Tolong jelaskan mengenai Documentation dari Gunung es A-38

A-38 offered researchers an opportunity to observe the breaking up and decay of an iceberg, though the imagery was affected by heavy cloud cover in the region around South Georgia.  Because the iceberg was grounded (and therefore stationary) high-resolution imagery from the Advanced Spaceborne Thermal Emission and Reflection Radiometer satellite could be ordered to investigate it.  This allowed researchers to test models of melting and decay against a real-life example.
