Unified Interior Regions

The USGS has just completed a geologically based assessment of the technically recoverable, undiscovered oil and gas resources of the Appalachian Basin Province. This area includes parts of New York, Pennsylvania, Ohio, Maryland, West Virginia, Virginia, Kentucky, Tennessee, Georgia, and Alabama.

Canus, a one-winged whooping crane instrumental in re-establishing this endangered species as part of the United States Geological Survey’s (USGS) captive breeding program, died last weekend of natural causes at the agency’s Wildlife Research Center in Patuxent, Maryland.

The wild whooping crane that had been shot in Kansas and transported to the USGS-Patuxent Wildlife Research Center in Laurel, MD, for recovery, died overnight. The endangered bird was being treated for shotgun wounds, including a broken wing, and a respiratory condition.

Coal provides more than half of our Nation’s electrical energy needs. For more than three centuries, coal has been mined in the Appalachian Basin, one of the most important coal producing regions in the world. This area includes parts of Ohio, Pennsylvania, West Virginia, Kentucky, Virginia, Maryland, and Tennessee. Almost all of the coal now mined in the Appalachian Basin is used in eastern state

By using electrical measurements, USGS scientists have detected fresh groundwater in submarine environments in Mid-Atlantic coastal waters. The new data will help define sources and quantities of nutrients entering the coastal bays of Delaware, Maryland, and Virginia and refine groundwater flow models.

The United States and the People’s Republic of China share a common problem ? elevated nitrate concentrations in water supplies used for drinking water, according to a recently released report by the U.S. Geological Survey (USGS). While elevated concentrations of nitrate in water have been known to cause illness in babies, there is also indirect evidence that they can cause cancer. 

What happens when a rock from space that’s more than a mile wide slams into the Earth at supersonic speed? Scientists from the U.S. Geological Survey (USGS) and its partners are learning as they analyze evidence they are recovering from cores drilled during the past two summers into the Chesapeake Bay impact crater and surrounding structures.

March will mark the beginning of a new field season for scientists from the U.S. Geological Survey (USGS) and its cooperators who will begin drilling a second core hole into an impact structure created 35 million years ago when an asteroid or comet slammed into the ocean near the present-day mouth of the Chesapeake Bay.
