Paleoenvironment, Geomorphic Processes, and Carbon Stocks of Drained Thaw-lake Basins in the Arctic Coastal Plain, Alaska, USA, 2002-2005

Summary

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.

Data Acquisition Methods

Investigators used a Big Beaver earth drill equipped with a 7.5 cm diameter Snow, Ice, and Permafrost Research Establishment (SIPRE) core barrel. Total carbon was measured on a Dohrmann DC190 C analyzer. Investigators also used a Global Positioning System (GPS), radiocarbon accelerator mass spectrometry (AMS), and seven Landsat-7 Enhanced Thematic Mapper Plus (ETMP) scenes (Paths 75, 77 and 79 Rows 10 and 11 and Path 81 Row 10).

Derivation Techniques and Algorithms

Refer to Eisner et al., 2005.
