Bird log data : Atlantis Two - cruise 8, International Indian Ocean Expedition

Abstract

Following the "Preliminary Guide to the Birds of the Indian Ocean" (Watson, Zusi & Stover, Smithsonian Institution, 1963} our Indian Ocean Bird Log begins at a position (20°N, 37°30'E) in the Red Sea off Port Sudan which we reached on the afternoon of l August, 1963. Thus the southern portion of the Red Sea and the Gulf of Aden are included in the area covered by our Indian Ocean records. The northern boundary line is the southern coast of Arabia, 20°N line to India and the west coast of India from Bombay to Ceylon. The furthest point East that we reached is Colombo (7°N 80°E) and the eastern boundary line runs from there through the Chagos Is. (6°S 71°E) to Mauritius (20°S 57°30'E) and the southern tip of Madagascar. The western boundary is the coast of Africa as far south as cape Delgardo (10°30'S 40°30'E) thence via the Comoros to Madagascar. We quit the region east of Lourenco Marques (26°S 37°E) around noon on the 11 November, 1963. About one third of the area of. the Indian Ocean falls within these bounds.
