Nikolay Shiklomanov The Atqasuk site is located along the Meade River on the inner Arctic Coastal Plain, approximately 100 km inland. The 1-km2 grid is situated on an ancient sand sea [Everett, 1980; Carter, 1981] developed on a 1% northfacing slope. A lake occupies a portion of the northeastern quadrant, and the well-drained sandy higher slopes are characterized by moist acidic tundra. A 1 x 1 km2 grid of precisely surveyed stakes at 100-m intervals was established at Atqasuk in 1995 under the auspices of the U.S. National Science Foundation’s Arctic System Science (ARCSS) program. Simultaneous measurement of air and shallow ground temperature has been operating continuously at the site since 1994. that of other sites in the Alaska CALM network (Hinkel & Nelson, 2003).

To ensure relative consistency within the record, end-of-season measurement dates are within the same Julian calendar week during the height of the thaw season (mid-August to mid-September).
