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.
About 355,000 million gallons per day of water was withdrawn for use in the United States during 2010, a decline of 13 percent from 2005 and a substantial change from the level of about 400,000 reported from 1985 to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.
Landscape changes in ground disturbance, land use and land cover, condition of forests, temperature, albedo, and others may have effects on the ecosystem that need to be understood as natural resources are discovered and exploited.
Rocks representing a variety of tectonic and depositional environments outcrop along the canal and towpath and reveal the geologic history of the central Appalachian region from the Mesoproterozoic to Jurassic Period.
We estimated a mean undiscovered natural gas resource of 84,198 billion cubic feet and a mean undiscovered natural gas liquids resource of 3,379 million barrels using a geology-based assessment methodology.
