Site description Pearl Rocks lie several km offshore from the western coast of Tower Island, ~25 km from the Davis Coast of the Antarctic Peninsula. Pearl Rocks are uncharted, so the IBA has been defined as an elliptical area centered on the approximate position of the northernmost of the three highest islets in the Pearl Rocks group.

Information on the environment at Pearl Rocks is not available. The nearest permanent scientific stations are Gabriel de Castilla (Spain) and Decepción (Argentina), located ~80 km to the northwest at Port Foster, Deception Island. These summer-only stations have a combined capacity of 90 people.
