Southwest ERMA

Southwest ERMA®, an online mapping tool for the coastal California region, gathers a variety of data sets into a single interactive map, providing a quick visualization and improving communication and coordination for environmental response, planning, and restoration. Highlighted data sets include habitats and natural resources at risk, Area Contingency Plans, and real-time weather and operational data.

In the spring of 2013, Southwest ERMA was used in a large-scale oil spill training drill in El Segundo, Calif., just outside of Los Angeles. As the common operating picture for the drill, ERMA allowed all responders to visualize simulated impacts of a potential oil spill in Santa Monica Bay. Southwest ERMA enables NOAA to work more seamlessly with the U.S. Coast Guard and the State of California to share data, be better prepared in case of an actual disaster, and assist in damage assessments and restoration planning.
