1南海北部末次间冰期早期的突然降温事件显示文摘南海北部陆坡ODP1144站96.49-137.6 mcd 1)井段的高分辨率浮游有孔虫定量分析与δ18O测定表明末次间冰期(MIS 5.5即5 e)内发生过一次表层海水突然降温的事 件, 冬季水温下降幅度可达7.5℃, 表层水δ18O值也下降1.2‰. 此次降温事件在西欧和北大西洋均已发现, 相互可以对比, 但南海记录的降温事件更加强烈. 此次事件推测由中低纬地区而非极地冰盖引起; 由于黑潮标志种Pulleniatina obliquiloculata对此次降温事件反映最为强烈, 有可能与西太平洋低纬度地区的古海洋学变化有关. 此次事件可认为属“新仙女木期”式的降温, 表明末次间冰期气候的变异性.涂霞 郑范 王吉良 汪品先 蔡慧梅 C.Bühring M.Sarnthein 2001中国科学(D辑)2001,31,10:16
2An abrupt cooling event early in the last interglacial in the northern South China Sea显示文摘The high-resolution quantitative analysis of the planktonic foraminifera and the δ18O records of the section between 96.49-137.6 mcd at ODP Site 1144 on the continental slope ot northern South China Sea reveals an abrupt cooling event of sea surface temperature (SST) dur ing the last interglacial (MIS 5.5, i.e. 5e). The dropping range of the winter SST may come to 7.5℃corresponding to 1.2‰ of the δ18O value of sea surface water. This event is comparable with those discovered in the west Europe and the northern Atlantic Ocean, but expressed in a more intensive way. It is inferred that this event may have been induced by middle- to Iow-latitude processes rather than by polar ice sheet change. Since the Kuroshio-index species Pulleniatina obliquilocu lata displayed the most distinct change at the event, it may also be related to the paleocean ographic change of the Iow-latitude area in the western Pacific Ocean. This event can be consid ered as one of 'Younger Dryas-style coolings' and is indicative of climate variability of the last in terglacial stage.涂霞 郑范 王吉良 蔡慧梅 汪品先 C.Bühring M.Sarnthein 2001Science China Earth Sciences2001,44,10:7
