The UTM stake grid (stakes are in a grid at every 100 meters) was used to locate the points . All measured depths are in cm. Measurements are made within a 20 cm radius of each location point. All the measurements are then averaged into a single value for the day. 2003_present_Imnavait_Thaw_Kling - Starting in 2003, thaw depth has been measured in the Imnavait Creek watershed on a weekly to biweekly basis during the summer season. 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.
