Environmental Response Management Application (ERMA)

The Environmental Response Management Application (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, analyze, 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 the Interior, ERMA provides environmental resource managers with the data necessary to make informed decisions for environmental response.

ERMA is designed to:
  • Visualize information relevant to spill preparedness and planning.
  • Assist in coordinating emergency response efforts and situational awareness for human and natural disasters.
  • Support the Natural Resource Damage Assessment process.
  • Aid in ecological recovery and restoration efforts.

The application has been customized with specific data for eight ERMA sites covering the United States and its territories. ERMA sites have secure-access accounts; however, publicly available environmental and baseline data are openly accessible for all regions.
