Who We Are

Created by an act of Congress in 1879, the USGS provides science for a changing world, which reflects and responds to society’s continuously evolving needs. As the science arm of the Department of the Interior, the USGS brings an array of earth, water, biological, and mapping data and expertise to bear in support of decision-making on environmental, resource, and public safety issues.

The U.S. Geological Survey works with many partners to provide objective and impartial science to resource managers, emergency response, and the public.
