Douglas MacAyeal, a National Science Foundation-funded researcher from the University of Chicago, uploads new instructions to an automated weather station on iceberg B-15A. MacAyeal landed on the immense iceberg, perhaps for the last time, in January 2005 to service weather stations he had placed on the iceberg a year ago.
