Transcript for Drift Ice as a Geologic Agent, segment 10 of 11


{{{Background noise}}}

The combined impact of ice-related sedimentary processes discussed in this videotape is largely responsible for very high rates of coastal retreat and for shelf erosion in the Arctic. Seasonal changes and related storm events drive the system by creating, moving, and destroying ice. Quantifying the role of ice in moving sediment remains a very complicated task. Nevertheless, under today's relatively warm conditions and probably had a wider global impact in the past.
