Atlantic ERMA

Atlantic ERMA®, an online mapping tool for the Atlantic coast, is a collaborative effort between NOAA and the U.S. Environmental Protection Agency to integrate key environmental response information for decision makers. ERMA gathers a variety of data into a single interactive map, providing a quick visualization of an emergency situation and improving communication and coordination during potential response and restoration activities.

In 2007, ERMA began as a pilot project in Portsmouth, New Hampshire. It was eventually expanded to all New England and Atlantic states, where it has been used to assist response efforts during Hurricane Irene in 2011 and the Spill of National Significance exercise in 2010.

In the fall of 2012, Atlantic ERMA was put to the test during the aftermath of Post Tropical Cyclone Sandy. Designated as the Common Operational Picture for the U.S. Coast Guard's pollution response to Sandy, ERMA provided responders across multiple command posts and field teams with up-to-date information to facilitate assessment and cleanup of spilled hazardous waste and other pollutants. Data specific to the response included identified pollution sources, remote sensing imagery, field and overflight photos, major response operations, and locations of sensitive natural resources.

Atlantic ERMA will continue to support ongoing environmental remediation and restoration activities throughout this region.

More Information about ERMA

ERMA is designed to:

  • Aid in spill preparedness and planning.
  • Assist in coordinating emergency response efforts and situational awareness for human and natural disasters.
  • Help define the extent of potential environmental impacts, supporting the Natural Resource Damage Assessment process.
  • Support ecological recovery and restoration efforts.
  • Provide access to hazard-related information from anywhere you have an internet connection.
  • Visualize data from a variety of sources, with the ability to include additional media such as photos and links to scientific reports.
  • Allow you to customize the data displayed, so you see only the information needed to make a specific decision or action plan.
  • Tell a story or reconstruct the history of an event using animated layers of information.

The application has been customized with specific data for 10 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.
