The secondary effort, Phase II, will estimate seasonal nutrient exchange rates for "sandy" and "muddy" sediments at a minimum of two locations in Hillsborough Bay. The seasonal estimates of sediment nutrient …

Acid Deposition: Legal And Political Controversies, Noelle F. Lewis

Marine Affairs Theses and Major Papers

Acid rain is more accurately referred to as acid deposition since acidity is deposited in both the wet and dry form. Acid rain results from the conversion of sulfur and nitrogen gases to sulfates and nitrates, respectively. In the United States, sulfur compounds are responsible for about two-thirds of the acidity in precipitation; nitrogen compounds, one-third. In 1980, man-made sources in the United States emitted approximately 26 million tons of sulfur dioxide and 21 million tons nitrogen oxides. Within the United States, the major sources of sulfur dioxide emissions, approximately 90-95% of the total, are electric generating utilities, industrial boilers, …

A Review Of The Management And Current Status Of Northern Fur Seals Of The Pribilof Islands, Holly Hansell

Marine Affairs Theses and Major Papers

The North pacific fur seals of Alaska's Pribilof Islands have been subjected to commercial harvest for nearly 200 years. The harvest has been regulated under international agreement almost continuously since 1911; first under the 1911 North Pacific Fur Seal Convention, and following that under the 1957 Interim Convention on Conservation of North Pacific Fur Seals. Both Conventions banned pelagic sealing and divided the restricted land harvest among the four member states, the United States, Canada, Japan, and the Soviet Union. Management under the 1911 convention resulted in a steady increase in the severely depleted fur seal herd, restoring the population …

Analysis Of A Worst Case Oil Spill Eis, Galveston, Gail Elizabeth Meisner

Marine Affairs Theses and Major Papers

On July 8, 1980, the Galveston district of the U.S. Army Corps of Engineers (Corps) issued the permits required for the construction of an onshore deepwater port. The proposed port expansion project has been the subject of extensive controversy and litigation. The primary conflict has centered on the exclusion of a worst case oil spill analysis, as required by recent Council on Environmental Quality (CEQ) regulations. A rational-deductive approach to this decision leads to the conclusion that the economically and environmentally favored choice would have been to include the worst case analysis in the initial Environmental Impact Statement (EIS). Because …

Investigation Of Pollution In A Karst Aquifer Utilizing Optical Brightener, John Thrailkill, Ralph F. Wiseman, Bridget R. Scanlon

KWRRI Research Reports

Optical brightener is an additive to laundry detergents and is found contaminating groundwater. Its concentration may rapidly and inexpensively be determined by fluorescence techniques, and because its source is human wastewater, its presence in groundwater serves as a direct indication of pollution from septic tanks, sewer leaks, and landfills.

A total of 105 wells and springs in an area within the Inner Bluegrass Karst Region near Lexington, Kentucky, were described and sampled. Analyses were made for optical brightener (430 samples), total coliform (91), fecal coliform (93), and fecal streptococci (90). As many as 20 optical brightener and 4 bacterial samples …

Hillsborough Bay Macroalgae Study Final Report, Mangrove Systems, Inc.

Reports

Hillsborough Bay. the northeastern portion of the Tampa Bay estuarine system (Fig. 1) has long suffered from the problems caused by industry and urbanization (Simon 1974). The macroalgal community of this estuary has been identified as a source of nuisance odor problems for many years. A study by the Federal Water Pollution Control Administration (FWPCA 1969) indicated that these problems resulted from degraded water quality (primarily eutrophication) which led to large populations of one or two species of marine red algae (Gracilaria spp.). Seasonal freshwater input resulted in the death and decay of these quantities of algae, producing the odor …

Laverkin Springs, Utah On-Site Pretreatment And Desalting Processes Evaluations, R. J. Eisenhauer, Bureau Of Reclamation

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

During December 1979 through August 1980, pilot plants and laboratory facilities were operated at the LaVerkin Springs, Utah site to characterize the water and to evaluate various pretreatment processes and desalting processes. The pretreatment processes studied included aeration-precipitation, lime treatment, lime-soda ash treatment, and lime-ion exchange treatment. Desalting at 80 and 90 percent water recovery levels was studied with both electrodialysis and high pressure reverse osmosis process equipment. Also, a "spiractor" was evaluated at the site as a lime-soda ash reactor and as a calcium sulfate desupersaturator. Data and results obtained from the test program will be used for feasibility …

Residual Values Of Australian Rock Phosphates, Michael D A Bolland

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

For years superphosphate has been the cheapest, convenient and most effective way of supplying phosphorus to newly cleared soils in Western Australia's South-West that are acutely deficient in phosphorus. However its effectiveness as a phosphorus source falls markedly after application. Regular applications are needed to maintaine profitable pastures and crops on these soils.

After a big jump in supperphosphate prices in the mid 970s, researchers tested the use of Australian rock phosphates as potentially cheaper alternative phosphorus fertilisers to superphosphate. On the none-leaching sands, as this article shows, none of the rock phosphates was as effective for plant growth as …

Ending Subsidized Degradation: The Ocean Dumping Example, Brenda Asher Dillman

Marine Affairs Theses and Major Papers

There is no way to measure, on a global scale, the pollution dumped directly into the oceans, let alone all the tens of thousands of particulates, toxics, and gaseous substances are added each day to the atmosphere surrounding the New York Bight. The aim of this paper is to develop a user fee framework for the ocean dumping of municipal sludge. Such a proposal requires a radical departure from the standards and enforcement approach of today's legislation. The ocean dumping of municipal sludge, while accounting for only a small percentage of the total waste dumped into the Bight, has proven …

A Proposal To Fertilize The Overton Arm And Gregg Basin Areas Of Lake Mead, Larry J. Paulson

Publications (WR)

Several limnological studies have been conducted in Lake Mead during the past decade. The recent studies clearly show that most of Lake Mead is deficient in nutrients, especially phosphorus, and very low in productivity. The reservoir-wide average total phosphorus concentration for 1981 - 1982 was only 9 mg/m³. This is below levels found In most oligotrophic lakes and reservoirs. Algal biomass, as measured by chlorophyll-a, averaged only 1.5 mg/m³. That also places Lake Mead in the oligotrophic range. Transparency, as measured by a Secchi disc, averaged 9-5 m in Lake Mead during 1981-1982. That far exceeds …

Coral Reef Islands And Their Problems, Peter C. Schroeder

Marine Affairs Theses and Major Papers

Small islands and in particular those more or less dependent on their reefs as a resource were often self-contained units, maintaining a fragile equilibrium in which even small changes could and have wrought fatal disturbances. The pressures of the modern world have endangered these vulnerable units economically, socially, and biologically. In all instances the "'population factor has played an important role. Coral reef islands appear to be more susceptible to the side effects of rapidly growing modernization than other types of islands. No clear answer or solution to this problem can be given but recognition of the threats to them …

Seasonal And Spatial Heterogeneity In The Limnetic Zooplankton Community Of Lake Mead, Gene Robert Wilde

Publications (WR)

Zooplankton samples collected from throughout Lake Mead, in 1981-1982, demonstrate the presence of a statistically significant seasonal and spatial heterogeneity in zooplankton densities. Seasonally, the major zooplankton groups were most abundant in the spring and fall, coincident with maxima in chlorophyll-a concentrations. Successions among the various rotifers, cladocerans and copepods present in the reservoir were influenced by food availability, diapause, predation by planktivorous fish and, possibly, water temperatures. Spatial heterogeneity in zooplankton densities was unrelated to water temperature, pH, conductivity and dissolved oxygen concentrations, but was related to the abundance of phytoplankton (chlorophyll-a concentrations) and fish. Statistical analyses indicate that …

The Role Of Nannoplankton In The Phytoplankton Dynamics Of Four Colorado River Reservoirs (Lakes Powell, Mead, Mohave, And Havasu), Jeffrey John Janik

Publications (WR)

Phytoplankton species composition and community size structure were studied in four warm-monomictic Colorado River reservoirs; lakes Powell, Mead, Mohave, and Havasu from March 1981 to February 1982. Sampling was done at approximately monthly intervals from several stations in each reservoir. The Utermohl technique was used to enumerate phytoplankton. The phytoplankton assemblage was divided into the following six size classes using microscopic techniques; netplankton (>64 um), and nannoplankton (>5, 5-11, 12-21, 22-44, and 45-64 um).

Total phytoplankton biomass and community size structure were different among these four reservoirs with considerable spatial and temporal variation present. Average reservoir-wide areal weighted …

Wasteload Allocation Study Tampa Bay, Florida Statistical Study, Peter Gaitho

Reports

This statistical study was carried out on the Tampa Bay area in an effort to establish some basic relationships between levels of chlorophyl A and various environmental factors. Several statistical analyses were carried out. It was decided to use original data rather than averages over several months. It was felt that this would give us more reliable results. At the outset, the study centered around the use of data from only three months during the year; namely, February, June and October. It was felt that these months would be representative of the seasonal difference. Later, all months of the year …

Las Vegas Wash Multispectral Scanner Survey, T. H. Mace, M. V. Olsen, Environmental Protection Agency

Publications (WR)

At the request of the U.S. Bureau of Reclamation, Boulder City, Nevada, the U.S. Environmental Protection Agency's Environmental Monitoring Systems Laboratory at Las Vegas collected multispectral scanner imagery of Las Vegas Wash on October 1, 1982. A combined maximum likelihood classification and editing procedure was used to classify the multispectral scanner imagery into 12 categories of land cover. The classification identified four categories of marsh vegetation, one category of riparian, two categories of mixed scrub, and two desert categories. Turbid water and cultivated land formed an "other" category. Area tabulations were formed by georeferencing the classification to the Universal Transverse …
