IMAGE OF THE MARINER GLACIER on the Borchgrevink Coast of Victoria Land reveals numerous flows of ice from the Trans Antarctic Mountains. They form several elongated glacier tongues that spill out onto the sea ice covering the Ross Sea. These tongues will eventually fracture along the crevasses and drift free as icebergs.




ENORMOUS ICEBERG, 15 miles (25 kilometers) long, begins its sea journey as it breaks free from the Polar Record Glacier on the Ingrid Christensen Coast. The surrounding sea is dotted with smaller icebergs.
