Given that calving Patagonia glaciers were far more sensitive to climate fluctuations than western Antarctica, and given the likelihood that paleo sea - ice extent around Antarctica deflected iceberg drift from present pathways, it would be helpful to know how they confirmed the respective continental sources of any dated sediments.

Stresses from ice flowing over bedrock or around islands causes fracturing, and at the front edge of the ice this fracturing leads to iceberg calving.

Ice - sheet volume is controlled by the balance between mass input and mass loss; mass input is almost entirely due to snowfall, and mass loss is from iceberg calving supplied by flow of the ice sheet, or runoff of melt water.

Rapid sea - level rise from these processes is limited to those regions where the bed of the ice sheet is well below sea level and thus capable of feeding ice shelves or directly calving icebergs rapidly, but this still represents notable potential contributions to sea - level rise, including the deep fjords in Greenland (roughly 0.5 m; Bindschadler et al., 2013), parts of the East Antarctic ice sheet (perhaps as much as 20 m; Fretwell et al., 2013), and especially parts of the West Antarctic ice sheet (just over 3 m; Bamber et al., 2009).
