I wonder what the mass balance picture looks like when you add in the glaciers on land behind the ice sheets. It seems plausible that the ice shelves that seem be be stable or growing in size may be doing so simply because glaciers are moving out to sea faster than the edge of the ice shelves are calving, but I don't know if that effect is larger or smaller than the accumulation of new ice on the shelves.
