Net Ecosystem Production (NEP) of the Great Plains, United States [ More info] Geographic analysis of the changes in storage and release of carbon in this large area as land use patterns, especially agriculture, have changed.
USGS National Map of Surficial Mineralogy [ More info] Maps of exposed surface mineral groups derived from automated spectral analysis of satellite and airborne imaging systems; these data suggest areas that may contain mineral deposits of various types.
The 3D Elevation Program: summary for Texas [ More info] Summarizes the expected value over the next decade of the 3D Elevation Program for this state
Geochemical and mineral maps from soils of the conterminous United States [ More info] Geochemical and mineralogical maps along with a histogram, boxplot, and empirical cumulative distribution function plot for each element or mineral whose data are provided in DS-801
Summary of estimated water use in the United States in 2010 [ More info] About 355,000 million gallons per day of water was withdrawn for use in the United States during 2010, a decline of 13 percent from 2005 and a substantial change from the level of about 400,000 reported from 1985 to 2005.
Assessment of undiscovered oil and gas resources of the Anadarko Basin Province of Oklahoma, Kansas, Texas, and Colorado, 2010 [ More info] We estimated mean technically-recoverable undiscovered continuous and conventional resources that total 495 million barrels of oil, 27.5 trillion cubic feet of natural gas, and 410 million barrels of natural gas liquids in this area.
Assessing the vulnerability of public-supply wells to contamination--Edwards aquifer near San Antonio, Texas [ More info] Well vulnerability results from the young age of groundwater. Karst features permit contaminants to move into the aquifer easily, leading to a well mixed aquifer; geochemical processes do not degrade contaminants quickly.
Occurrence, distribution, and concentrations of selected contaminants in streambed- and suspended-sediment samples collected in Bexar County, Texas, 2007-09 [ More info] Study showing which chemicals found in sediments were most common, with methods used and likely consequences of their high concentrations.
Assessment of potential coastal impacts: Hurricane Rita [ More info] Areas susceptible to inundation during landfall of Hurricane Rita are assessed by comparing lidar-derived dune elevations to simulated storm surge values. Results shown on pictorial maps.
Evaluating the variability of sediment and nutrient loading from riverine systems into Texas estuaries and bays [ More info] Some results from a study of the variability of sediment and nutrient loads in the lower reaches of the Trinity River during a variety of hydrologic conditions.
