Basal mechanics of ice streams: Insights from the stick-slip motion of Whillans Ice Stream, West Antarctica
The downstream portion of Whillans Ice Stream, West Antarctica, moves primarily by stick-slip motion. The observation of stick-slip motion suggests that the bed is governed by velocity-weakening physics and that the basal physics is more unstable than suggested by laboratory studies. The stick-slip...
