From 0900 on 17 June to 0615 on 19 June 1965 Caroline Atoll was visited by a field party from the Pacific Ocean Biological Survey Program (POBSP) of the Smithsonian Institution. The field party, led by Sibley, collected and made observations on vascular plants, fish, reptiles, mammals, and birds. All islands with the exception of the northern two-thirds of Nake were visited. Prior knowledge of the biota of Caroline Atoll is very scant, deriving almost entirely from the visits of F. D. Bennett in 1835, Devoy in 1875, and the U.S.S. Hartford in 1883.
