To understand how hermatypic corals expanded/shrunk their geographical distribution ranges in response to the global climate changes during glacial-interglacial cycles, glacial coral reef deposits in Kikai Island of Ryukyu Islands, located near the northern limit of coral reefs, were collected by the shallow drillings. Lithologic and stratigraphic investigations of these reef deposits indicate that coral reefs were developed during the glacial low sea levels at 40-70 kyr B. P. and 140 kyr B. P. Further, taxonomic studies of fossil corals demonstrated that these glacial reefs were partly comprised of corals dominated in the modern temperate regions along the Japanese archipelago.

为了解冰期-间冰期全球气候变化对雌雄珊瑚地理分布范围的影响，采用浅层钻探法采集了位于琉球群岛Kikai岛珊瑚礁北部边界附近的冰川珊瑚礁沉积物。这些礁体的岩性和地层调查表明，这些礁体发育于40 ~ 70 kyr b.p.和140 kyr b.p.的冰川低海平面时期。化石珊瑚的分类研究表明，这些冰礁部分由珊瑚组成，主要分布在日本列岛一带的现代温带地区。
