The US Geological Survey (USGS) performs scientific analysis and monitoring of natural resources throughout the country. The agency, which consists of about 10,000 scientists and technicians at more than 400 locations across the country, manages water, energy, biologic, and mineral resources and shares its data with the scientific community and the general public.
USGS also provides scientific services internationally to about 100 countries. In 2007 it developed a science strategy to study climate variation, ecosystems, natural hazards, and wild-animal diseases in addition to its traditional areas of focus. A part of the US Department of the Interior, USGS was established in 1879.
