Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km 2 (5,500,000 sq mi).
A depiction of an Arctic marine food web. The phytoplankton, the base of the food web, are able to grow due to the polynya in the sea ice above them. In general, polynyas tend to be more biologically productive as a result of containing more phytoplankton than the surrounding water. [ 16 ]
The Antarctic continental shelf is a submerged piece of the Antarctic continent that underlies a portion of the Southern Ocean — the ocean which surrounds Antarctica. The shelf is generally narrow and unusually deep, its edge lying at depths averaging 500 meters (the global mean is around 100 meters), with troughs extending as far as 2000 ...
