In 1972–73 there was an underwater expedition to the Egmont Islands by the Joint Services (JSEI). Led by Sqn Leader “Dickie” Bird RAF, it was the first expedition of its kind in the Chagos. Cdr Alan Baldwin RN was the Deputy Leader and the scientific work was carried out under the direction of Dr David Bellamy. Its aim was to study coral reef formation and growth, as well as the islands' flora and fauna. The expedition members were taken from Gan, Addu Atoll by RFA Gold Ranger to Egmont Atoll and after their survey was completed they were brought back to Gan by RFA Stromness. Following its success, a second expedition was undertaken to Danger Island the following year.
