More about ERMA®
Hundreds of GIS layers are freely available on NOAA's Pacific Northwest Environmental Response Management Application® (ERMA) mapping site, published by the NOAA Office of Response and Restoration. The Puget Sound Institute is collaborating with NOAA to add map layers and GIS data to Pacific Northwest ERMA®. The goal is to map Puget Sound and Salish Sea ecosystem data, analysis and research.
