DESCRIPTION: How climate variability will impact ice mass loss is a key so
 urce of uncertainty in estimates of Antarctica's future contribution to se
 a level rise\, particularly in regions of East Antarctica where there is a
  paucity of long-term climate records. Here\, we use an ice sheet model to
  investigate the impact of ocean variability of varying amplitudes on ice 
 discharge from Totten Glacier. We find that ocean variability has a lesser
  impact on discharge when the background ocean temperatures are close to p
 resent-day observations. For warmer background ocean temperatures\, ocean 
 variability can alternately delay or accelerate grounding line retreat. Ou
 r results show that the amplitude of ocean variability is not a clear pred
 ictor of the ice sheet response\, highlighting the need for long-term ocea
 n state measurements.\n
