1990, Circular 1046
The Ugashik, Bristol Bay, and western part of Karluk quadrangles (1:250,000) are a part of the Alaska Peninsula in southwestern Alaska. This circular, in conjunction with a companion folio of MF-series maps, two I-series geologic maps, and three bulletins, represents the results of integrated field and laboratory studies on the...
Safe disposal of radionuclides in low-level radioactive-waste repository sites; Low-level radioactive-waste disposal workshop, U.S. Geological Survey, July 11-16, 1987, Big Bear Lake, Calif., Proceedings
Marion S. Bedinger, Peter R. Stevens, editor(s)
1990, Circular 1036
In the United States, low-level radioactive waste is disposed by shallow-land burial. Low-level radioactive waste generated by non-Federal facilities has been buried at six commercially operated sites; low-level radioactive waste generated by Federal facilities has been buried at eight major and several minor Federally operated sites (fig. 1). Generally, low-level...
Effects of surface coal mining and reclamation on the geohydrology of six small watersheds in West-Central Indiana
Jeffrey D. Martin, Richard F. Duwelius, Charles G. Crawford
1990, Water Supply Paper 2368-B
Six small watersheds in west-central Indiana were selected for study of the hydrologic effects of surface coal mining and reclamation. The watersheds include mined and reclaimed, mined and unreclaimed, and unmined agricultural land uses and are each less than 3 square miles in area. Surface-water, ground-water, and meteorologic data for...

Magnetic models for the United States for 1985
Norman W. Peddie, Audronis K. Zunde
1990, Circular 1039
New models describing the magnetic field in the United States at the beginning of 1985 and the rate of change expected during the next few years have been developed. The models--which will serve as the basis for a new set of magnetic charts--were derived from several tens of thousands of...
Coal resources available for development; a methodology and pilot study
Jane R. Eggleston, M. Devereux Carter, James C. Cobb
1990, Circular 1055
Coal accounts for a major portion of our Nation's energy supply in projections for the future. A demonstrated reserve base of more than 475 billion short tons, as the Department of Energy currently estimates, indicates that, on the basis of today's rate of consumption, the United States has enough coal...

Description of the physical environment and coal-mining history of west-central Indiana, with emphasis on six small watersheds
Jeffrey D. Martin, Charles G. Crawford, Richard F. Duwelius, Danny E. Renn
1990, Water Supply Paper 2368-A
This report describes the physical and human environment and coal-mining history of west-central Indiana, with emphasis on six small watersheds selected for study of the hydrologic effects of surface coal mining. The report summarizes information on the geology, geomorphology, soils, climate, hydrology, water use, land use, population, and coal-mining history...
An enhanced digital line graph design

Stephen C. Guptill, editor(s)
1990, Circular 1048
In response to increasing information demands on its digital cartographic data, the U.S. Geological Survey has designed an enhanced version of the Digital Line Graph, termed Digital Line Graph - Enhanced (DLG-E). In the DLG-E model, the phenomena represented by geographic and cartographic data are termed entities. Entities represent individual...
Chemistry and mineralogy of natural bitumens and heavy oils and their reservoir rocks from the United States, Canada, Trinidad and Tobago, and Venezuela

1990, Circular 1047
Twenty-one samples from natural bitumen and heavy oil deposits in seven States of the United States and six samples from outside the United States form the basis of this initial study. This Circular gives the mineral content of the reservoir rock, the trace-element distribution in the reservoir rock and hydrocarbons,...

Applicability of ambient toxicity testing to national or regional water-quality assessment
John F. Elder
1990, Circular 1049
Comprehensive assessment of the quality of natural waters requires a multifaceted approach. Descriptions of existing conditions may be achieved by various kinds of chemical and hydrologic analyses, whereas information about the effects of such conditions on living organisms depends on biological monitoring. Toxicity testing is one type of biological monitoring...
