摘要
本研究分析位於沖繩海槽北段海洋岩心CSH-2(31°13.73’ N,128°43.37’ E,水深703公尺,岩心全長737公分)之浮游有孔蟲Globigerinoides ruber與Globigerinoides sacculifer殼體之氧同位素組成、浮游有孔蟲化石群相對含量及14C年代,以建立沖繩海槽北段22 ~6 ka之間的古海洋紀錄。浮游有孔蟲氧同位素組成大致呈現冰期重、間冰期輕的趨勢(△δgl-intergl. = 3.00‰),並與 古海表溫度變化(△SSTgl-intergl. = 4.2℃)趨勢大致平行。岩心經14C定年結果,求其沉積速率顯示經過三階段變化,第一階段(22.3~13.0 ka)沉積速率60~74公分/千年;第二階段(13.0~12.9 ka)233公分/千年;第三階段(12.9~6.2 ka)12~21公分/千年。岩心中浮游有孔蟲化石可分為兩個不同群集:22-14 ka 為低溫低鹽沿岸流-西北太平洋溫帶水混合群集;14-6 ka 為高溫高鹽的黑潮化石群組合。配合殼體大小範圍在250~300μm的浮游有孔蟲組合、沉積速率、碳酸鈣含量、 SST及陸源物質含量等資料,可以綜合瞭解沖繩海槽北段22-6 Ka 古海洋環境歷史:22-14 ka(IS 1 event 以前):全球古海水面下降120 公尺情況下,大部分東海陸棚出露,岩心CSH-2位於(長江-)黃河水下扇附近環境,沉積速率大,稀釋了沉積物中碳酸鈣含量及浮游有孔蟲化石含量,大量陸源物質沉積則增加了陸源有機碳及營養鹽含量,使得浮游有孔蟲Neogloboquadrina dutertrei 含量高,此時沖繩海槽北段混合了低溫、低鹽、高營養鹽的中國大陸沿岸流及西北太平洋溫帶水團(Globorotalia inflata 及Globorotalia crassaformis為代表); 14-12.9 ka (Allöid)時,為短暫過渡變化時期,此時(長江-)黃河水下扇發展到極盛,同時海水面也開始上昇,東海陸棚逐漸為海水入侵,沖繩海槽北段已為高溫高鹽黑潮(Pulleniatina obliquiloculata與 Globigerinoides sacculifer為代表)入侵,但每克沉積物中浮游有孔蟲含量及破片含量達到最高值,顯示在此古海洋環境變化過渡時期沖繩海槽北段的水文極不穩定,或許有濁流沉積導致有淘選及化石破壞/溶蝕現象;12.9-6 ka (Younger Dryas 以來)海水面急遽上昇,(長江-)黃河水下扇快速向西側陸地方向後退,黑潮入侵沖繩海槽北段極為明顯,同時由於沉積速率極快速下降,使TOM、碳酸鈣含量及有孔蟲個數/公克相對增加。
