These data are from a study of the origin and associated geomorphological, ecological, and pedological processes of thaw-lake basins of the Arctic Coastal Plain, Alaska. The research utilized high-resolution multispectral satellite data, ground-penetrating radar, and extensive coring to estimate the amount of carbon sequestered in the drained basins. Investigators used radiometric dating, microfossil analysis, and soil development to determine whether carbon accumulation rates respond to regional changes in climate, or if they are influenced by local rates of plant succession.

Investigators reported depths, adjusted depths, radiocarbon dates, calibrated radiocarbon dates, pollen, microfossils, soil bulk density, total organic carbon (TOC), and other descriptive statistics from the spring and summer seasons of April 2002 through April 2005. Data are in Microsoft Excel, Microsoft Word, TIFF, JPEG, and ArcView Shapefile formats, available via FTP.
