Weddell Gyre

South of the ACC and spreading northeast from the Antarctic Peninsula, the gyre is an extended large cyclone.

Axis of the gyre is over the southern flanks of the South Scotia, America-Antarctic, and Southwest Indian Ridges.

[4] In the northern part of the gyre, shelf water influence is traced continuously at 22°E from the top of the Antarctic Peninsula.

In the Weddell Sea Deep Water, there is a 2 gyre cyclonic system inferred and is able to spill over the South Scotia Ridge.

[5] The intensity of the boundary currents are controlled by the seasonal fluctuations, but the time-scale, days to weeks dominates the interior.
