Macrofossil, peat composition, LOI, radiocarbon, and permafrost data from a drained thermokarst lake, Old Crow Flats, Yukon

Peat and soil samples were collected at the end of August 2022 from the margin and centre of a drained thermokarst lake basin in Old Crow Flats, Yukon, Canada. Samples were collected to reconstruct local vegetation histories based on macrofossil records, with selected samples from specific stratigraphic levels subjected to radiocarbon dating.

Peat samples were collected as vertical profiles down to the basal layer. These included peat monoliths and frozen peat cores if the basal layer was below the permafrost table. Soil samples were also collected below the basal layer to characterize the pre-drainage conditions.
