Imnavait Watershed Thaw Depth Survey Summary for 2003 to 2024, Arctic LTER, Toolik Research Station, Alaska.

Thaw depth was measured using a steel probe in the Imnavait Creek watershed, near Toolik Lake, Alaska. The thaw grid includes measurements made from the valley bottom (on both sides of the stream), up the hillslope. The thaw grid is near Imnavait water tracks 7 and 8, and measurements have been made from the 2003 season until present. At least two surveys are conducted each summer, on 2 July and on 11 August (plus or minus a couple of days on either side of those dates).
