Seasonal change in Antarctic ice sheet movement observed

Some estimates of Antarctica's total contribution to sea-level rise may be over- or underestimated, after researchers detected a previously unknown source of ice loss variability. The researchers identified distinct, seasonal movements in the flow of land-based ice draining into George VI Ice Shelf -- a floating platform of ice roughly the size of Wales -- on the Antarctic Peninsula.
