Dynamics of subglacial erosion of soft marine sediments and consequences for glacier evolution, Taku Glacier, Alaska, 2014

The purpose of this experiment was to image sediment deposits beneath the Taku Glacier terminus, to determine their thickness and geometry, and to perform Amplitude Variation with Offset (AVO) analysis of seismic reflection returns from the glacier bed to learn the nature of the sediments (dilatant...

Description
Summary:The purpose of this experiment was to image sediment deposits beneath the Taku Glacier terminus, to determine their thickness and geometry, and to perform Amplitude Variation with Offset (AVO) analysis of seismic reflection returns from the glacier bed to learn the nature of the sediments (dilatant and soft vs. dewatered and solid). This seismic reflection survey was part of a larger glacier monitoring project aiming to characterize the relationship between subglacial sediments and the unusual dynamics of the advancing Taku Glacier terminus.
