The data and information provided here reflect a large variety of environmental settings and ecosystems, including the karst geology of the Ozarks and the Appalachians, agricultural regions of the Mississippi Alluvial Plain, the coastline along the Gulf of Mexico, and as of 2018, the U.S. Geological Survey Chesapeake Bay program. On this site, you will find data releases pertaining to the quantity and quality of the surface-water and groundwater resources, aquatic ecology and earth observations collected for studies and/or used in analyses completed by our Center. It is our goal to provide the public with reliable, impartial, timely information and scientific analysis necessary to understand the Nation’s water and ecological resources.
