Scotia Arc is the island arc system forming the north, east and south border of Scotia Sea. The arc comprises submarine ridges and the island groups of South Orkneys, South Sandwich Islands, Clerke Rocks, South Georgia, Shag Rocks, Isla de los Estados, and Burdwood Bank linking the mountains of Antarctic Peninsula to those of Tierra del Fuego (specifically the Mitre Peninsula) and the Andes.[1]

The arc is related to the subduction of the South American Plate to its east under the South Sandwich Plate.
