A U.S. Geological Survey Data Standard (Specifications for representation of geographic point locations for information interchange)
Water Resources Division, U.S. Geological Survey
1983, Circular 878-B
This standard establishes uniform formats for geographic point location data. Geographic point location refers to the use of a coordinate system to define the position of a point that may be on, above, or below the Earth's surface. It provides a means for representing these data in digital form for...
Floods from small drainage basins in Alaska
Stanley H. Jones
1983, Open-File Report 83-258
Flood peak-stage and associated discharge data collected since 1963 in small (generally less than 100 square miles) drainage areas in Alaska are presented in tabular and graphical form. The report also contains table of computed magnitudes of floods at selected recurrence intervals (2, 5, 10, 25, and 50 years) for...
Assessment of gray whale feeding grounds and sea floor interaction in the northeastern Bering Sea
C.H. Nelson, K.R. Johnson, John H. Barber
1983, Open-File Report 83-727
A dense ampeliscid amphipod community in Chirikov Basin and around St. Lawrence Island in the northeastern Bering Sea has been outlined by summarizing biological studies, analyzing bioturbation in sediment samples, and examining sea floor photos and videotapes. The amphipod population is associated with a homogeneous, relict fine-grained sand body 0.10-1.5...
Preliminary stage-discharge relations for Tombigbee River at Aliceville lock and dam, near Pickensville, Alabama
G. H. Nelson, C. O. Ming
1983, Open-File Report 83-752
The construction of Aliceville lock and dam and other related channel alterations, completed in 1979, has resulted in changes to the stage-discharge relations in the vicinity. The scarcity of current-meter measurements, coupled with backwater conditions, makes definition of a single stage-discharge relation impossible. However, limit curves can be defined that...
Rock property measurements and analysis of selected igneous, sedimentary, and metamorphic rocks from worldwide localities
Gordon R. Johnson
1983, Open-File Report 83-736
Dry bulk density and grain density measurements were made on 182 samples of igneous, sedimentary, and metamorphic rocks from various world-wide localities. Total porosity values and both water-accessible and helium-accessible porosities were calculated from the density data. Magnetic susceptibility measurements were made on the solid samples and permeability and streaming...
Ground-water records for the area surrounding the Chickasaw National Recreation Area, Murray County, Oklahoma
Robert L. Goemaat, Cass C. Willard
1983, Open-File Report 83-27
This report is a compilation of ground-water records, water levels, and water-quality field determinations, for wells in a 132 square-mile (342 square kilometer) area surrounding the Chickasaw National Recreational Area in south-central Oklahoma. This information was collected in cooperation with the National Park Service. The location of the study area...
Stratigraphic framework and distribution of lignite on Crowleys Ridge, Arkansas
Charles R. Meissner
1983, Open-File Report 83-609
The purpose of this report is to establish a stratigraphic framework of lignite beds and associated strata of Crowleys Ridge, Arkansas. Drill hole data provided by the Arkansas Geological Commission is used in the synthesis and interpretation. Areas containing lignite of potential resource value are also delineated. To illustrate the...
Subsurface storage of freshwater in South Florida; a digital analysis of recoverability
Michael L. Merritt
1983, Open-File Report 83-536
As part of a feasibility study of cyclic freshwater injection, digital models were implemented to analyze the relation of recovery efficiency to various hydrogeologic conditions which could prevail in brackish aquifers and to various management regimes. The analyses implemented an approach in which the control for sensitivity testing was a...
Filling of Spirit Lake, Washington, May 18, 1980 to July 31, 1982
William Meyer, Philip J. Carpenter
1983, Open-File Report 82-771
The rockslide/debris avalanche from the north face of Mount St. Helens that precipitated the volcano 's eruption on May 18, 1980 , blocked outflow from Spirit Lake, Washington. There has been no surface outflow since that time. From May 21, 1980, when the first measurement of lake level was made,...
Specifications for updating USGS land use and land cover maps
Valerie A. Milazzo
1983, Open-File Report 83-116
To meet the increasing demands for up-to-date land use and land cover information, a primary goal of the U.S. Geological Survey's (USGS) national land use and land cover mapping program is to provide for periodic updating of maps and data in a timely and uniform manner. The technical specifications for...
Report of reprocessing of reflection seismic profile X-5 Waste Isolation Pilot Plant site, Eddy County, New Mexico
John J. Miller
1983, Open-File Report 83-316
Seismic reflection profile X-5 exhibits a 7,700 ft long anomalous zone of poor quality to nonexistent reflections between shotpoints 100 and 170, compared to the high-quality, flat-lying, coherent reflections on either side. Results from drill holes in the area suggest 'layer cake' geology with no detectable abnormalities such as faults...
Ground-water levels in Arkansas, spring 1983
Joe Edds
1983, Open-File Report 83-268
About 640 ground-water level measurements were made in observation wells in Arkansas in the spring of 1981. 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...
Landslide investigations, southern Cianjur Regency, West Java Province, Indonesia; a progress report
John R. Ege
1983, Open-File Report 83-597
Two landslide-monitoring sites have been established for a minimum 2-year investigation near the villages of Pasirpari and Cibacang in southern Cianjur Regency, West Java, Indonesia. Surveyed-in lines will measure amounts of surface movement and tilt, borings that produced exploratory cores now serve as slip-surface detectors and open-pipe piezometers, and rain...
Analyses of elutriates, native water, and bottom material in selected rivers and estuaries in western Oregon and Washington
Gregory J. Fuhrer, Frank A. Rinella
1983, Open-File Report 82-922
Chemical analyses of elutriates, bottom sediment and water samples for selected metals, nutrients and organic compounds including insecticides and herbicides have been made to provide data to determine short-term water quality conditions associated with dredging operations in rivers and estuaries. Between May and December 1980 data were collected as far...
