This USGS article provides an overview of mapping in the Pribilof Islands. Residual debris sites and areas of soil contamination are the focus of cleanup activities at more than 40 sites on St. George and St. Paul. Restoration efforts on the Pribilofs require samples to evaluate the vertical and horizontal extent of contamination. The locations of these samples, together with those of existing debris fields, cultural features, and natural resources, need to be accurately mapped and recorded to help NOAA successfully track progress on its rehabilitation efforts.
