Taku Glacier ablation measurements, Alaska. 2014-2016
This project investigated the feedbacks between glacial erosion and glacier dynamics at Taku Glacier, Alaska, which is currently in the advancing phase of the tidewater glacier cycle. We measured the spatial and temporal patterns of sediment erosion, properties of basal till, basal water pressure, b...
