南极布兰斯菲尔德海峡PC10岩心代表了112.5 ka B.P.以来的沉积记录。通过硅藻、氧同位素和磁组构参数的定量分析,表明沉积记录对气候变化的反应十分敏感。岩心包含了氧同位素1～5期,古气候演变史大致可分为12个带:末次间冰期的暖高峰期(112.5～106.4 kaB.P.)、第一冷期(106.4～101 ka B.P.)、第一暖期(101～92 ka.B.P.)、第二冷期(92～84 ka.B.P.)和第二暖期(84～75 ka B.P.),末次冰期的早冰期(75～59 ka B.P.)、间冰期(59～24 ka B.P.)、晚冰期(24～14 ka B.P.)、波林-阿洛德(Bolling-Allerod)暖期(14～12 ka B.P.)和新仙女木(Younger Dryas)冰期(12～10 ka B.P.),冰后期的温暖期(10～2.4 ka B.P.)和2320 a B.P.左右的寒冷气候事件。该12个古气候带与全球晚更新世以来的气候变化情况基本一致。
PC10 cores from Bransfield Strait, Antarctica, represent sedimentary records since 112.5 ka B.P. Through the quantitative analysis of diatoms, oxygen isotopes and magnetic structure parameters, sedimentary records are very sensitive to the climate change. The core contains 1 ~ 5 oxygen isotopes. The paleoclimate evolution history can be divided into 12 zones: the warm peak in the last interglacial (112.5 ~ 106.4 kaB.P.), the first cold period (106.4 ~ 101 ka BP) , The first warm period (101-92 ka.BP), the second cold period (92-84 ka.BP) and the second warm period (84-75 ka BP), the last glacial (75-59 ka BP (59 ~ 24 ka BP), late glacial (24 ~ 14 ka BP), Bolling-Allerod warming (14 ~ 12 ka BP) and Younger Dryas Glacial (12 ~ 10 ka BP), warm period of late ice (10 ~ 2.4 ka BP) and cold weather of 2320 a BP. The 12 ancient climatic zones are basically the same as the climate change since the late Pleistocene.
