Seasonal active layer depth from a Mobile Instrumented System Platform (MISP) grid, Barrow, Alaska, 2016

Seasonal active layer depth measurements were collected during the 2016 growing season at each Mobile Instrumented System Platform (MISP) grid meter in Utqiaġvik (formerly Barrow) Alaska. At each meter two depth measurements were acquired, the date, start and end times, and the people present were also recorded. Depth measurements were taken on the north side of the grid 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.
