contaminant analyses.

Composite sediment samples were analyzed for the presence of metals, organochlorine pesticides and polycyclic aromatic hydrocarbons (PAHs). Organochlorine pesticides were not detected in the sediments. Various PAH compounds were detected in the sediments, although at trace concentrations which just exceeded the analytical detection limit …

Refuge Land Acquisition: Helping Preserve Back Bay's Wildlife Heritage, Julia Herrick, Ben Mathias, Janet Taylor

V. Poster Abstracts

The once-renowned waterfowl populations and bass fishery of Back Bay, Virginia have declined dramatically in recent years. Lands surrounding Back Bay are increasingly threatened by on-going and potential land development. These lands serve as an important filter for pollutant and sediment-laden runoff from adjacent areas. The boundary of the Back Bay National Wildlife Refuge was expanded in 1989 to include an additional 6,340 acres of brackish marsh, forested swamp, and "critical edge" upland habitat, important to a variety of wildlife species and for its natural filtering effect. Within the U.S. Fish and Wildlife Service's policy of working with willing sellers, …

13.1.3. Life History Strategies And Habitat Needs Of The Northern Pintail, Leigh H. Fredrickson, Mickey E. Heitmeyer

Waterfowl Management Handbook

The northern pintail (hereafter pintail) is a common dabbling duck distributed throughout the Northern Hemisphere. Since 1955, the breeding population in North America has averaged 5,566,000, fluctuating between 10,124,000 (1956) and 2,471,000 (1989; Fig. 1). Pintail numbers are especially sensitive to habitat conditions that reflect the wet–dry cycle in the shortgrass prairie breeding areas of south-central Canada and the northern Great Plains of the United States. Populations of pintails also are affected by habitat conditions in key wintering areas, such as the Central Valley of California and Gulf Coast marshes. When wintering areas are fairly dry, birds have fewer resources …

Predation Risk And The Importance Of Cover For Juvenile Rainbow Trout In Lentic Systems, R. A. Tabor, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Juvenile rainbow trout Oncorhynchus mykiss stocked in midelevation reservoirs in Utah inhabit shallow nearshore areas and are vulnerable to predation from piscivorous fish and birds. We determined the use and importance of nearshore habitats by (1) measuring habitat selection by, prey availability to, and feeding of juvenile rainbow trout in two reservoirs with populations of predators, and (2) measuring survival and growth rates in the presence and absence of cover in a pond experiment where adult brown trout Salmo trutta were predators. In the reservoirs juvenile rainbow trout (60–120 mm standard length) were abundant in complex inshore habitats but avoided …

Remnant Vegetation On Farms Is A Valuable Resource, Richard Hobbs, Ken Wallace

Journal of the Department of Agriculture, Western Australia, Series 4

Retention of native vegetation on farms is important both from an ecological and an economic point of view. Productivity in the paddocks ultimately will depend on the retention and replacement of trees and shrubs in the landscape. Remnants of native vegetation can play their part by helping to ensure the long-term viability of the agricultural system, as well as greatly enhancing the quality of life for those living on the land.

Size Classification Of Bed Sediment And Selection Of Resuspension Monitoring Sites In Upper Tampa Bay, Florida, David H. Schoellhamer, Southwest Florida Water Management District (Sfwmd), City Of Tampa, City Of St. Petersburg, Hillsborough County, Pinellas County, Tampa Port Authority

Reports

The size classification of surficial bed sediments in upper Tampa Bay, Florida, including Hillsborough Bay, Old Tampa Bay, and middle Tampa Bay south of the Interbay Peninsu la, was determined during 1987-89. Fathometer transects were performed throughout the study area to determine the reflective characteristics of the bed, and grab samples were collected to relate the fathometer data to size classifications of sediments. The data collected during this study indicate that fine bed sediments are most abundant in Hillsborough Bay and least abundant in the southern part of the study area closest to the mouth of Tampa Bay. Generally, the …

A Study Of Periphyton, Sediment And Diatom Community Structure As Monitors Of Heavy Metal Pollution In The Embarras River And Brushy Fork, David L. Vaultonburg

Masters Theses

The purpose of this study was to evaluate periphyton (diatom) and sediment heavy metal content and diatom community structure as potential monitors of heavy metal pollution in the upper reaches of the Embarras River system. The study was initiated due to recent industrialization in the area which could potentially contribute to the present heavy metal burden of Brushy Fork and the Embarras River. These streams are already subject to agricultural runoff, wastewater plant effluent, landfill leachate and other miscellaneous urban and highway runoff. The Embarras River system drains an area of approximately 2800 square miles in 11 east-central Illinois counties …

Studies Related To Nutrients Entering Groundwater From The Heber Valley Sewer Farm And Dairies, Roland W. Jeppson, Joan Mclean, Calvin G. Clyde, Scott Korom

Reports

Foreword: This report includes the results from a two year study in the Heber Valley to determine amounts of nutrients that are entering the groundwaters of the Heber Valley, and might ultimately enter Deer Creek Reservoir. Since Deer Creek Reservoir in Heber Valley, Utah supplies approximately 65 percent of the water distributed to Salt Lake County, the maintenance of its quality is of considerable importance. To maintain the quality of this reservoir and limit its eutrophication "best management" practices for surface water have been implemented gradually during the past decade in Heber Valley. These practices have significantly improved the qualities …
