The National Ground-Water Monitoring Network compiles information from over 7,000 groundwater monitoring wells across the country, including Federal, State, and local groundwater monitoring networks. Although the image above only shows the contiguous United States, the interactive map also includes wells from Alaska, Hawaii, Puerto Rico, Guam, and the U.S. Virgin Islands.
The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center in Florida investigates earth-science processes related to coastal and marine environments as well as to societal implications of natural hazards, resource sustainability, and environmental change. The Center is conducting ongoing research in and around the U.S. Virgin Islands that is providing baseline information for resource management and for assessing the health of and environmental changes to vital ecosystems such as coral reefs. In particular, projects are improving the understanding of coral health, advancing the ability to forecast future changes in coral reef ecosystems, and acquiring topographic data for use in inventorying, monitoring, and conserving coastal and marine environments.
