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 Marine Cadastre National Viewer is a joint product of the U.S. Bureau of Ocean Energy Management (BOEM) and the National Oceanic and Atmospheric Administration (NOAA). The viewer contains an enormous amount of information relevant to marine and coastal issues in interactive map form. Over 275 different map layers are available on a wide range of topics. The geoscience-related layers include:
The National Oceanic and Atmospheric Administration's Sea Level Rise and Coastal Flooding Impacts data viewer provides a preliminary look at how different amounts of sea level rise would affect coastal flooding in the United States.
In addition to overall flooding estimates, users can see the relative social vulnerability of coastal regions; areas currently already subject to coastal flooding; impacts on marshes; and the different levels of confidence with which predictions can be made in different areas.
