Bonanza Creek LTER: Annual Active Layer Depths at Core Floodplain Sites from 1975 to Present in the Bonanza Creek Experimental Forest near Fairbanks, Alaska
Annual thaw depths are measured at the time of maximum thaw at any of the 35 BCEF-LTER sites that have permafrost or intermittent seasonal frost. 1. Wildfire in the black spruce permafrost sites will cause an increase in the active layer thickness and subsidence of the surface layers that may last f...
