Iceberg Coastline

MBARI researcher Rob Sherlock took this photograph of a very large iceberg in the Weddell Sea (designated A-52), which was about 5 kilometers (3 miles) wide and 21 kilometers (12 miles) long. Because of rising temperatures, an increasing number of icebergs have been breaking off from Antarctic glaciers and ice sheets to drift around the Southern Ocean. In December 2005, Sherlock and several other MBARI biologists joined an expedition headed by biologist Ken Smith to study how these drifting icebergs affect the distribution of marine animals and algae in Antarctic waters.
