Coastal change maps of Bering Land Bridge National Preserve and Cape Krusenstern National Monument, 1980-2014
Swanson DK. 2020. Coastal change maps of Bering Land Bridge National Preserve and Cape Krusenstern National Monument, 1980-2014. Natural Resource Report. NPS/ARCN/NRR—2020/2152. National Park Service. Fort Collins, Colorado
The Bering Land Bridge National Preserve (BELA) and Cape Krusternstern National Monument (CAKR) have about 350 km (220 miles) of coastline. These coastal areas are rich in natural and cultural resources, and they are the most frequently visited parts of the parks. The National Park Service (NPS) Arctic Inventory and Monitoring Network (ARCN) monitors coastal change in BELA and CAKR with aerial photographs and satellite images. Rates of coastal erosion, and associated threats to resources, vary greatly from place to place. A set of 35 maps at a scale of 1:40,000 on 8.5” x 14” pages has been created to portray in detail the rates of coastline erosion or accretion, and areas where vegetation has been gained or lost, in the time period leading up to our most recent imagery of the area, 2013-2014. The maps are available for download in pdf file format from https://irma.nps.gov/DataStore/Reference/Profile/2260273 (Swanson 2020). These maps provide a summary of coastal change that is readily accessible to park managers for assessment of threats to resources. Annotations on the maps highlight significant changes and explain the processes involved.
