Figure 3: Longitudinal sectors defined to distinguish regions of ice-sheet change.

Sectors are simply defined by longitude, as follows: MBL/ASE (Marie Byrd Land/Amundsen Sea Embayment) (160° W–60° W), Recovery Basin (60° W–30° E), Aurora Basin (30° E–135° E), Wilkes Basin (135° E–160° E) and Ross Basin (160° E–160° W). These are used for the model ocean and land surface calculations plotted in Figs 4 and 5. Text colours correspond with Figs 4 and 5 graphs. A separate sector was considered focusing on the Lambert Glacier/Prydz Bay area, but the model showed little net emerged coastal area, due to the prevailing steep-walled fjord-like geometry.
