Abstract
Mass loss from the Antarctic Ice Sheet is dominated by ice dynamics, where ocean-driven melt leads to un-buttressing and ice flow acceleration. Long-term ice speed change has been measured in Antarctica over the past four decades; however, there are limited observations of short-term seasonal speed variability on the grounded ice ... read more
