We estimated means of 940 million barrels of oil, 38.2 trillion cubic feet of gas, and 208 million barrels of natural gas liquids in these units using a geology based assessment methodology.
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.
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.
Research and development efforts to improve our ability to provide scientific information needed by local beach managers faced with questions about environmental quality and possible beach closure or resource usage.
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.
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.
The Great and Little Miami River Basins form a National Water Quality Assessment (NAWQA) Program study unit for studying the status, trends, and changes affecting the nation's water quality. Site links to data, publications, maps, and results.
Explains how this important indicator bacteria is used to detect problems in the water supply that may affect human health, focusing on a specific recreational area.
Overview of microbiology projects related to water quality investigating bacteria, viral and protozoan pathogens and indicators in the environment with links to publications, analytical and field methods, laboratory, and current projects.
Information on the Gap Analysis Program in Ohio, a geographic approach to planning for biological diversity by mapping native aquatic and terrestrial animal species and natural communities on present-day conservation lands.
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.

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.
Upcoming interagency study to assess status of ecological conditions, their relationships with contaminants and nutrients, anthropogenic factors affecting these, and develop models that may predict these ecological conditions.
Explains the characteristics and history of this distinctive way of describing geographic position characteristic of the midwestern and western states of the US.
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.
Listing of USGS research and monitoring projects on mine drainage, in order to promote cooperation and collaboration among scientists working on problems related to mining and the environment.
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.
The Marcellus shale is a black shale unit in the eastern US. It has economic use as a source of natural gas. Environmental concerns arising from the process of exploiting this resource include water supply and wastewater disposal.
