About

DescriptionIceberg B-9 was an iceberg that calved from the eastern Ross Ice Shelf between Roosevelt Island and King Edward VII Land in Antarctica in October 1987.[1] The iceberg measured 154 kilometres (96 mi) long and 35 kilometres (22 mi) wide with a total area of 5,390 square kilometres (2,080 sq mi).[1] It is one of the longest icebergs ever recorded.[1] The calving took place immediately east of the calving site of Iceberg B-15 and carried away Little America V.[1]
Starting in October 1987, Iceberg B-9 drifted for 22 months and covered 2,000 kilometres (1,200 mi) on its journey.[1] Initially, B-9 moved northwest for seven months before being southward by a subsurface current that eventually led to its colliding with the Ross Ice Shelf in August 1988.[1] It then made a 100-kilometre (62 mi) radius gyre before continuing its northwest drift. B-9 moved at an average speed of 2.5 kilometres (1.6 mi) per day over the continental shelf, as measured by NOAA-10 and DMSP satellite positions, and the ARGOS data buoy positions.[1] In early August 1989, B-9 broke into three large pieces north of Cape Adare.(Wikipedia)PhotographerChris Rudge Last edited by: Jenny Ryan
