(907) 474-6242 (907) 474-7872 Associated party 2005-11-21 This data set contains active layer depth measurements (cm) for a transect from the center of the BBC collapse scar (0 m) into the surrounding fire scar (30 m) of the Survey Line Fire (burned in June-July 2001). Data were collected using a 120m (and during 2004 a 205.5 m) permafrost probe at every visit to the site in 2003 and 2004. Three permafrost depth measurements were made within a 25cm radius at every point along the transect (0, 3, 6, 9, 12, 15, 18, 21, 24, 27, and 30 m on the east and west sides of the boardwalk and at 33 m on the west side only). This data set was collected to monitor the increase in active layer throughout the growing season to relate this to measured fluxes of CO2 and CH4 emissions from soils along the same transect. The data set was also used to monitor permafrost collapse at the margins of the BBC collapse scar. disturbance permafrost soil temperature Climate

BBC collapse scar -- The BBC collapse scar is located in Interior Alaska, USA, adjacent to the Bonanza Creek LTER on the south side of the Tanana River, approximately half way between Fairbanks and Nenana. The scar is located 0.5 km south of the river bank in a low lying black spruce tussock dominated wetland that was burned in June-July 2001 by the Survey Line fire. .
