Anthony S. Navoy, Lois M. Voronin, Edward Modica
2005, Scientific Investigations Report 2004-5096
The Potomac-Raritan-Magothy aquifer system is hydraulically connected to the Delaware River in parts of Camden and Gloucester Counties, New Jersey, and has more limited contact with the river in Salem County, New Jersey. The aquifer system is used widely for water supply, and 122 production wells that are permitted by...

S.E. Cox, P.R. Bell, J.S. Lowther, P. C. Van Metre
2005, Scientific Investigations Report 2004-5090
Sediment cores were collected from six locations in Lake Roosevelt to determine the vertical distributions of trace-element concentrations in the accumulated sediments of Lake Roosevelt. Elevated concentrations of arsenic, cadmium, copper, lead, mercury, and zinc occurred throughout much of the accumulated sediments. Concentrations varied greatly within the sediment core profiles,...
Calibrating a tensor magnetic gradiometer using spin data
Robert E. Bracken, David V. Smith, Philip J. Brown
2005, Scientific Investigations Report 2005-5045
Scalar magnetic data are often acquired to discern characteristics of geologic source materials and buried objects. It is evident that a great deal can be done with scalar data, but there are significant advantages to direct measurement of the magnetic gradient tensor in applications with nearby sources, such as unexploded...
Reducing tensor magnetic gradiometer data for unexploded ordnance detection
Robert E. Bracken, Philip J. Brown
2005, Scientific Investigations Report 2005-5046
We performed a survey to demonstrate the effectiveness of a prototype tensor magnetic gradiometer system (TMGS) for detection of buried unexploded ordnance (UXO). In order to achieve a useful result, we designed a data-reduction procedure that resulted in a realistic magnetic gradient tensor and devised a simple way of viewing...

James G. Crock
2005, Open-File Report 2005-1030
The analytical chemist is faced with several challenges when determining mercury in biological and geological materials. These challenges include widespread mercury contamination, both in the laboratory and the environment, possible losses of mercury during sample preparation and digestion, the wide range of mercury values commonly observed, ranging from the low...

Changes in composition and porosity occurring during the thermal degradation of wood and wood components
David W. Rutherford, Robert L. Wershaw, Larry G. Cox
2005, Scientific Investigations Report 2004-5292
Samples of pine and poplar wood, pine bark, and purified cellulose and lignin were charred at temperatures ranging from 250?C to 500?C for times ranging from 1 hour to 168 hours. Changes in composition were examined by Fourier Transform Infrared (FTIR) and 13C Nuclear Magnetic Resonance (NMR) spectrometry, mass loss,...
Optically stimulated luminescence dating of late Holocene raised strandplain sequences adjacent to Lakes Michigan and Superior, Upper Peninsula, Michigan, USA
Erin P. Argyilan, Steven L. Forman, John W. Johnston, Douglas A. Wilcox
2005, Quaternary Research (63) 122-135
This study evaluates the accuracy of optically stimulated luminescence to date well-preserved strandline sequences at Manistique/Thompson bay (Lake Michigan), and Tahquamenon and Grand Traverse Bays (Lake Superior) that span the past ∼4500 yr. The single aliquot regeneration (SAR) method is applied to produce absolute ages for littoral and eolian sediments....

Ground water provides approximately 40 percent of the nation’s public water supply, and the total percentage of withdrawals for irrigation has increased from 23 percent in 1950 to 42 percent in 2000. Ground water also is a major contributor to flow in many streams and rivers in the United States...

Todd J. Greene, Alan R. Carroll, Marwan A. Wartes, Stephan A. Graham, Joseph L. Wooden
2005, Journal of Sedimentary Research (75) 251-267
We employ petrographic and advanced geochemical techniques to better document the evolution of the Turpan–Hami basin based on the unique geologic histories of the arc terranes that served as potential sources of Turpan–Hami deposits. First, a provenance study of Permian through Cretaceous sandstone of the Turpan–Hami basin reveals temporal and...

R. Hershey, J. Thomas, T. Rose, James B. Paces, I. M. Farnham, F. C. Benedict
2005, Technical Report DOE/NV/13609-36
The principal pathway for radionuclide migration from underground tests in Frenchman Flat, on the Nevada Test Site, to the accessible environment is groundwater flow. Two potential pathways for radionuclide transport via groundwater have been identified from hydrologic data: (1) radionuclide transport downward from the alluvial and volcanic...
From climate-change spaghetti to climate-change distributions for 21st Century California
M. D. Dettinger
2005, San Francisco Estuary and Watershed Science (3) 1-14
The uncertainties associated with climate-change projections for California are unlikely to disappear any time soon, and yet important long-term decisions will be needed to accommodate those potential changes. Projection uncertainties have typically been addressed by analysis of a few scenarios, chosen based on availability or to capture the extreme cases...
Balancing the generation and elimination of reactive oxygen species
Rusty Rodriguez, Regina Redman
2005, PNAS (102) 3175-3176
Fossil records suggest that bacteria developed the ability to photosynthesize ≈3,500 million years ago (mya), initiating a very slow accumulation of atmospheric oxygen (1). Recent geochemical models suggest that atmospheric oxygen did not accumulate to levels conducive for aerobic life until 500–1,000 mya (2, 3). The oxygenation of...

Computation of discharge using the index-velocity method in tidally affected areas
Catherine A. Ruhl, Michael R. Simpson
2005, Scientific Investigations Report 2005-5004
Computation of a discharge time-series in a tidally affected area is a two-step process. First, the cross-sectional area is computed on the basis of measured water levels and the mean cross-sectional velocity is computed on the basis of the measured index velocity. Then discharge is calculated as the product of...
Geochemistry and the understanding of ground-water systems
Pierre D. Glynn, Niel Plummer
2005, Hydrogeology Journal (13) 263-287
Geochemistry has contributed significantly to the understanding of ground-water systems over the last 50 years. Historic advances include development of the hydrochemical facies concept, application of equilibrium theory, investigation of redox processes, and radiocarbon dating. Other hydrochemical concepts, tools, and techniques have helped elucidate mechanisms of flow and transport in...
The future of hydrogeology
Clifford I. Voss
2005, Hydrogeology Journal (13) 1-6
“The Future of Hydrogeology” would seem to be an overly ambitious topic for a theme issue of Hydrogeology Journal or for any other journal. Only a modicum of common sense and experience provides the insight that predicting the future of a science is a task fraught with uncertainty...
