Short summary

Cook Glacier, as one of the largest in East Antarctica, may have made significant contributions to sea level during past warm periods. However, despite its potential importance there have been no long-term observations of its velocity. Here, through estimating velocity and ice front position from satellite imagery and aerial photography we show that there have been large previously undocumented changes in the velocity of Cook Glacier in response to ice shelf loss and a subglacial drainage event.
