Imnavait Watershed Thaw Depth Survey Summary for 2003 to 2009, Arctic LTER, Toolik Research Station, Alaska.

Thaw depth measurements in the Imnavait Creek watershed from 2003 to 2009. Depths were measured weekly to biweekly during the summer season, June to late August. A ruled stainless steel rod was inserted in non tussock microhabitat until the frozen layer was reached, and the distance was measured to the top of the organic mat (beneath the uppermost moss). Three measurements were made at each point, and were made within a 20 cm radius of each location point.
