The Environmental Response Management Application (ERMA®) Gulf Response is an online mapping tool that provides you with up-to-date information about the spill response effort in the Gulf of Mexico. Developed by NOAA with the U.S. EPA, Coast Guard, and the Department of Interior, this site offers a visual and centralized means of accessing spill response information. It represents the federal government's commitment to providing clear and transparent information on the 2010 Deepwater Horizon/BP oil spill.

The tool integrates the latest response data related to the oil spill, such as scientific samples and information on wildlife and other Gulf Coast resources into one customizable, interactive map. ERMA Gulf Response also integrates real-time information such as weather conditions, tide and currents, and vessel locations.

ERMA Gulf Response is the public version of ERMA developed by NOAA and the University of New Hampshire's Coastal Response Research Center. ERMA was designed to facilitate communication and coordination among a variety of users—from federal, state, and local responders to local community leaders and the public. Click the map below to use the tool yourself and see both current and historical data about the oil spill, as well as shipping information, past fishery closures, and locations where responders are still working.
