We estimated the volume of oil, natural gas, and natural gas liquids in three closely related geologic units in this area using a geology based assessment methodology.
Report prepared for the U.S. Fish and Wildlife Service with descriptions of exotic aquatic species introduced in the southeast United States with information on populations, geographic distribution, and origins.
Consistent, historic, and up-to-date ground-water data, such as water levels collected at wells and springs, are available from the USGS National Water Information System as graphs, tables, or files to download.
Consistent, historic, and up-to-date surface-water data, such as gage height (stage) and streamflow (discharge), collected at major rivers, lakes, and reservoirs, downloadable from the USGS National Water Information System as graphs, tables, or files.
Consistent, historic, and up-to-date water-quality data, such as temperature, specific conductance, pH, nutrients, pesticides, and volatile organic compounds downloadable from the USGS National Water Information System as graphs, tables, or files.
Consistent, real-time water data from streams, lakes, reservoirs, ground-water, and meteorological sites, are available from the USGS National Water Information System as graphs, tables, or files to download.
We estimated mean volumes of 38 trillion cubic feet (TCF) of undiscovered natural gas, 159 million barrels of natural gas liquid (MMBNGL), and no oil in accumulations of 0.5 million barrels (MMBO) or larger in this area.
Science issues in this area identified by USGS and its partners, including regional goals and objectives, threats and emerging issues, and information gaps
Describes the analytical process by which spatial scientific information contributes to forecasts and models in support of regional and local decision-making.
Locations for nine species of large constrictors, from published sources, along with monthly precipitation and average monthly temperature for those locations. Shapefiles for each snake species studied.
We estimated means of 147.4 trillion cubic feet of undiscovered natural gas, 2.4 billion barrels of undiscovered oil, and 2.96 billion barrels of undiscovered natural gas liquids in this area using a geology-based assessment methodology.
We estimated a mean of 4.06 trillion cubic feet of undiscovered, technically recoverable natural gas in these coal beds of the onshore lands and State waters of the Gulf Coast.
We estimated mean undiscovered resources of 113.7 trillion cubic feet of natural gas, a mean of 690 million barrels of oil, and a mean of 3.7 billion barrels of natural gas liquids in onshore lands and state waters in this area.
Describes a national reconnaissance study of reproductive health in two species of fish across the US. More than 2,200 common carp and 650 largemouth bass were collected at 119 rivers and streams.
Explains the characteristics and history of this distinctive way of describing geographic position characteristic of the midwestern and western states of the US.
Estimates of change in major types of land use and land cover from 1973 to 2000 should help model potential future change as climate, population, public policy, and technology change.
Mathematical model of the groundwater system in this area includes 13 types of data and spans multiple aquifers over more than a century. This enables us to assess the quantity of groundwater, where and how it is being used, and how pumping affects it.
This updated subset of USGS streamgages for which the streamflow primarily reflects prevailing meteorological conditions for specified years, screened to exclude sites where human activity affects the natural flow of the watercourse.

We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
Water levels in wells completed in the Mississippi River Valley alluvial aquifer and the Sparta aquifer in eastern Arkansas respond to variability associated with annual precipitation.
