Two-dimensional direct-current resistivity survey to supplement borehole data in ground-water models of the former Blaine Naval Ammunition Depot, Hastings, Nebraska, September 2003
Wade H. Kress, Lyndsay B. Ball, Andrew Teeple, Michael J. Turco
2006, Data Series 172
The former Blaine Naval Ammunition Depot located immediately southeast of Hastings, Nebraska, was an ammunition facility during World War II and the Korean Conflict. Waste-management practices during operation and decommissioning of the former Depot resulted in soil and ground-water contamination. Ground-water models have been used by the U.S. Army Corps...
Tsunami hazards— A national threat
Water Resources Division, U.S. Geological Survey
2006, Fact Sheet 2006-3023
In December 2004, when a tsunami killed more than 200,000 people in 11 countries around the Indian Ocean, the United States was reminded of its own tsunami risks. In fact, devastating tsunamis have struck North America before and are sure to strike again. Especially vulnerable are the five Pacific States--Hawaii, Alaska,...
Volcano hazards: A national threat
Water Resources Division, U.S. Geological Survey
2006, Fact Sheet 2006-3014
When the violent energy of a volcano is unleashed, the results are often catastrophic. The risks to life, property, and infrastructure from volcanoes are escalating as more and more people live, work, play, and travel in volcanic regions. Since 1980, 45 eruptions and 15 cases of notable volcanic unrest have...
Earthquake hazards: A national threat
Water Resources Division, U.S. Geological Survey
2006, Fact Sheet 2006-3016
Earthquakes are one of the most costly natural hazards faced by the Nation, posing a significant risk to 75 million Americans in 39 States. The risks that earthquakes pose to society, including death, injury, and economic loss, can be greatly reduced by (1) better planning, construction, and mitigation practices before...

Flood hazards— A national threat
Water Resources Division, U.S. Geological Survey
2006, Fact Sheet 2006-3026
In the late summer of 2005, the remarkable flooding brought by Hurricane Katrina, which caused more than \$ 200 billion in losses, constituted the costliest natural disaster in U.S. history. However, even in typical years, flooding causes billions of dollars in damage and threatens lives and property in every State....
Chemical and isotopic database of water and gas from hydrothermal systems with an emphasis for the western United States

2006, Data Series 169
Chemical and isotope data accumulated by two USGS Projects (led by I. Barnes and R. Mariner) over a time period of about 40 years can now be found using a basic web search or through an image search (left). The data are primarily chemical and isotopic...
Development and application of a regression equation for estimating the occurrence of atrazine in shallow ground water beneath agricultural areas of the United States
Paul E. Stackelberg, Robert J. Gilliom, David M. Wolock, Kerie J. Hitt
2006, Scientific Investigations Report 2005-5287
Results from 52 ground-water studies throughout the United States were used to examine relations between the occurrence of atrazine in shallow ground water in agricultural settings and explanatory variables that describe the natural setting, agricultural-management practices, and the type and amount of development in each area. The explanatory variables that...

2006, Scientific Investigations Report 2006-5005
Water-quality samples were collected from sites in four irrigation return-flow drainage basins in the Columbia Basin Project from July 2002 through October 2004. Ten samples were collected throughout the irrigation season (generally April through October) and two samples were collected during the non-irrigation season. Samples were analyzed for temperature, pH,...

Emergence of ratio-dependent and predator-dependent functional responses for pollination mutualism and seed parasitism
Donald L. DeAngelis, J. Nathaniel Holland
2006, Ecological Modelling (191) 551-556
Prey (N) dependence [g(N)], predator (P) dependence [g(P) or g(N,P)], and ratio dependence [f(P/N)] are often seen as contrasting forms of the predator's functional response describing predator consumption rates on prey resources in predator–prey and parasitoid–host interactions. Analogously, prey-, predator-, and ratio-dependent functional responses are apparently alternative functional responses for other...
The changing shapes of active volcanoes: History, evolution, and future challenges for volcano geodesy
Michael P. Poland, Michael W. Hamburger, Andrew V. Newman
2006, Journal of Volcanology and Geothermal Research (150) 1-13
At the very heart of volcanology lies the search for the 'plumbing systems' that form the inner workings of Earth’s active volcanoes. By their very nature, however, the magmatic reservoirs and conduits that underlie these active volcanic systems are elusive; mostly they are observable only through circumstantial evidence, using indirect,...
