Once an iceberg breaks off the Antarctic ice sheet, its rate of travel is determined by the current in the Southern Ocean that picks up the berg.

On land, there is movement in the ice of the ice sheet, and in some locations, several feet per day.

According to the CalTech Scientist Barclay Kamb,

"At a camp on Ice Stream B called Upstream Bravo, where we have been working, the ice is moving 1.2 meters per day, and farther downstream its speed increases to more than 2 meters per day. The ice outside the ice Stream is moving only a few meters per year."
