Formation of Antarctic Bottom Water in Cape Darnley

Caption

The mechanism by which Antarctic Bottom Water is formed as a result of high sea ice production off the coast of Cape Darnley, Antarctica. A large amount of sea ice is formed downstream of the iceberg tongue that extends out from the Antarctic Continent, creating an area of high ice production (polynya). This sea ice formation produces heavy water, which sinks to form the Antarctic Bottom Water (AABW).
