-lll- AECD -3446 nd in the vicinity of the debris resulting from the blast consisted of two algae, dophora and Lyngbia. ; These algae are primitive in type and could be expected the first to reappear after the flora had been exterminated. Other more ad- : ced forms were not present in this area but were found in abundance at the islands not exposedto the effects of the blast. The algae were found in great bers at Bikini, Enyu, Amen, Erik, Namu, and Likiep Islands, even though number of different species was not great. - ‘The second phase was to collect all algae that were found. Lithothamnion sp. Following is a Bikini I,, Likiep (Lado) - on outer reef, forming part of the reef itself, giving the characteristic red color to the reef, Lithopyllum sp. Bikini I., AmenlI. - on outer reef, and also making up the reef. Avrainvillea sp. Bikini l., Enyu I. - found only in isolated spots attached to coral heads similar to ; Udotea. Scytonema Myochrous EnyulI,, AmenI., Runit I. - attached to rocks, found on LCT 816 at the water line, Padina sp. Amen I,, Eberiru-Aomon (dredge 40-60) - Hydroclathrus sp. attached to rocks and barge at varying depths. Amen I, only - attached to the bottom, sparse growth. Lyngbia semiplena AmenI,, Erik I., Eberiru~Aomon (dredge 40-60") - in fast-flowing water attached to rocks. Valonia sp. . - IgurinI., RigililI., Eberiru-Aomon dredge, Likiep I, (outside) - attached on the under side of rocks usually in low water. Dictyota sp. Rokar-Enyu dredge (60-100'), Eberiru I., Eberiru~Aomon dredge - attached to rocks at varying depths. UNIVERSE OY
