Active layer thickness and ground temperatures, Svea, Svalbard, Version 1

Snow and soil temperature records for January 1988 - May 1996 are presented. Included are snow depth and weight measurements, snow density (calculated), active layer depth in the frost tubes, weight of wet and dried soil samples from unknown depth within the active layer (water content calculated), and soil temperature at the surface (0.05 cm) and to the depths of 3 to 4 meters at 3 sites. The sites are 1) on a road covered by 1 m of gravel underlain by clay; 2) outside a building on piles, (sensors are placed 1 to 2 m from the building wall); and 3) under the building between piles. In addition, air temperature was measured inside the building or between the piles (documentation is not clear on this point.) There are several gaps in temperature measurements (January 1991 to May 1992). These data are presented on the CAPS CD-ROM version 1.0, June 1998.

Air temperature, wind direction, and temperature were measured at 5, 20, 50, 100, 150, and 200 cm below the tundra surface at an undisturbed site; and at 5, 20, 50, 100, 150, 200 cm, and 3 m and 8 m below the concrete surface of a building. Incoming radiation, outgoing radiation, temperature of the heat flux instrument, global radiation, heat flux, wind speed, wind speed maximum, average wind speed, and temperature inside the building were measured since 1993 with data loggers. All data are recorded for July 1987 - February 1996.

(Data obtained and submitted by Odd Gregersen and Steinar Bakkehoi, digitized by M.O.Leibman).

Snow and soil temperature records for January 1988 - May 1996 are presented. Included are: snow depth and weight measurements (calculated from a 10 sq.cm sample), active layer depth in the frost tubes, weight of wet and dried soil samples from unknown depth within the active layer. Water content was calculated as (wet soil weight-dry soil weight)/wet soil weight. Also included is soil temperature at the surface (0.05 cm), and to the depths of 3-4 m at 3 sites: on a road covered by 1 m of gravel underlaid by clay (in the database referred to as "gravel"), outside the building on piles, 1-2 m from the wall (in the database referred to as "outside"), and under the building in between the piles (in the database referred to as "inside"). In addition, air temperature measured inside is included. There are several gaps in temperature measurements (January 1991 to May 1992).

Weather station data is available in hard copy: precipitation records and snow depth records for 1985-1996.
