Tilt networks of Mount Shasta and Lassen Peak, California
Daniel Dzurisin, Daniel J. Johnson, T.L. Murray, Barbara Myers
1982, Open-File Report 82-670
In response to recent eruptions at Mount St. Helens and with support from the USGS Volcanic Hazards Program, the Cascades Volcano Observatory (CVO) has initiated a program to monitor all potentially-active volcanoes of the Cascade Range. As part of that effort, we installed tilt networks and obtained baseline measurements at...
Ground-water levels in selected well fields and in west-central Florida, May 1982
G. L. Barr
1982, Open-File Report 82-867
The water table in the surficial aquifer and the potentiometric surface of the Floridan aquifer in a 1,700-square-mile area in west-central Florida are mapped semiannually by the U.S. Geological Survey. Maps are based on water levels measured in wells each May to coincide with the seasonal low levels and each...
Estimated oil and gas reserves, Gulf of Mexico Outer Continental Shelf and Continental Slope, December 31, 1981
Jack E. Hewitt, Jeff P. Brooke, John H. Knipmeyer, R.M. Surcouf
1982, Open-File Report 82-34
Remaining recoverable reserves of oil* and gas in the Gulf of Mexico Outer Continental Shelf and Continental Slope have been estimated to be about 2.90 billion barrels of oil and 39.8 trillion cubic feet of gas, as of December 31, 1981. These reserves are recoverable from 445 studied fields under...
Lode gold and silver occurrences in Alaska
Edward H. Cobb
1982, Open-File Report 82-406
The following references give data, as of September 1, 1981, on localities where lode gold or silver has been found and are keyed to locations shown on the accompanying map. An asterisk (*) preceding a locality name indicates recorded production. In most instances the report(s) cited for each occurrence is...
Landsat monitoring of albedo changes in northwestern Arizona, 1977-1980
Charles Joseph Robinove
1982, Open-File Report 82-14
As part of a cooperative project between the U.S. Geological Survey and the Bureau of Land Management, changes in albedo (percentage of light reflected from the ground) were calculated and mapped from Landsat images for an area in northwestern Arizona for three periods: August 26, 1977, to September 3, 1979;...
Proceedings, Illinois water-data-users meeting
L. G. Toler (compiler)
1982, Open-File Report 82-1001
The increased demand for water and concern for the quality of the water resources of Illinois have lead to increased demand for water-resources data. Representatives of the major water-data-collecting and water-data-using agencies met in Peoria, Illinois, on February 23-24, 1982, to (1) exchange information on current water-data programs and needs;...
Plankton studies in San Francisco Bay; IV, Phytoplankton abundance and species composition, January 1980 - February 1981
R.L. Wong, J. E. Cloern
1982, Open-File Report 82-443
Data are presented on the phytoplankton species composition and abundance in San Francisco Bay from January 1980 through February 1981. Phytoplankton were identified and enumerated in surface samples collected approximately every two weeks at selected stations in the main channel of the Bay, and at shoal stations in the central...
Ground-water levels in Arkansas, spring 1982
Joe Edds
1982, Open-File Report 82-852
The report contains about 640 ground-water level measurements made in observation wells in Arkansas in the spring of 1982. In addition, the report contains potentiometric-surface maps and well hydrographs relating to the alluvial aquifer and the Sparta Sand, the most important aquifers with respect to ground-water availability and use in...
High-resolution seismic-reflection profiles and sidescan-sonar records collected on Block Island Sound by U.S. Geological Survey, R/V ASTERIAS, cruise AST 81-2
S. W. Needell, R. S. Lewis
1982, Open-File Report 82-322
Cruise AST 81-2 was conducted aboard the R/V ASTERIAS during September 10-18, 1981, in Block Island Sound by the U.S. Geological Survey. It was funded in part by the Connecticut Geological and Natural History Survey. The purpose of the study was to define and map the geology and shallow structure,...
High-resolution seismic-reflection profiles collected aboard R/V James M. Gilliss Cruise GS-7903-3, over the Atlantic Continental Slope and Rise off New England
Norman G. Bailey, John M. Aaron
1982, Open-File Report 82-718
During June 1979, the U.S. Geological Survey (USGS) collected 4,032 km of single-channel seismic-reflection data from the Atlantic Continental Slope and Rise off New England. The work was conducted aboard R/V JAMES M. GILLISS (cruise GS-7903-3). The purpose of the cruise was to determine the characteristics of mass sediment movement...
Guidelines and techniques for obtaining water samples that accurately represent the water chemistry of an aquifer
Hans C. Claassen
1982, Open-File Report 82-1024
Obtaining ground-water samples that accurately represent the water chemistry of an aquifer is a complex task. Before a ground-water sampling program can be started, an understanding of the kind of chemical data needed and the potential changes in water chemistry resulting from various drilling, well-completion, and sampling techniques is needed....
