Antarctic Convergence

The Antarctic Convergence (pronunciation: /ænˈtɑːrktɪk kənˈvɜːrdʒəns/), also known as the Polar Front, is a natural boundary that separates the cold Antarctic waters from the warmer waters of the Subantarctic.

Etymology

The term "Antarctic Convergence" is derived from its geographical location, converging towards the Antarctic region. The term "Polar Front" is used synonymously due to its position at the forefront of the polar region.

Description

The Antarctic Convergence is characterized by a sharp change in temperature, where the cold, northward-flowing Antarctic waters meet the warmer, southward-flowing subantarctic waters. This results in a zone of upwelling nutrients, which supports a high level of marine biodiversity, including various species of krill, squid, seals, and birds.
