In January, 2004, astronauts on board the International Space Station took this detailed picture of melt water pooled on the surface of iceberg A-39D, a 2-kilometer wide, 11-kilometer long iceberg and drifting near South Georgia Island. The different intensities of blue are interpreted as different water depths. From the orientation of the iceberg, the deepest water (darkest blue) lies at the westernmost end of the iceberg. The water pools have formed from snowmelt—late January is the peak of summer in the Southern Hemisphere.
