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.
