Structure of the Tucson Basin, Arizona from gravity and aeromagnetic data
Victoria Louise Rystrom
2003, Open-File Report 2003-116
Interpretation of gravity and high-resolution aeromagnetic data reveal the three-dimensional geometry of the Tuscson Basin, Arizona and the lithology of its basement. Limited drill hole and seismic data indicate that the maximum depth to the crystalline basement is approximately 3600 meters and that the sedimentary sequences in the upper ~2000...
Geology of Badlands National Park: A preliminary report
Philip W. Stoffer
2003, Open-File Report 2003-35
Badlands National Park is host to perhaps the most scenic geology and landscape features in the Western Interior region of the United States. Ongoing erosion that forms the "badlands" exposes ancient sedimentary strata of Late Cretaceous through Oligocene age. Quaternary erosional and depositional processes are responsible for most of the...

The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geology-based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States, focusing on the distribution, quantity, and availability of oil and natural gas resources. The USGS...

Trends in concentrations of polychlorinated biphenyls in fish tissue from selected sites in the Delaware River basin in New Jersey, New York, and Pennsylvania, 1969-98
Karen Riva-Murray, Robin A. Brightbill, Michael D. Bilger
2003, Water-Resources Investigations Report 2001-4066
 Polychlorinated biphenyl (PCB) concentrations in fish tissue collected during the 1990's from selected sites in the Delaware River Basin were compared with concentrations in fish tissue collected during 1969-88. Data collected by State and Federal agencies on concentrations in whole-body common carp (Cyprinus carpio) and white sucker (Catostomus commersoni), and...
Simulation of Ground-Water Flow in the Irwin Basin Aquifer System, Fort Irwin National Training Center, California
Jill N. Densmore
2003, Water-Resources Investigations Report 2002-4264
Ground-water pumping in the Irwin Basin at Fort Irwin National Training Center, California resulted in water-level declines of about 30 feet from 1941 to 1996. Since 1992, artificial recharge from wastewater-effluent infiltration and irrigation-return flow has stabilized water levels, but there is concern that future water demands associated with expansion...
Escherichia coli at Ohio bathing beaches—Distribution, sources, wastewater indicators, and predictive modeling
Donna S. Francy, Amie M. Gifford, Robert A. Darner
2003, Water-Resources Investigations Report 2002-4285
Results of studies during the recreational seasons of 2000 and 2001 strengthen the science that supports monitoring of our Nation's beaches. Water and sediment samples were collected and analyzed for concentrations of Escherichia coli (E. coli).  Ancillary water-quality and environmental data were collected or compiled to determine their relation to...
A geographic information system tool to solve regression equations and estimate flow-frequency characteristics of Vermont Streams
Scott A. Olson, Gary D. Tasker, Craig M. Johnston
2003, Open-File Report 2002-494
Estimates of the magnitude and frequency of streamflow are needed to safely and economically design bridges, culverts, and other structures in or near streams. These estimates also are used for managing floodplains, identifying flood-hazard areas, and establishing flood-insurance rates, but may be required at ungaged sites where no observed flood...
Development of regional curves of bankfull-channel geometry and discharge for streams in the non-urban, Piedmont Physiographic Province, Pennsylvania and Maryland
Peter J. Cinotto
2003, Water-Resources Investigations Report 2003-4014
Stream-restoration projects utilizing natural stream designs frequently are based on the bankfull-channel characteristics of stream reaches that can accommodate streamflow and sediment transport without excessive erosion or deposition and lie within a watershed that has similar runoff characteristics. The bankfull channel at an ungaged impaired site or reference reach is...
Delineation of water sources for public-supply wells in three fractured-bedrock aquifer systems in Massachusetts
Forest P. Lyford, Carl S. Carlson, Bruce P. Hansen
2003, Water-Resources Investigations Report 2002-4290
Fractured-bedrock aquifer systems in West Newbury, Maynard, and Paxton, Massachusetts, were studied to advance methods of data collection and analysis for delineating contributing areas to public-supply wells completed in fractured rock and for determining the effects of pumping on streams and wetlands. Contributing areas, as defined for this study, include...
Simulated ground-water flow in the Hueco Bolson, an alluvial-basin aquifer system near El Paso, Texas
Charles E. Heywood, Richard M. Yager
2003, Water-Resources Investigations Report 2002-4108
The neighboring cities of El Paso, Texas, and Ciudad Juarez, Chihuahua, Mexico, have historically relied on ground-water withdrawals from the Hueco Bolson, an alluvial-aquifer system, to supply water to their growing populations. By 1996, ground-water drawdown exceeded 60 meters in some areas under Ciudad Juarez and El Paso. A simulation...
Evidence of disease-related amphibian decline in Colorado
Erin Muths, Paul Stephen Corn, Allan P. Pessier, D. Earl Green
2003, Biological Conservation (110) 357-365
The recent discovery of a pathogenic fungus (Batrachochytrium dendrobatidis) associated with declines of frogs in the American and Australian tropics, suggests that at least the proximate cause, may be known for many previously unexplained amphibian declines. We have monitored boreal toads in Colorado since 1991 at four sites using capturea??recapture...

2003, Conference Paper, Proceedings: ISPRS Working Group IV/9 Workshop
Positional control for MDIM 2.1 comes from a new geodetic/photogrammetric solution of the global Mars Mariner 9 and Viking image control network. The details of this network solution are described here. This network incorporates 1,054 Mariner 9 and 5,317 Viking Orbiter images. Accuracy of the new solution is improved primarily...
Hydrothermal alteration at the Lonar Lake impact structure, India: Implications for impact cratering on Mars
Justin Hagerty, Horton E. Newsom
2003, Meteoritics and Planetary Science (38) 365-381
The 50,000 year old, 1.8 km diameter Lonar crater is one of only two known terrestrial craters to be emplaced in basaltic target rock (the 65 million year old Deccan Traps). The composition of the Lonar basalts is similar to martian basaltic meteorites, which establishes Lonar as an excellent analogue...
