ERMA® is an online mapping tool that integrates both static and real-time data, such as Environmental Sensitivity Index (ESI) maps, ship locations, weather, and ocean currents, in a centralized, easy-to-use format for environmental responders and decision makers. ERMA enables a user to quickly and securely upload, manipulate, export, and display spatial data in a Geographic Information System (GIS) map. Developed by NOAA and the University of New Hampshire with the U.S. Environmental Protection Agency, U.S. Coast Guard, and U.S. Department of Interior, ERMA provides environmental resource managers with the data necessary to make informed decisions for environmental response.

NOAA has nine ERMA sites customized for various U.S. regions, each of which is kept up-to-date with basic information available around the clock and is publicly available.
