Seasonal water table depth measurements were collected during the 2018 growing seasons at each Mobile Instrumented System Platform (MISP) located at Utqiaġvik (formerly Barrow), Alaska as well as in Atqasuk, Alaska. If a uniform representation of the water table within each plot was visible, then a WTD (water table depth) tube was placed there to measure the change in water table throughout the season. One water table depth measurement was acquired, the date, start and end times, and the people present were also recorded, at alternating grid meters. Water table depth was taken on the north side of the grid at each WTD tube 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.
