The USGS National Research Program for water resources supports hydrologic research in support of the mission of the U.S. Geological Survey. Site provides links to search for current projects and for postdoctoral opportunities.
Retrieval system to locate websites on publications and compilations on biological resources. Searches can be made by type, such as checklists, distribution, and regional overviews, by taxon, and by geography, including global, U.S., and Canada.
Using a performance-based geological assessment methodology, we estimated mean volumes of 1,345 billion cubic feet of potentially technically recoverable gas and 168 million barrels of technically recoverable oil and natural gas liquids here.
Estimates of known and undiscovered copper resources total nearly 60 million metric tons of copper. Iron resources in known deposits total 2200 million metric tons of ore. Twenty mineralized areas meriting further study were identified.
Planned analysis of the sensitivity of groundwater levels to changes in air temperature and precipitation. Changes in groundwater recharge and discharge also will be correlated with other hydrologic indicators.
