World Icebergs: The Largest Iceberg of Jamaica


>

Iceberg B-15 was the largest ever recorded iceberg. It had an area of 3,100 km², making it larger than the island of Jamaica, and was created when part of the Ross Ice Shelf broke off in March 2000. In 2003, it broke apart, and one of the larger pieces (called B-15a) drifted north, eventually smashing into a glacier in 2005, breaking off an 8-km² section and forcing many antarctic maps to be rewritten. 

It drifted along the coast and eventually ran aground, breaking up once again. In 2006, a storm in Alaska (that’s right, Alaska) caused an ocean swell that travelled 13,500km, over 6 days, to Antarctica and broke up the largest remaining part even more. 
Almost a decade on, parts of the iceberg have still not melted, with the largest remaining part, still called B-15a, having an area of 1,700 km². The picture above shows B-15a (top left) in 2005, after drifting west into the Drygalski Glacier (bottom), breaking the end off into several pieces.
