Age and quality of ground water and sources of nitrogen in the surficial aquifers in Pumpkin Creek Valley, western Nebraska, 2000
G. V. Steele, J. C. Cannia, S. S. Sibray, V. L. McGuire
2005, Scientific Investigations Report 2005-5157
Ground water is the source of drinking water for the residents of Pumpkin Creek Valley, western Nebraska. In this largely agricultural area, shallow aquifers potentially are susceptible to nitrate contamination. During the last 10 years, ground-water levels in the North Platte Natural Resources District have declined and contamination has become...
Geologic map of the northern plains of Mars
Kenneth L. Tanaka, James A. Skinner, Trent M. Hare
2005, Scientific Investigations Map 2888
The northern plains of Mars cover nearly a third of the planet and constitute the planet's broadest region of lowlands. Apparently formed early in Mars' history, the northern lowlands served as a repository both for sediments shed from the adjacent ancient highlands and for volcanic flows and deposits from...
Regionalized equations for bankfull-discharge and channel characteristics of streams in New York State—Hydrologic Region 6 in the Southern Tier of New York
Christiane I. Mulvihill, Anne G. Ernst, Barry P. Baldigo
2005, Scientific Investigations Report 2005-5100
Equations that relate bankfull discharge and channel characteristics (width, depth, and cross-sectional area) to drainage-area size at gaged sites are needed to define bankfull discharge and channel dimensions at ungaged sites and to provide information for watershed assessments, stream-channel classification, and the design of stream-restoration projects. Such equations are most...
Instream flow characterization of upper Salmon River basin streams, central Idaho, 2004
Terry R. Maret, Jon Hortness, Douglas S. Ott
2005, Scientific Investigations Report 2005-5212
Anadromous fish populations in the Columbia River Basin have plummeted in the last 100 years. This severe decline led to Federal listing of Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss) stocks as endangered or threatened under the Endangered Species Act (ESA) in the 1990s. Historically, the upper Salmon...

The gravity method was the first geophysical technique to be used in oil and gas exploration. Despite being eclipsed by seismology, it has continued to be an important and sometimes crucial constraint in a number of exploration areas. In oil exploration the gravity method is particularly applicable in salt provinces,...

A computer program for predicting recharge with a master recession curve
Christopher S. Heppner, John R. Nimmo
2005, Scientific Investigations Report 2005-5172
Water-table fluctuations occur in unconfined aquifers owing to ground-water recharge following precipitation and infiltration, and ground-water discharge to streams between storm events. Ground-water recharge can be estimated from well hydrograph data using the water-table fluctuation (WTF) principle, which states that recharge is equal to the product of the water-table rise...

2005, Data Series 143
The U.S. Geological Survey (USGS), in collaboration with the Louisiana Department of Environmental Quality, monitored bacteriological quality of water at 22 sites in and around Lake Pontchartrain, La., for three consecutive weeks beginning September 13, 2005, following hurricanes Katrina and Rita and the associated flooding. Samples were collected and analyzed...
Coordinating NEHRP Post-Earthquake Investigations: Exercising the Plan
Thomas L. Holzer, Charles Scawthorn, Christopher Rojahn
2005, Earthquake Spectra (21) 1043-1062
Three exercises of The Plan to Coordinate NEHRP Post-Earthquake Investigations were developed and implemented in late 2003 and early 2004 in order to test the Plan itself via realistic scenarios, and for the NEHRP agencies to learn how to coordinate post-earthquake investigations. The exercises were selected to cover a range...

2005, Conference Paper, Water Environment Federation’s WEFTEC 78th Annual Technical Exhibition and Conference, conference proceedings
Across the United States, there is a rapidly growing awareness of the occurrence and the toxicological impacts of natural and synthetic trace compounds in the environment. These trace compounds, referred to as emerging contaminants (ECs), are reported to cause a range of negative impacts in the environment, such as adverse...
Non-lethal estimation of body composition of Yukon River salmon
F. Joseph Margraf, Kyle J. Hartman, M. Keith Cox
2005, Report
Because of the importance of Chinook salmon to commercial and subsistence fisheries on the Yukon River, further study of the factors that may affect the success of this species and our ability to manage the fisheries is warranted. Critical to these studies is the determination of the amount of lipids...

Eugene A. Fosnight, H. Strand, Benjamin White
2005, Conference Paper
The Convention on Biological Diversity’s (CBD) VIth Conference of the Parties (COP) and the World Summit on Sustainable Development agreed to a target to achieve a significant reduction of the rate of biodiversity loss by 2010. The VIIth COP adopted a conceptual framework to facilitate the assessment of global progress...

Results of a 2-year field study of the regolith-fractured bedrock ground-water system at the Lake Wheeler Road research station in Wake County, North Carolina, indicate both disconnection and interaction among components of the ground-water system. The three components of the ground-water system include (1) shallow, porous regolith; (2) a transition...

2005, Scientific Investigations Report 2005-5208
The Ozark aquifer in northern Arkansas comprises dolomites, limestones, sandstones, and shales of Late Cambrian to Middle Devonian age, and ranges in thickness from approximately 1,100 feet to more than 4,000 feet. Hydrologically, the aquifer is complex, characterized by discrete and discontinuous flow components with large variations in permeability. The...
Ground-water availability from surficial aquifers in the Red River of the North Basin, Minnesota
Thomas H.C. Reppe
2005, Scientific Investigations Report 2005-5204
Population growth and commercial and industrial development in the Red River of the North Basin in Minnesota, North Dakota, and South Dakota have prompted the Bureau of Reclamation, U.S. Department of the Interior, to evaluate sources of water to sustain this growth. Nine surficial-glacial (surficial) aquifers (Buffalo, Middle River, Two...
Development of regional curves relating bankfull-channel geometry and discharge to drainage area for streams in Pennsylvania and selected areas of Maryland
Jeffrey J. Chaplin
2005, Scientific Investigations Report 2005-5147
Natural-stream designs are commonly based on the dimensions of the bankfull channel, which is capable of conveying discharges that transport sediment without excessive erosion or deposition. Regional curves relate bankfull-channel geometry and discharge to drainage area in watersheds with similar runoff characteristics and commonly are utilized by practitioners of natural-stream...
Water, ice, and meteorological measurements at South Cascade glacier, Washington, balance year 2003

2005, Scientific Investigations Report 2005-5210
Winter snow accumulation and summer snow and ice ablation were measured at South Cascade Glacier, Washington, to estimate glacier mass-balance quantities for balance year 2003. The 2003 glacier-average maximum winter snow balance was 2.66 meters water equivalent, which was about equal to the average of such balances for the glacier...

Obtaining high-quality measurements close to a large earthquake is not easy: one has to be in the right place at the right time with the right instruments. Such a convergence happened, for the first time, when the 28 September 2004 Parkfield, California, earthquake occurred on the San Andreas fault in...
