The 14C reservoir age of the surface ocean was determined for two Holocene periods (4908-4955 and 3008-3066 calendar (cal) B.P.) using U/Th-dated corals from Biscayne National...本研究采用采自比斯坎国家公园（Biscayne National...）的铀钍（U/Th）定年珊瑚，测定了两个全新世（Holocene）时期（4908~4955与3008~3066日历纪年距今年份（cal B.P.））的表层海水14C储层年龄（14C reservoir age）。
