Hydrologic data for the Great and Denbow heaths in eastern Maine, October 1981 through October 1982
Wallace J. Nichols
1983, Open-File Report 83-865
Hydrologic data collected on the Great and Denbow Heaths, Maine, include precipitation, pan evaporation, air temperatures, streamflow, and ground water levels. These data were collected for a peat bog hydrology study conducted in cooperation with the Maine Geological Survey. The data network consisted of climate information from three rain gages,...
Hydrologic data for the Great and Denbow heaths in eastern Maine, October 1980 through September 1981
Wallace J. Nichols, J.A. Smath, J.T. Adamik
1983, Open-File Report 83-866
Hydrologic data collected on the Great and Denbow Heaths, Maine, include precipitation, pan evaporation, air temperatures, streamflow, groundwater levels, and water quality constituents. These data were collected for a peat bog hydrology study conducted in cooperation with the Maine Geological Survey. The data network consisted of climate information from three...
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...
A new event detector designed for the Seismic Research Observatories
James N. Murdock, Charles R. Hutt
1983, Open-File Report 83-785
A new short-period event detector has been implemented on the Seismic Research Observatories. For each signal detected, a printed output gives estimates of the time of onset of the signal, direction of the first break, quality of onset, period and maximum amplitude of the signal, and an estimate of the...
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...
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...
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,...
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...
Drainage areas of selected sites on streams in North Carolina
Robert L. Meikle
1983, Open-File Report 83-211
For the past several years, drainage-area data have been determined for approximately 12,400 selected sites on streams in North Carolina. Location information, including distance of nearby towns or other landmarks, latitude and longitude coordinates, county in which the site lies, and the name of the latest topographic maps on which...
A hydrogeochemical survey in east-central Nevada
John B. McHugh, W. Roger Miller, Walter H. Ficklin
1983, Open-File Report 83-286
A hydrogeochemical survey utilizing waters from springs and wells was conducted in east-central Nevada. None of the trace elements commonly associated with mineralization were found to be highly anomalous in the study area. Slightly anomalous values for some elements were found in the southern valleys of the study area and...
$ANBA; a rapid, combined data acquisition and correction program for the SEMQ electron microprobe
James J. McGee
1983, Open-File Report 83-817
$ANBA is a program developed for rapid data acquisition and correction on an automated SEMQ electron microprobe. The program provides increased analytical speed and reduced disk read/write operations compared with the manufacturer's software, resulting in a doubling of analytical throughput. In addition, the program provides enhanced analytical features such as...
Stratigraphy, structure, and palinspastic synthesis of the western Brooks Range, northwestern Alaska
Charles F. Mayfield, Irvin L. Tailleur, Inyo Ellersieck
1983, Open-File Report 83-779
This report is an effort to describe and decipher the mid-Paleozoic to Lower Cretaceous stratigraphy and the orogenic evolution of the western Brooks Range. The western Brooks Range primarily is composed of stacks of complexly deformed thrust sheets that contain mostly coeval sequences of rocks with slightly different lithologic facies....
Long-range plans for hydrologic investigations in New Mexico
H. L. Case III, G. E. Welder
1983, Open-File Report 83-696
Objectives of the hydrologic-data-collection projects presented in this report include continuing to identify future data needs; conducting an analysis of the water-quality, ground-water, and surface-water observation networks; and entering all available current and historical hydrologic data into the U.S. Geological Survey Water Data Storage and Retrieval System (WATSTORE). Objectives of...
Comparison of the chemical characteristics of the uranium deposits of the Morrison Formation in the Grants uranium region, New Mexico
C.S. Spirakis, C. T. Pierson
1983, Open-File Report 83-380
Statistical treatment of the chemical data of samples from the northeast Church Rock area, Ruby deposit, Mariano Lake deposit, and the Ambrosia Lake district indicates that primary ore-forming processes concentrated copper, iron, magnesium, manganese, molybdenum, selenium, vanadium, yttrium, arsenic, organic carbon, and sulfur, along with uranium. A barium halo that...
