A-38 was a large iceberg that split from the Filchner-Ronne Ice Shelf in Antarctica in October 1998. Soon after formation it split into two pieces, A-38A and A-38B, which drifted westwards on the Weddell Gyre. The icebergs moved north along the Antarctic Peninsula and reached its tip in February 2003. A-38A and A-38B increased speed in open sea and grounded in shallower waters to the east of South Georgia Island in December 2003. A-38A broke up into three pieces in March 2004 and drifted north where it decayed. A-38B split into two in April, with the eastern portion, now known as A-38G, drifting north and west to decay. The remainder of A-38B remained grounded, interfering with the foraging routes of seals and penguins in South Georgia, resulting in the deaths of their young. On 20 August A38-B broke into two, with the new portion drifting north and breaking up. The remainder of A-38B continued to break up through September 2004 and had completely decayed by 2005. Calving Iceberg A-38 calved from the Filchner-Ronne Ice Shelf, Antarctica, in October 1998 from a position near to Berkner Island. The calving was caused by stresses imposed on the ice shelf by the Hemmen Ice Rise. The calving was witnessed over a period of decades as inlets in the shelf, which filled with sea ice, snow and small icebergs, gradually grew in size. Two of these inlets, one perpendicular to the front of the ice shelf and one parallel to it, met and led to the formation of A-38. At the point of calving the iceberg was by in size. It was first recognised on 13 October 1998 by United States National Ice Center scientist Mary Keller from imagery provided via the Defense Meteorological Satellite Program, though Glenn Grant and Jeff Otten of the United States Antarctic Program's Palmer Station claimed to have spotted the iceberg the same day. The iceberg carried with it Filchner Station, a German research post, manned only during the summer. The Germans hoped to land on the iceberg to recover equipment from the post during the southern summer of 1998–1999. At A-38 was the largest iceberg that had been observed in a decade, the previous largest being B-9 observed in October 1987. The calving was regarded by the National Oceanic and Atmospheric Administration as "a possible indicator of global warming". By 16 October it had moved a couple of
