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.
