Iceberg B-17B was an iceberg twice the size of Manhattan, that floated in the Southern Ocean approximately 1700km (1,100miles) off the coast of Western Australia. Iceberg B-17B measured approximately 140km2.[1] B-17B originated in the first half of 2000 when the iceberg B17 split into two parts. B17 itself had broken off from the Ross Ice Shelf two months before.[2]
In mid-December 2009 the Australian Bureau of Meteorology issued a warning to users of shipping lanes in the area.[3] [4] By the 31st of that month the main body of the iceberg had broken into three pieces.
