This is the field measured snow depth data using an automatic snow depth probe (magnaprobe, Snow-Hydro LCC) in April 20-29, 2019 in North Slope, Alaska. The data are three different format: csv format (comma delimited text format), projected shape file (UTM zone 5), and unprojected shape file (geographical coordinate, WGS 84). The goal of this research project is to quantify the role of thermokarst lake drainage and drained thermokarst lake basin (DTLB) evolution in the arctic system. The joint research team (University of Alaska, Fairbanks and University of Wyoming) traveled over 19 days and approximately 1000 miles in Northern Alaska to make initial geophysical measurement on a range sites. Field work began in mid-April with several days based in Utqiagvik (Western Coastal Plain) in coordination with principle investigator Hinkel and his graduate student Ian Nichols. A group of six then departed for Teshekpuk Lake (Central Coastal Plain), followed by Inigok (Eastern Coastal Plain and Sand Sea), and Oumalik (Loess Belt and Sand Sea) before returning to Utqiagvik in early May. During the travel, manual snow survey was conducted using the mangaprobe to quantify the snowdrift around thermokarst lakes and other land features as complementary to the geophysical and remote sensed snowpack characterizations.
