Holocene lake-based Arctic glacier and ice cap records

This data is supplement to "Arctic glaciers and ice caps through the Holocene: A circumpolar synthesis of lake–based reconstructions" and summarizes 66 lake–based records of Holocene glacier and ice cap variations from seven Arctic regions: Alaska (n=6), Baffin Island, Canada (n=5), glaciers and ice caps (GICs) peripheral to the Greenland Ice Sheet (n=22), Iceland (n=5), the Scandinavian peninsula (n=20), Svalbard (n=7), and the Russian high Arctic (n=2) (plus one non-lake record). For each included lake record, glacier and ice cap status is defined in 100–year intervals from 12–0 kiloannum (ka), where 0 = glacially influenced, and 1 = a smaller than present or absent glacier or ice cap. Arctic–wide, the percent of glaciers and ice caps smaller than present or absent is summarized in 100–year intervals from 12–0 ka. Blank cells indicate time periods with no data available, or when the status of the glacier or ice cap was unknown or ambiguous. We assign each record a unique site identifier. See "Site Information" for additional metadata on each record including: region, site # in regional compilations, original reference(s), lake name, glacier or ice cap name, latitude, and longitude.
