Elevated Soil Temperature and Water Table Manipulation Data from Barrow, Alaska, 1999-2001

Eighteen 60-cm diameter polycarbonate cylinders were installed into the ground at the end of the 1998 growing season when thaw depth was at its seasonal maximum to isolate plots of tundra. The cylinders were organized into three blocks of six for three replicates of the six treatments to be tested.

The six factors tested include: control, elevated water table, lowered water table, elevated soil temperature, elevated soil temperature and elevated water table, and elevated soil temperature and lowered water table. Temperature data were collected from June 1999, until September 2001. Measurements were taken as part of the Land-Atmosphere-Ice Interactions Arctic Transitions in the Land-Atmosphere System (LAII-ATLAS) program.
