The archive includes lake-sediment chronologies, macroscopic charcoal, geochemical data (XRF, XRD, LOI, MS, isotopes), and/or water chemistry measurements from twelve lakes in tundra ecosystems in Alaska, associated with NSF grant ARC-1023477 (Feng Sheng Hu, PI). All datasets are in csv format (converted from original excel xlsm workbooks). Each lake has metatdata in the first tab that contains information on associated publications, lake location, water depth at the coring location, ecoregion, sediment-core length, and age span of sediments. These data are from lakes located in the following Alaskan tundra ecoregions: Noatak River Watershed, Yukon-Kuskokwin Delta, northern and southern areas of the Brooks Range, and the Arctic Foothills. Detailed methodological information can be found in the associated publications.
