(907) 474-6242 (907) 474-7872 Associated investigator 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

While metadata will be freely available to those requesting it, the data manager will assure that any restrictions on access to data sets in the database will be enforced. Data will not be released without proper permission first being obtained from the investigator who generated the data.

Researchers should receive adequate acknowledgment for the use of their data by others and should be provided with copies of publications using their data. Users of data from the data base must be aware that data is not to be sold or redistributed.

It is considered a matter of professional ethics to acknowledge the work of other scientists. Thus, the Data User will properly cite the Data Set in any publications or in the metadata of any derived data products that were produced using the Data Set.
