Seasonal soil temperatures from a Circumarctic Active Layer Monitoring (CALM) grid, Atqasuk, Alaska, 2016

Seasonal soil temperature measurements were collected during the 2016 growing season at each Circumarctic Active Layer Monitoring (CALM) grid subset plot (30) in Atqasuk, Alaska. At each plot one temperature measurement was acquired, the date, start and end times, and the people present were also recorded. Soil temperature measurements were taken outside of every plot on the northeastern most corner in order to reduce disturbance of vegetation. These measurements are part of the Arctic Observing Network (AON) - International Tundra Experiment (ITEX) initiative and help to document seasonal changes in surface moisture and structure at high spatial scales.
