| Summary: | Seasonal soil temperature measurements were collected during the 2018 growing season at each Circumpolar Active Layer Monitoring (CALM) grid subset plot (30) and at each Mobile Instrumented System Platform (MISP). Both of these grids are located at Utqiaġvik (formerly Barrow), Alaska as well as in Atqasuk, Alaska. For CALM measurements, 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. For MISP measurements, at each grid meter one soil temperature measurement was acquired, the date, start and end times, and the people present were also recorded. Soil temperature 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.
