This data set represents the 30-year (1971-2000) average annual maximum temperature in Celsius multiplied by 100 compiled for every catchment of NHDPlus for the conterminous United States. The source data were the United States Average Monthly or Annual Minimum Temperature, 1971 - 2000 raster dataset produced by the PRISM Group...
Use of electrical imaging and distributed temperature sensing methods to characterize surface water–groundwater exchange regulating uranium transport at the Hanford 300 Area, Washington
Lee D. Slater, Dimitrios Ntarlagiannis, Frederick D. Day-Lewis, Kisa Mwakanyamale, Roelof J. Versteeg, Andy Ward, Christopher Strickland, Carole D. Johnson, John W. Lane Jr.
2010, Water Resources Research (46)
We explored the use of continuous waterborne electrical imaging (CWEI), in conjunction with fiber‐optic distributed temperature sensor (FO‐DTS) monitoring, to improve the conceptual model for uranium transport within the Columbia River corridor at the Hanford 300 Area, Washington. We first inverted resistivity and induced polarization CWEI data sets for distributions...

Applications of stable isotopes for regional to national-scale water quality and environmental monitoring programs
Carol Kendall, Megan B. Young, Steven R. Silva
J. West, T. Dawson, K. Tu, editor(s)
2010, Book chapter, Isoscapes
Isotopes are a potentially powerful component of monitoring and assessment programs aimed at quantifying and mitigating alterations to environments from human activities. In particular, isotopic techniques have proved useful for tracing sources and sinks of various pollutants in large river basins, wetlands, and airsheds. Many of these studies have been...
