South American–Antarctic Ridge Sandwich Trench had begun. South American–Antarctic Ridge The South American–Antarctic Ridge (SAAR or AAR) is the tectonic spreading center between the South American Plate and the Antarctic Plate. It runs along the sea-floor from the Bouvet Triple Junction in the South Atlantic Ocean south-westward to a major transform fault boundary east of the South Sandwich Islands. Near the Bouvet Triple Junction the spreading half rate is , which is slow, and the SAAR has the rough topography characteristic of slow-spreading ridges. The boundary between the South American and Antarctic plates can be divided into three parts of which the SAAR
