Understand and forecast long-term variations of in-situ geophysical and geomechanical characteristics of degrading permafrost in the Arctic – continuously observed ground vibration using Distributed Acoustic Sensing, Utqiaġvik, Alaska, 2021–2022

This dataset provides distributed acoustic sensing (DAS)-derived axial strains of a ~2 km (kilometer) fiber-optic cable in permafrost terrain near Utqiaġvik, Alaska, during October 2021 to September 2022. The dataset establishes a baseline for assessing cryoseismic activity and dynamic near-surface vibration in Arctic permafrost and supports broader investigations of geophysical and geomechanical processes in Arctic permafrost environments using distributed fiber-optic sensing.
