The Arctic Environmental Response Management Application (ERMA®) is a web-based Geographic Information System (GIS) tool that assists emergency responders and environmental resource managers in dealing with incidents that may adversely impact the arctic environment. Arctic ERMA integrates various real-time and static datasets into a single interactive map to provide a visualization of the situation and improve communication and coordination among responders and stakeholders.

The Arctic ERMA was officially launched in July 2012 and is one of eight regional ERMA projects in the U.S. Arctic ERMA was designed as a tool for the Arctic's distinctive conditions, considering variables such as the extent and concentration of sea ice, locations of ports and pipelines, and vulnerable environmental resources.

The launch of Arctic ERMA is part of ongoing efforts by the Interagency Working Group on Coordination of Domestic Energy Development and Permitting in Alaska, which President Obama established in July 2011. This working group aims to coordinate the federal agencies responsible for overseeing the safe and responsible development of onshore and offshore energy in Alaska.


Arctic ERMA is administered and funded primarily by the National Oceanic and Atmospheric Administration (NOAA) Office of Response and Restoration (OR&R), but many organizations were integral in the development of the Arctic ERMA and continue to contribute to its operation:

Datasets and Applications

Presently, Arctic ERMA is comprised of over 500 data layers. Examples of available datasets include weather and oceanographic information, ice extent and concentration, nautical charts, ship locations, locations of infrastructure and equipment, environmental sensitivity data, habitat locations, bathymetry, oil infrastructure, critical areas for marine mammals/birds, and satellite information.

Arctic ERMA was already in use before its official launch. In 2010, ERMA was used to monitor and prepare for a spill from the M/V Golden Seas near the Aleutian Islands. In January 2012, it was used to monitor and provide information to the State of Alaska for the U.S. Coast Guard Healy and Russian tanker Renda's fueling operation to Nome.

Since its official launch, it has been used in a few arctic exercises including an industry-sponsored training simulation of an oil spill in the Chukchi Sea in the summer of 2012. Arctic ERMA was also used to monitor the drill rig Kulluk for several days following 31 December 2012 when it ran aground near Kodiak Island. Over the past year, ERMA has been used to show where potential marine debris from the Japan tsunami has impacted Alaskan shores.

Future Plans

Future plans for Arctic ERMA consist of adding data (including local knowledge), keeping all data layers current, and continuing to ensure all metadata are compliant for public release of datasets. There are efforts to move the website into a government domain on cloud-computing resources. Also, this summer the stand-alone ERMA prototype will be completed with the capability of re-syncing once Internet access is secured at a field site.
