In all my life, I have never heard of the environmental phenomena of the wind driving ice sheets ashore, especially in May! It's not even windy where these people are. The ice sheet, which seem rather porous, pulses forward, creating odd sounds. I would think that the friction involved (both internally and with the ground) would be rather high. I would never have imagined this. It looks like something out of a cheap horror film ... like a bizarre, frozen tsunami. I first came across this on the BBC news website. This happened Saturday 11 May.
Is anyone familiar with this? How common is it? How can the forces be transmitted through the ice sheet?
