Weddell Gyre
The
Weddell Gyre
is one of the two
gyres
that exist within the
Southern Ocean
. The gyre is located in the
Weddell Sea
, and rotates clockwise. The gyre is formed by interactions between the
Antarctic Circumpolar Current
and the
Antarctic Continental Shelf
. Due to the
Coriolis force
acting to the left in the
Southern Hemisphere
and the resulting
Ekman transport
away from the centres of the gyre, these regions are very productive due to upwelling of cold, nutrient rich water.
