How many feet can the ice-burgs in Antarctica move a year?

The speed at which icebergs in Antarctica move can vary greatly depending on their location, size, and the prevailing ocean currents. In general, most icebergs move at speeds of a few tenths of a mile per year. However, some larger icebergs can move at speeds of up to several miles per year. For example, the B-15 iceberg, which calved from the Ross Ice Shelf in 2000, was about the size of Jamaica and moved at speeds of up to 2-3 miles per year when it was first free-floating.
