Gulf of Mexico ERMA

Created in 2012, Gulf of Mexico ERMA® is an online mapping tool that integrates key information to support environmental and severe-weather responses in the Gulf of Mexico. Gulf of Mexico ERMA does not include data related to the 2010 Deepwater Horizon/BP oil spill, which instead can be accessed via the ERMA Deepwater Gulf Response site.

During the Hurricane Isaac response in 2012, NOAA GIS specialists incorporated real-time weather conditions, pollution locations, and overflight survey paths and photos into Gulf of Mexico ERMA. In addition, the site houses digital Area Contingency Plans and oil infrastructure data for the region, which enables responders to quickly access relevant information during hurricanes or oil spills. By gathering this data into a single interactive map, it provides decision makers with a quick visualization of an emergency situation and improves communication and coordination during potential response and restoration activities.
