Borehole tiltmeter and water pressure data for Athabasca Glacier, Alberta, Canada (2022-2023)

Research on Athabasca Glacier in the late 1960s constrained ice column deformation rates using borehole inclinometry techniques (Raymond, 1971). This study sought to conduct a field campaign to estimate modern ice deformation rates using an array of 3-axis tiltmeters deployed in Athabasca Glacier. In July 2022, 12 boreholes were drilled to the bed of Athabasca Glacier and instrument strings of three-axis tiltmeters and pressure transducers were deployed at varying depths. The three-axis accelerometers and magnetometer data from these instruments allow for calculation of sensor azimuth and inclination through September 2023. Basal water pressure from sensors with pressure transducers is also reported for this observational period.
