ties. Although the NROK median total recoverable lead concentration was the smallest among the three Western study areas compared, concentrations in several NROK samples were an order of magnitude larger than the maximum concentrations measured in the Upper Colorado River and Great Salt Lake Basins. Dissolved cadmium, dissolved lead, and total recoverable zinc concentrations at NROK sites were...

Fecal-indicator bacteria in the Yakima River Basin, Washington: An examination of 1999 and 2000 synoptic-sampling data and their relation to historical data
Jennifer L. Morace, Stuart W. McKenzie
2002, Water-Resources Investigations Report 2002-4054
The Yakima Basin National Water-Quality Assessment Program collected fecal-coliform bacteria samples during three synoptic samplings to identify and quantify the cause, source, transport, and effects of fecal-indicator bacteria in Yakima River Basin streams. The August 1999 synoptic sampling targeted the Yakima River main-stem and tributary sites, while the July and...
Characterization of hydraulic conductivity of the alluvium and basin fill, Pinal Creek Basin near Globe, Arizona
Cory E. Angeroth
2002, Water-Resources Investigations Report 2002-4205
Acidic waters containing elevated concentrations of dissolved metals have contaminated the regional aquifer in the Pinal Creek Basin, which is in Gila County, Arizona, about 100 kilometers east of Phoenix. The aquifer is made up of two geologic units: unconsolidated stream alluvium and consolidated basin fill. To better understand how...
Water quality of the Mississippian carbonate aquifer in parts of middle Tennessee and northern Alabama, 1999
James A. Kingsbury, John M. Shelton
2002, Water-Resources Investigations Report 2002-4083
Water-quality data for nitrate, fecal-indicator bacteria, pesticides, and volatile organic compounds collected in parts of Middle Tennessee and northern Alabama indicate that the Mississippian carbonate aquifer in these areas is susceptible to contamination from point and nonpoint sources. Thirty randomly located wells (predominantly domestic), two springs, and two additional public-supply...

2002, Human Ecology Review (9) 67-71
The role of science in society is evolving as we enter the 21st century. The report, Science — The Endless Frontier (Bush 1990[1945]), outlined a model of national scientific research that served the country for 50 years. The contract between science and society established in that report stipulated that science...
Integrating satellite and climate data for U.S. drought mapping and monitoring: First steps
Jesslyn F. Brown, Tsegaye Tadesse, Bradley C. Reed
2002, Conference Paper, Conference on Biometeorology and Aerobiology, 15th, Joint with the International Congress on Biometeorology, 16th, Kansas City, Mo., 12 October–1 November 2002, Proceedings
Although droughts are normal, recurring climate phenomena, they challenge our current ability to plan, predict, monitor, and provide relief to drought stricken areas. Because of the spatial and temporal variability of droughts, we need to improve the tools available to map and monitor them on many scales from local to...
A prototype drought monitoring system integrating climate and satellite data

2002, Conference Paper, Integrated remote sensing at the global, regional, and local scale
Droughts are natural hazards with varying patterns in space, time, and intensity. Their dynamic character challenges our ability in planning, predicting, monitoring, and providing relief to affected areas. Because of the spatial and temporal variability and multiple impacts of droughts, we need to improve the tools and data available for...
Is it More Important to Characterize Heterogeneity or Differences in Hydraulic Conductivity Measurements?
G. Barth, Mary C. Hill, Tissa H. Illangasekare, Harihar Rajaram
2002, Conference Paper, ”Bridging the gap between measurements and modelling”, Special issue with selected papers from the IAHR International Groundwater
As a first step toward understanding the role of sedimentary structures in flow and transport through porous media, this work deterministically examines how transport simulations compare to observed transport through simple, artificial structures in a laboratory experiment. Small-scale laboratory-measured values of hydraulic conductivity were used to simulate transport in an...

Magnetobiochronologic synthesis of ODP Leg 178 rise sediments from the Pacific sector of the Southern Ocean: Sites 1095, 1096, and 11011
Masao Iwai, Gary D. Acton, David Lazarus, Lisa E. Osterman, Trevor Williams
2002, Proceedings of the Ocean Drilling Program: Scientific Results 178-36
During Ocean Drilling Program (ODP) Leg 178, eight holes were drilled at three sites (1095, 1096, and 1101) on the continental rise along the western Antarctic Peninsula. The rise sediments proved to be good paleomagnetic recorders and provided continuous magnetostratigraphic records at all three sites. Biosiliceous microfossils, particularly diatoms and...
Time‐lapse inversion of crosswell radar data
Frederick D. Day-Lewis, Jerry M. Harris, Steven M. Gorelick
2002, Geophysics (67) 1740-1752
The combination of differential radar tomography with conventional tracer and/or hydraulic tests facilitates high‐resolution characterization of subsurface heterogeneity and enables the identification of preferential flow paths. In dynamic imaging, each tomogram is typically inverted independently, under the assumption that data sets are collected quickly relative to changes in the imaged...

A new method for GPS-based wind speed determinations during airborne volcanic plume measurements
Michael P. Doukas
2002, Open-File Report 2002-395
Begun nearly thirty years ago, the measurement of gases in volcanic plumes is today an accepted technique in volcano research. Volcanic plume measurements, whether baseline gas emissions from quiescent volcanoes or more substantial emissions from volcanoes undergoing unrest, provide important information on the amount of gaseous output of a volcano...
