The expedition made a topographical survey of the coral reefs, an ecological survey of the corals on it and a study on the metabolism of the reef. A reference collection of samples of the flora and fauna of the area was also undertaken. Small, rocky, Resurgent Island emerged after the naming of the Three Brothers and was named after the RFA Resurgent which supported the 1975 Danger Island scientific research expedition to the area.
