Aerial surveys have shown that what appeared to be one large island, Pitt, is actually a group of small islands. As they lie in one group with no logical division between them, the earlier name of Pitt was amended to Pitt Islands and extended to cover all the islands north of Renaud Island. The name Martin Islands was transferred to the group now described in order to preserve Charcot's name in the area. == See also == * List of antarctic and sub-antarctic islands
