This data set includes measurements and observations taken from drained thaw-lake basin (DTLB) cores retrieved from Barrow and Atqasuk, Alaska in April and August of 2001 through 2003. Investigators selected young, medium, old, and ancient DTLBs to collect data from by surveying their vegetation. DTLBs become sites for the accumulation of organic carbon as peat deposits. With this research, investigators aimed to estimate the amount of carbon sequestered in drained basins, supplement current knowledge of the basic processes governing these important elements of the northern Alaskan landscape, and provide new information on landscape-scale response to climate change.

Investigators collected data biannually, each April and August from 2001 to 2003.
Soil cores were collected using a 7.5 cm SIPRE auger barrel powered either by a standard posthole digger or a Big Beaver earth drill. The processing of the soil cores is discussed in the file PROCESSING_PERMAFROST_CORES.doc available via FTP. Investigators recorded data on the form Rev_Form_DTLB_Coring.xls. Laboratory analyses followed the protocol established by the USDA Natural Resources Conservation Service (1996).
