Scotia Sea
The islands do have vegetation.  They have been called Scotia Sea Islands tundra ecoregion.  These include South Georgia, the volcanic South Sandwich Islands and the South Orkneys in the Scotia Sea as well as the remote South Shetland Islands near the Antarctic Peninsula and the small isolated volcano Bouvet Island. All these islands are in the cold seas below the Antarctic convergence. These areas have tundra vegetation of mosses, lichen and algae. Seabirds, penguins and seals feed in the surrounding waters.
