This record contains data files and metadata associated with permafrost monitoring in the Central Alaska Network of National Parks. Updated and complete protocol data files, including data from all prior years, are uploaded once per year as a zipped directory labelled with the upload date. Older data uploads are maintained on IRMA as separate records for archival purposes, but the most recent zip file will always contain the most authoritative and updated records. Subdirectories included within each year's entry include: PRM01 (locations) PRM02 (field notes) PRMal01 (active layer survey files) PRMal02 (certified active layer measurements) PRMbh01 (borehole logger files) PRMbh02 (certified borehole temps) PRMrg01 (rock glacier survey files) PRMrg02 (certified rock glacier rasters) PRMst01 (soil temp logger files) PRMst02 (certified soil temps)

These data consist of fully processed permafrost temperature data from borehole logs acquired by the U.S. Geological Survey (USGS) from the 24-element US Department of the Interior (DOI) Global Terrestrial Network for Permafrost (GTN-P) Deep Borehole Array in arctic Alaska beginning in 1973 and ending in 2014. The data represent the true temperatures in the wellbores and surrounding rocks at the time of the measurements.

This dataset provides field observations of thaw depth and dominant vegetation types, a LiDAR-derived elevation map, and permafrost distribution and probability maps for an area on the coastal plain of the Yukon-Kuskokwim Delta (YKD), in western Alaska, USA. Field data were collected during July 8-17, 2016 to parameterize and to validate the derived permafrost maps. The YKD is in the sporadic to isolated permafrost zone where permafrost forms extensive elevated plateaus on abandoned floodplains. The region is extremely flat and vulnerable to eustatic sea-level rise and inland storm surges. These high-resolution permafrost maps support landscape change analyses and assessments of the impacts of climate change on permafrost in this region of high biological productivity, critical wildlife habitats, and subsistence-based human economy.
