An Ecological Analysis Of Relic Diatoms In Sediments Of Las Vegas Bay, Lake Mead, David Ross Hetzel

Publications (WR)

Relic diatoms in sediments of the inner Las Vegas Bay, near the Las Vegas Wash sewage inflow, were examined in order to assess historic trophic conditions in this area of Lake Mead. Diatom sedimentation rates and ratios of Araphidineae/Centrales (A/C) diatom groups were determined from sediment cores collected in the old wash channel 1.5 km from the sewage inflow (station 2), in a small cove 1.5 km further downstream (station 3) and in an adjacent embayment off Gypsum Wash (station 4). Diatom sedimentation rates generally increased from the bottom to the top of each core, but pronounced minima existed at …

The Temporal And Spatial Distribution Of Hydrocarbons In Atmospheric Deposition From Stations Surrounding Lower Chesapeake Bay, David Benjamin Webber

OES Theses and Dissertations

Hydrocarbon concentrations were determined in bulk, wet, and dry deposition samples from urban and non-urban locations surrounding lower Chesapeake Bay. Mean hydrocarbon concentrations in bulk deposition samples were over three times greater at the urban station indicating a localized source. The major hydrocarbons present were n-alkanes, polycyclic aromatic hydrocarbons (PAH), and the unresolved complex mixture (UCM). The PAH and the UCM were an indication of significant anthropogenic inputs while the odd/even distribution of the n-alkanes was an indication of biogenic sources. These findings indicated seasonal trends of highest biogenic hydrocarbon inputs in the spring and summer months and highest anthropogenic …

A Preliminary Assessment Of Nutrient Loading Into Narragansett Bay Due To Urban Runoff, Lynne Carter Hanson

Marine Affairs Theses and Major Papers

This study is a component of a more comprehensive investigation at the Marine Ecosystems Research Laboratory, (MERL), University of Rhode Island, that was undertaken in order to assess the potential for eutrophication in both its meanings as a natural and man-induced process occurring in the upper portions of Narragansett Bay and its watershed. This assessment required identification and quantification of the various inputs in order to establish the annual loading and eventual effects of the four important nutrients; ammonia, nitrate-nitrite, silicate and phosphate.

Delimitatin Of The Seaward Extent Of United States Jurisdiction Over The Mineral Resources Of Its Continental Shelf, Therese Anne Landry

Marine Affairs Theses and Major Papers

This thesis provides a seaward delimitation of United States jurisdiction over the mineral resources of its continental shelf. It does not set lateral maritime boundaries between the United States and its neighbors. Despite the abundance of literature regarding the continental shelf concept, United States shelf limits have not been demarcated in any precise detail. In order to encourage efficient utilization of offshore mineral resources and to avoid unnecessary legal problems, such determination is important. Initially, the conflicting conceptions of the geological and legal continental shelf are discussed. The evolution of the continental shelf as both a physical feature of the …

The Exploitation Of The Antarctic Oil And Its Environmental And Legal Implications, Renzo Follegati

Marine Affairs Theses and Major Papers

The focus of the paper is the feasible exploitation of the Antarctic offshore oil and the environmental consequences that this fact could have to the whole ecosystem of the Southern Ocean and for other ecosystems of neighboring regions, e.g. the South East Pacific basin. The legal implications that have to do with the exploitation of the Antarctic oil and the regulations that could be applied to preserve the environment are examined.

Report No 56 - 1981 Review Of Rainfall And Wetlands In The South-West Of Western Australia, J. A.K. Lane, D. R. Munro

Fisheries Research Reports

An account is given of the biological principles involved in decisions concerning duck-shooting seasons in the south-west of Western Australia.

The conditions for waterfowl which prevailed during 1981 are described through the use of rainfall statistics and data obtained from the Department's wetland monitoring programme.

Rainfall was generally average over central and northern areas of the south-west during 1981. Rainfall in southern areas, however, was generally

below to much-below-average, although south coastal areas from Augusta to Albany received average falls.

Unusually heavy falls were recorded in North Coastal, North Central and Central Coastal Districts in May, and average falls were …

A Methodology For Siting Coal Fired Thermoelectric Generating Facilities In Puerto Rico, David J. Mcmahon Ii

Marine Affairs Theses and Major Papers

In the past, energy facilities on the Island of Puerto Rico have not been located in the best practicable sites. This is attributable to the absence of mandatory site selection procedures. This thesis has developed and tested procedures for siting 900 MWe coal fired thermoelectric generation plants. The procedures developed here permit the placement of these facilities within the existing legal regime, with a minimum of adverse ecological and socioeconomic impact. The process has been designed to consider the entire Island of Puerto Rico for the suitability of siting a 900 MWe coal fired facility. This is accomplished through the …

A Salt And Water Balance Model For A Silt Loam Soil Cropped To Rice And Soybean, J. T. Gilmour, J. A. Ferguson, B. R. Wells

Arkansas Water Resources Center Technical Reports

A computer model was developed which described salt and water balances for a silt loam soil common to the Grand Praire physiographic region of Arkansas. A ten year period of weather data (1966-75) was used as input data for two divergent cases in regard to salt accumulation. Case one was a rice-soybean rotation with soybean irrigated, while case two was a rice-soybean-soybean rotation with soybean not irrigated. Salts considered were calcium, magnesium, sodium, sulfate and chloride as well as the precipitate, calcium carbonate. Where soybeans were not irrigated less evapotranspiration, more infiltration and less runoff were observed during the fallow …

Radionuclides In Dardanelle Lake In The Area Of The Nuclear I Facility: 1979-1981, D. M. Chittenden Ii

Arkansas Water Resources Center Technical Reports

The variations of the concentrations of 90Sr and 137Cs at four stations in Dardanelle Reservoir were analyzed as functions of two parameters: concentration of ionic species and the activity released, Ar, from the two 900 Mw reactors which use the reservoir as a source of cooling water. Multiple regression analyses were performed on the radionuclide concentrations using the two parameters as predictors. The analyses indicated that 90Sr is in a state of equilibrium between the solution and the suspended sediment. The position of the equilibrium was found to be quite sensitive to changes in the concentration of alkaline earth cations, …

Application Of A New Method For Quantitative Evaluation Of Stream Benthic Algal Populations, Richard L. Meyer, Neil Woomer

Arkansas Water Resources Center Technical Reports

The response of stream biota to changing water quality or other ecosystem perturbations is an important means of assessing water quality. The dynamic nature of streams induces significant sampling and measurement problems. In smaller streams a true algal plankton subcommunity is lacking and the major location for the production of algae is attachment onto stones and other stable surfaces at the substrate-water interface. Several artificial techniques have been developed to analyze the composition of a portion of the epiphytic periphyton (algae attached to stones) but not populations which are qualitatively and quantitatively similar to natural substrates. A newly developed substrate …

Estimating Water Demand Schedules For Selected Industries In Arkansas, Joseph A. Ziegler, Stephen E. Bell

Arkansas Water Resources Center Technical Reports

Water demand functions for the paper and chemical industries in the state of Arkansas were estimated utilizing data collected from individual plants throughout the state. Regression analysis was used to estimate demand functions from a data base which included information on intake and gross water use by source, recirculated water use, costs of acquiring, treating, and discharging water, plant output, employment, and level of technology. The demand for intake water was estimated as an exponential function of average water costs and the level of technology primarily. Price elasticities of demand were estimated as approximately equal to one for both industries. …

Classification And Ranking Of Selectd Arkansas Lakes, Robert E. Babcock, Eugene H. Schmitz, Thomas Buchanan, Richard L. Meyer, James I. Meinecke, David B. Czarnecki

Arkansas Water Resources Center Technical Reports

Trophic-state related problems associated with waters in the United States have generated tremendous public interest and concern, particularly during the past decade. These interests and concerns led to Public Law 92-500, the mandate by Congress known as the Federal Water Pollution Control Act. Various sections of PL 92-500 directly address the need for trophic-state analyses, particularly Section 314 referred to as the Clean Lakes Program which assigns states the responsibility for classifying their lakes according to water quality, identifying methods of pollution control and restoring those lakes which have become degraded.

A Faunal Analysis Of The Springs Of The Ouachita Mountains, Arkansas, Henry W. Robison

Arkansas Water Resources Center Technical Reports

Spring ecosystems in Arkansas have historically received little attention. A faunal survey was made of 33 springs located in the core area Ouachita Mountains physiographic province. The study area was 135 x 80 km extending west from Hot Springs, Arkansas to the Oklahoma line. Springs in the Ouachita Mountain physiographic province were characterized as generally faunistically poor with often a single species such as the isopod, Lirceus h. hoppinae, being the dominant faunal element both numerically and with regard to biomass. A total of 40 species of invertebrate species and eight vertebrate species were collected from the spring environs during …

Water Quality Considerations In The Slurry Pipelining Of Coal, James W. Moore

Arkansas Water Resources Center Technical Reports

Interest in the use of slurry pipelines for the movement of large volumes of coal over long distances has increased rapidly during the last decade. In the early 1970's, this interest involved the movement of Western coals to markets in the southwestern and western United States. In recent years, however, interest in the use of slurry pipelines for transporting Eastern coal developed. Very little information was available concerning the water quality aspects of the slurry pipelining of Eastern coal. The research program was developed to commence building the data base in this regard. Extensive water quality investigations were conducted using …
