Thermal maturity patterns (CAI and %Ro) in the Ordovician and Devonian rocks of the Appalachian basin in West Virginia
John E. Repetski, Robert T. Ryder, Katharine Lee Avary, Michael H. Trippi
2005, Open-File Report 2005-1078
The objective of this study is to enhance existing thermal maturity maps in West Virginia by establishing: 1) new subsurface CAI data points for the Ordovician and Devonian and 2) new %Ro and Rock Eval subsurface data points for Middle and Upper Devonian black shale units. Thermal maturity values for...
Height changes along selected lines through the Death Valley region, California and Nevada, 1905-1984
Robert O. Castle, Thomas D. Gilmore, James P. Walker, Susan A. Castle
2005, Open-File Report 2005-1133
Comparisons among repeated levelings along selected lines through the Death Valley region of California and adjacent parts of Nevada have disclosed surprisingly large vertical displacements. The vertical control data in this lightly populated area is sparse; moreover, as much as a third of the recovered data is so thoroughly contaminated...
A guide to the proper selection and use of federally approved sediment and water-quality samplers
Broderick E. Davis, Federal Interagency Sedimentation Project
2005, Open-File Report 2005-1087
The Federal Interagency Sedimentation Project (FISP) was created in 1939 to unify and standardize the research and development activities of Federal agencies involved in fluvial sediment studies1,2. Research and development conducted by the FISP originally focused on hydraulic and mechanical aspects of sediment sampling. The mission of the FISP has...
Influence of Riparian Tree Phenology on Lower Colorado River Spring-Migrating Birds: Implications of Flower Cueing
Laura J. McGrath, Charles van Riper III
2005, Open-File Report 2005-1140
Executive Summary Neotropical migrant birds make choices about which habitats are most likely to provide successful foraging locations during migration, but little is known about how these birds recognize and process environmental clues that indicate the presence of prey species. Aspects of tree phenology, notably flowering of trees along the lower...
Managing Fire in the Northern Chihuahuan Desert: A Review and Analysis of the Literature
Brooke S. Gebow, William L. Halvorson
2005, Open-File Report 2005-1157
Executive Summary This report began as a literature review (Gebow and Halvorson 2001) conducted for fire planners at Carlsbad Caverns National Park who were seeking information about (1) the natural state of park vegetation, (2) northern Chihuahuan Desert natural fire regimes, and (3) fire effects on park plant species. It is...
Literature Review and Annotated Bibliography: Water Requirements of Desert Ungulates
James W. Cain III, Paul R. Krausman, Steven S. Rosenstock, Jack C. Turner
2005, Open-File Report 2005-1141
Executive Summary Ungulates adapted to desert areas are able to survive extreme temperatures and limited water availability. This ability is largely due to behavioral, morphological, and physiological adaptations that allow these animals to avoid or tolerate extreme environmental conditions. The physiological adaptations possessed by ungulates for thermoregulation and maintenance of water...
Surficial deposits in the Bear Lake Basin
Marith C. Reheis, Benjamin J.C. Laabs, Richard M. Forester, John P. McGeehin, Darrell S. Kaufman, Jordon Bright
2005, Open-File Report 2005-1088
Mapping and dating of surficial deposits in the Bear Lake drainage basin were undertaken to provide a geologic context for interpretation of cores taken from deposits beneath Bear Lake, which sometimes receives water and sediment from the glaciated Bear River and sometimes only from the small drainage basin of Bear...
Geochemistry of sediments in cores and sediment traps from Bear Lake, Utah and Idaho
James L. Bischoff, Kathleen Cummins, Donald D. Shamp
2005, Open-File Report 2005-1215
The present study of Bear Lake began in 1998. Initially, the study utilized sediments from three long cores (up to 5 m) previously collected in 1996 and short cores (up to 40 cm) collected in 1998. The short cores were specifically acquired to preserve the uppermost layers of sediment that...
Digital data and derivative products from a high-resolution aeromagnetic survey of the central San Luis basin, covering parts of Alamosa, Conejos, Costilla, and Rio Grande counties, Colorado, and Taos county, New Mexico
Viki Bankey, V. J. S. Grauch, Ank Webbers, Inc PRJ
2005, Open-File Report 2005-1200
This report describes data collected from a high-resolution aeromagnetic survey flown over the central San Luis basin during October, 2004, by PRJ, Inc., on contract to the U.S. Geological Survey (USGS). The survey extends from just north of Alamosa, Colorado, southward to just northwest of Taos, New Mexico. It covers...
Evaluation of unsaturated-zone solute-transport models for studies of agricultural chemicals
Bernard T. Nolan, E. Randall Bayless, Christopher T. Green, Sheena Garg, Frank D. Voss, David C. Lampe, Jack E. Barbash, Paul D. Capel, Barbara A. Bekins
2005, Open-File Report 2005-1196
Seven unsaturated-zone solute-transport models were tested with two data sets to select models for use by the Agricultural Chemical Team of the U.S. Geological Survey's National Water-Quality Assessment Program. The data sets were from a bromide tracer test near Merced, California, and an atrazine study in the White River Basin,...
Estimation of agricultural pesticide use in drainage basins using land cover maps and county pesticide data
Naomi Nakagaki, David M. Wolock
2005, Open-File Report 2005-1188
A geographic information system (GIS) was used to estimate agricultural pesticide use in the drainage basins of streams that are studied as part of the U.S. Geological Survey?s National Water-Quality Assessment (NAWQA) Program. Drainage basin pesticide use estimates were computed by intersecting digital maps of drainage basin boundaries with an...
Quality-assurance plan for the analysis of fluvial sediment by the U.S. Geological Survey Kentucky Water Science Center Sediment Laboratory
Elizabeth A. Shreve, Aimee C. Downs
2005, Open-File Report 2005-1230
This report describes laboratory procedures used by the U.S. Geological Survey Kentucky Water Science Center Sediment Laboratory for the processing and analysis of fluvial-sediment samples for concentration of sand and finer material. The report details the processing of a sediment sample through the laboratory from receiving the sediment sample, through...
