1978 Water Quality Laboratory services catalog
Linda C. Friedman
1978, Open-File Report 78-502
The information in this catalog is provided to assist field personnel in the selection of determinations, the estimation of costs, the calculation of sample volume requirements, the identification of the necessary sample treatment and in the evaluation of the precision of the laboratory data. The major section of the catalog...
Water-quality records for the Hubbard Creek watershed, Texas, October 1974 - September 1976
Helen J. Davidson
1978, Open-File Report 78-98
The U.S. Geological Survey, in cooperation with the West Central Texas Municipal Water District and the Texas Department of Water Resources, is conducting a continuing program to determine the chemical quality of surface waters in the Hubbard Creek watershed. This report provides a compilation of the records for the period...
Drainage areas of surface water bodies of the Royal and Presumpscot River basins in southwestern Maine
Derrill J. Cowing, J.L. McNelly
1978, Open-File Report 78-556-A
The report contains drainage area values for: lakes and ponds included in the Maine Informational Display Analysis System (MIDAS) File 906-Z, streams that drain an area greater than 25 mi2, dams, and hydrologic data collection sites. Supplemental information in the report includes State and Federal location systems used to identify...
Drainage areas of surface water bodies of the Saco River basin in southwestern Maine
Derrill J. Cowing, Douglas Caracappa
1978, Open-File Report 78-556-B
The report contains drainage area value for: lakes and ponds included in the Maine Informational Display Analysis System (MIDAS) File 906-Z, streams that drain an area greater than 25 mil2, dams, and hydrologic data collection sites. Supplemental information in the report includes State and Federal location systems used to identify...
Estimation of ground motion parameters
David M. Boore, Adolph A. Oliver III, Robert A. Page, William B. Joyner
1978, Open-File Report 78-509
Strong motion data from western North America for earthquakes of magnitude greater than 5 are examined to provide the basis for estimating peak acceleration, velocity, displacement, and duration as a function of distance for three magnitude classes. Data from the San Fernando earthquake are examined to assess the effects of...
High resolution seismic profiles, side scan sonar records, and sampling locations from lower Cook Inlet and Kodiak Shelf, R/V SEA SOUNDER cruise S7-77-WG, September - October, 1977
Arnold H. Bouma, Monty A. Hampton
1978, Open-File Report 78-727
During the period from September 14 through October 10, 1977 the second U.S. Geological Survey geo-environmental cruise was conducted in lower Cook Inlet and on the Kodiak shelf and adjacent upper continental slope, Gulf of Alaska, aboard the R/V SEA SOUNDER (Figure 1, Tables 1, 2 and 3). The objective...
Geochemical explorations for gold deposits at Goldfield, Nevada
Roger P. Ashley, William J. Keith
1978, Open-File Report 78-228
The main problem in geochemical exploration for gold ore bodies in the 40 km2 hydrothermally altered area at Goldfield is to decide which of the many silicified ledges exposed are most likely to yield deposits with additional subsurface exploration. We conclude that the most efficient way to search for exploration...
Hydrologic data for the Antlers aquifer, southeastern Oklahoma
Robert E. Davis, Donald L. Hart Jr.
1978, Open-File Report 78-1038
The U.S. Geological Survey has collected data on Oklahoma's ground-water resources since 1934. Most of these data were collected as part of specific ground-water studies conducted in cooperation with various Federal, State, and local agencies.The information in this report was obtained in the field, from published reports (Davis, 1960, Hart,...
Uranium values from ion-filter water sampling compared with values from bulk-water sampling
Robert Allen Cadigan, J. Karen Felmlee
1978, Open-File Report 78-472
Analytical values of uranium from well water sampled by means of ion-filters were compared with analytical values of the same water sampled by the standard bulk (1-liter) water-sampling technique (Brown, Skougstad and Fishman, 1970). A fluorometric extraction method of analysis was used on both sets of samples. Duplicate samples from...
Exploration geophysics calculator programs for use on Hewlett-Packard models 67 and 97 programmable calculators
David L. Campbell, Raymond D. Watts
1978, Open-File Report 78-815
Program listing, instructions, and example problems are given for 12 programs for the interpretation of geophysical data, for use on Hewlett-Packard models 67 and 97 programmable hand-held calculators. These are (1) gravity anomaly over 2D prism with = 9 vertices--Talwani method; (2) magnetic anomaly (?T, ?V, or ?H) over 2D...
