A practical framework for river-quality assessment
David A. Rickert, Walter G. Hines
1975, Circular 715-A
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Water temperature-influential factors, field measurement, and data presentation
Herbert H. Stevens, John F. Ficke, George F. Smoot
1975, Techniques of Water-Resources Investigations 01-D1
This manual contains suggested procedures for collecting and reporting of water-temperature data on streams, lakes and reservoirs, estuaries, and ground water. Among the topics discussed are the selection of equipment and measuring sites, objectives and accuracy of measurements, and data processing and presentation. Background information on the influence...
Mineral resource management of the Outer Continental Shelf : leasing procedures, evaluation of resources, and supervision of production operations on leased lands of the Outer Continental Shelf
Maurice V. Adams, C.B. John, R.F. Kelly, A.E. LaPointe, R.W. Meurer
1975, Circular 720
An important function of the Geological Survey is the evaluation and management of the mineral resources of the Outer Continental Shelf, particularly with respect to oil and gas, salt, and sulfur. Production of oil and gas from the Outer Continental Shelf of the United States has increased substantially over the...
Anomalous concentrations of several metals in iron-formation of the Blue Lead Mountain area, Pennington County, South Dakota
William H. Raymond, Robert Ugstad King, James Jennings Norton
1975, Circular 707
Geochemical sampling of bedrock has revealed anomalous copper, silver, molybdenum, gold, arsenic, mercury, zinc, and cobalt in meta-iron-formation in the Blue Lead Mountain area 5 miles (8 kilometres) north-northwest of Keystone, S. Dak. The anomalies are in complexly folded and faulted iron-formation. Metal content decreases sharply in the surrounding rocks....
In search of a statistical probability model for petroleum-resource assessment : a critique of the probabilistic significance of certain concepts and methods used in petroleum-resource assessment : to that end, a probabilistic model is sketched
Bernardo F. Grossling
1975, Circular 724
Exploratory drilling is still in incipient or youthful stages in those areas of the world where the bulk of the potential petroleum resources is yet to be discovered. Methods of assessing resources from projections based on historical production and reserve data are limited to mature areas. For most of the...
Low-flow Characteristics of Eau Claire River Basin near Antigo, Wisconsin
B. K. Holmstrom
1975, Open-File Report 75-336
This report presents low-flow characteristics at six sites on streams in the Eau Claire River basin near Antigo, Wis., where applications for irrigation permits were made. The low-flow characteristics presented are the annual minimum 7-day mean flows at the 2-year recurrence interval and 10-year recurrence interval. A seepage run made...
Geologic framework of the Alaskan Continental Terrace in the Chukchi and Beaufort seas
Arthur Grantz, Mark L. Holmes, B. A. Kososki
1975, Open-File Report 75-124
Seismic, magnetic and gravity data indicate that the Chukchi and Beaufort epicontinental seas off northern Alaska overlie three sedimentary basins, or provinces, separated by structural highs of regional extent. The basins trend west to northwest and become increasingly marine from south to north. The Chukchi-Beaufort continental margin is similar to...
