Tolong jelaskan mengenai A-38A at  measuring  by dari Gunung es A-38

A-38A and A-38B increased speed during their drift in open sea and both icebergs approached South Georgia Island, some  north of their initial position, in December 2003.  Both icebergs grounded in shallow seas some distance to the east of the island.  On 15 March 2004, A-38A broke into three pieces and began to drift northwards once more.  After a few weeks their progress could no longer be monitored by medium-resolution satellite imagery. In January 2004, another fragment of A-38, A-38D, which was covered in meltwater ponds, had drifted past South Georgia.

A-38B remained grounded  off South Georgia and on 12 April 2004 was measured at  in length.  It had broken into two portions, almost equal in size, by 15 April 2004.   The western portion remained known as A-38B while the eastern portion was named A-38G. From 17 to 18 April, A-38G drifted north and then west, decaying below satellite imagery detection capability within a few weeks.  Iceberg A-38B remained grounded for some months, affecting the foraging routes of adult seals and penguins, resulting in the death of young penguins and seals on the beaches of South Georgia.  A-38B broke into two along an existing crackline on 20 August 2004.  The new iceberg fragment drifted northwards and broke up.  A-38B continued to break up through August and September 2004 and had disappeared by 2005.
