Sensitivity Of Vertebrate Embryos To Heavy Metals As A Criterion Of Water Quality, Wesley J. Birge, John J. Just

KWRRI Research Reports

Embryonic and/or larval stages of the leopard frog (Rana pipiens), domestic fowl (Gallus domesticus) and the goldfish (Carassiua auratus) were treated with cadmium chloride, mercuric chloride, lead chloride, zinc chloride and sodium arsenite. The principal objectives were (1) to determine the sensitivity of vertebrate embryos to certain metals which are of consequence in water pollution, and (2) to ascertain the suitalility of vertebrate embryos as bioassay organisms for monitoring metallic pollutants within water resources. Vertebrate embryos are found to be highly sensitive to the toxic effects of all the metals studied. Concentrations of mercury as low as 10 ppb, with …

Nebraska Wild Flowers, Robert C. Lommasson, Paul Lommasson (Depositor)

School of Natural Resources: Faculty Publications

This book is an attempt to present to the general public representative types of many of the conspicuous wild flowers found in Nebraska. These 260-some plants in no way constitute a flora of Nebraska which would number some 1,700 species of flowering plants. Included herein are both native and naturalized flowering herbaceous plants exclusive of the grasses and grasslike plants. Among these are plants that have had a long existence here and others which have recently invaded our area. Some are highly cherished and others are considered as common weeds. Excluded from this book are woody plants, such as trees, …

Journal of the Minnesota Academy of Science

Significant actions taken by the Commissioner, Department of Natural Resources of the State of Minnesota, on recommendations of the Advisory Committee on Scientific and Natural Areas includes: issuance of policy statements and directives establishing criteria for defining and classifying scientific and natural areas; and rules and regulations applicable to such areas. Listed are the first four areas recommended for official designation. The status of an inventory of scientific and natural areas is summarized, and a description is given of the Advisory Committee procedure for processing recommendations for establishment of areas to be officially designated by the state.

A Eutrophication Model Of The White River Basin Above Beaver Reservoir In Northwest Arkansas, Robert A. Gearhart, Dee Mitchell, Louis Thibodeaux, Richard Meyers

Arkansas Water Resources Center Technical Reports

With national interest focused on man’s ever increasing degradation of the waters in this nation, it is clearly evident that an accurate assessment of all parameters influencing water quality needs to be made. Moreover, nutrient levels and budgets reflecting eutrophication trends are important parameters in the overall factors effecting water quality in lakes and reservoirs. The ability to predict future eutrophication levels will greatly enhance the retardation of the eutrophication process. Through mathematical simulation of this process, eutrophication can be analyzed and intelligent decisions regarding water quality management can be made.

Broad Spectrum Microwave Systems For Remotely Measuring Soil Moisture Content, W. P. Waite, K. R. Cook, B. B. Bryan

Arkansas Water Resources Center Technical Reports

A theoretical and experimental study of the microwave reflectivity of soils with varying moisture content was conducted. A system was developed to measure reflectivity over a continuous frequency range of 4 to 26.5 GHz, at incidence angles from 10° to 70°, and with both horizontal and vertical polarization. The measurements were found to be extremely accurate for smooth homogeneous surfaces, however, the effects of surface roughness were found to be more severe than predicted due to the discontinuous nature of naturally occurring rough surfaces. An algorithm was developed which used the frequency dependence of the reflectivity to estimate the effective …

Mathematical Modeling Of Stream Storage Potential, Hugh M. Jeffus

Arkansas Water Resources Center Technical Reports

Streamflow data from unregulated streams in Arkansas were processed through Moran’s Model for a dam. The process involved calculating a cumulative gamma distribution for each stream as the streamflow values were incremented in units of 0.1 cubic feet per second per square mile of drainage area. This gamma distribution was then used as input for Moran’s Model. The output from Moran's Model includes the probability of the reservoir having zero contents as the size of the reservoir is decreased. The logarithm of the probability of zero contents, 1n PO, versus reservoir size, K, is a straight line of the form …

Offshore Oil Interests Of The United States: An Overview, Scott H. Marstan

Marine Affairs Theses and Major Papers

The following discussion focuses on the current situation as regards U.S. oil interests worldwide offshore. It divides into three general areas: 1) a general view of the scope of the U.S. oil companies' investments offshore, foreign and domestic, 2) an analysis of the recent rise to power of the Organization of Petroleum Exporting Countries (OPEC) and the ensuing problems created for U.S. oil investments abroad, and 3) a brief history and a discussion of U.S. oil interests in the law of the sea as an expression of their concern for resolution to OPEC-like problems.

Environmental Improvement: A Concept For Harbor Maintenance Programs For Long Island Sound, John-Robert Curtin

Marine Affairs Theses and Major Papers

This paper suggests a comprehensive approach to maintenance dredging and maintenance dredge disposal for Connecticut in a carefully-regulated manner that will improve, rather than impair, the natural quality of the Sound. It proposes an interim measure that would allow for the continued operation of Connecticuts Commercial Harbor areas until a permanent program, together with the necessary technological advances, can be implemented to handle dredge disposal. This paper is based on data presently available on New Haven Harbor, presented in a report on the environmental quality of dredge spoils proposed to be removed from one area within New Haven Harbor known …

Animal Damage Control In South Dakota, V. Van Ballenberghe

Great Plains Wildlife Damage Control Workshop Proceedings

South Dakota, like virtually all other states, is subject to economic losses from wildlife depredations. We have been in the government sponsored, animal damage control business perhaps longer than some states - our history dates back to the time of Three-toes and the Custer Wolf. In 1973 we are still in that business, perhaps more intensively than ever before, and we regard animal damage control as one of the most pervasive and difficult to solve wildlife problems facing us.

The Missouri River bisects South Dakota into approximately equal "East River" and "West River" land areas. These differ ecologically, and to …

Crayfish, Leech, And Snail Control

Great Plains Wildlife Damage Control Workshop Proceedings

We have effective results in controlling crayfish in our ponds using Baytex. Baytex is a higly toxic compound that effects the nervous system of many organisms. Used in small concentrations it will kill crayfish without hurting fish. We use Baytex at 40 ppb. We normally dilute the required amount of chemical with water and then mix it thoroughly in the pond. Leeches can be controlled using Dylox. Masoten is another trade name for dylox. The recommended rate of application is 1/2 ppm. This should be applied in a manner so it is thoroughly mixed in the ground. Recommened treatment for …

A Study To Improve Dissolved Oxygen Analysis Techniques To Facilitate Water Quality Field Survey Applications, R. W. Raible, M. K. Testerman

Arkansas Water Resources Center Technical Reports

This report describes studies made of the temperature characteristics of dissolved oxygen electrodes having a large surface area. Large area electrodes proved to have much longer lifetime between rejuvenations. Many measurements of dissolved oxygen in water need to be made in field situations where recalibration techniques would be difficult and where making temperature corrections is time consuming for operators who may be making numerous measurements. This study was directed toward design of a compensation circuit for a dissolved oxygen electrode which will give the best possible measurement over a large water temperature range of 5° - 35°C without the necessity …
