DESCRIPTION:Ice loss from the West Antarctic Ice Sheet is a significant co
 ntributor to sea-level rise. The ice loss is thought to have been triggere
 d by fluctuations in the delivery of oceanic heat to the base of ice shelv
 es. However\, the response of ice sheets to ocean variability remains poor
 ly understood. Applying a novel synchronously coupled ice-ocean model\, th
 is study considers the response of an ice sheet to periodic variations in 
 ocean forcing. The results show that the amplitude of oscillations in grou
 nded ice volume grow as a non-linear function of ocean forcing period. Thi
 s implies that slower oscillations in climatic forcing are disproportionat
 ely important to ice sheets. The residence time of ice shelves offers a cr
 itical time scale\, above (below) which the ice response amplitude is a li
 near (quadratic) function of ocean forcing period. These results highlight
  the sensitivity of West Antarctic ice streams to perturbations in heat fl
 uxes occurring at interannual and decadal time scales.
