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, basal motion, ice deformation, surface velocities, surface mass balance, and changes in surface elevation and terminus position. Data was collected from spring 2014 through fall 2016. The project consisted of time-lapse photography, borehole instrumentation, GPS surveys, active seismics, and basic meteorological measurements. All field work was conducted close to the glacier terminus. This data set contains photos from several time-lapse cameras to document sediment deformation and the seasonal advance and retreat of the glacier's terminus. The time-lapse interval of the cameras varied, but was typically set at 1 hr. Two cameras were kept at fixed locations and operated for more than 1.5 years; the remaining cameras were positioned at different locations each summer.
