Where was the largest iceberg ever discovered and what sort of lifespan would such an iceberg be expected to have?

The most massive icebergs tend to come from the Antarctic, whilst some of the tallest are found off the Arctic. I'm not sure about the biggest of all time, but since it became possible to measure them scientifically the largest iceberg has been B15 (4,181 sq. miles) which calved off the Ross Ice Shelf in Antarctica in March 2000. This was just a little smaller than Connecticut. After a few days it broke into two parts, named B15A and B15B. B15B floated away and later shattered into numerous smaller pieces. According to what I have read (which is more than a year out of date) B15A, now generally called B15, is stuck near the entrance to McMurdo Sound. I think I'll have to leave life span to someone else. It must depend on where they float to, and how warm the water and the air temperature gets, though plainly these monsters contain so much ice that they will last many years. Jul 26 04, 5:25 AM
