Research Abstract

本研究の目的は,光ルミネッセンス年代測定法(以下OSL)を,炭酸塩に乏しい極域寒冷圏の海底堆積物コアに適用し,広域に対比可能な年代層序を行い,時間分可能の高い古海洋変動を明らかにすることである。今年度は,以下の点を実施した.(1)光ルミネッセンス装置の立ち上げ・測定精度確保のための,基礎実験を徹底して行い,の後,本格的に,海底堆積物の光ルミネッセンス測定を行った.取り扱う試料は,オホーツク海(MR06-04航海,YK07-12航海),ベーリング海(MR06-04航海)からの海底堆積物コア試料である.(2)光ルミネッセンス測定と同じ層準の試料について,自然放射線年間線量を測定するため,自然放射線年間線量測定のためのGe検出器を調整・設置(名古屋大学より)を行って,自然放射線年間線量実験室の立ち上げを行い,実測定を開始した.(3)坂本,池原,岡田,高橋は,統合深海掘削計画代323次航海(ベーリング海)に乗船し,光ルミネッセンス,酸素・炭素同位体比,非破壊コア解析ほかのための試料を採取し,分析を開始した.(4)古海洋プロクシの分析の継続:上記試料について,古海洋プロクシの分析を行っている.(a)有孔虫の酸素・炭素同位体比測定(坂井).(b)U-channelサンプルを使った,非破壊透過X線コアロガー,非破壊蛍光X線コアロガー,非破壊分光コアロガーによる連続分光スペクトル測定(飯島),(c)古地磁気測定(岡田ほか),(d)陸上起源粒子の粒度分析,漂流岩屑解析(坂本),(e)珪藻化石の内,海氷指標種の群集解析(高橋ほか),(f)無機元素,特にBa量(坂本他),(g)有機化合物組成(池原ほか).(5)光ルミネッセンス測定を本格的に行うため,ポスドク研究員を1名公募の上,雇用した.(6)関連する研究成果の発表を行った
