Ice-sheet acceleration driven by melt supply variability

  title={Ice-sheet acceleration driven by melt supply variability},
  author={Christian Schoof},
Increased ice velocities in Greenland are contributing significantly to eustatic sea level rise. Faster ice flow has been associated with ice–ocean interactions in water-terminating outlet glaciers and with increased surface meltwater supply to the ice-sheet bed inland. Observed correlations between surface melt and ice acceleration have raised the possibility of a positive feedback in which surface melting and accelerated dynamic thinning reinforce one another, suggesting that overall warming… CONTINUE READING
