5. Ohno M., T. Hayashi, M. Sato, Y. Kuwahara, A. Mizuta, I. Kita, T. Sato, A. Kano, Millennial-Scale Interaction between Ice Sheets and Ocean Circulation during Marine Isotope Stage 100, Front. Earth Sci., 10.3389/feart.2016.00055, 2016.05, [URL], 約275万年前に北半球に大陸氷床が出現して以来、氷床の発達・衰退とそれに関連した熱塩循環の変化は、地球規模の気候変動において重要な役割を果たしてきました。しかし、初期の氷河期については、氷床の発達と海洋循環の間のつながりがいる確立は良く解っていません。本論文では、北極圏亜寒帯のガーダードリフトの深海堆積物から得た、海洋同位体ステージ100の新しい高解像度記録を示します。種々の指標の分析結果は、海洋同位体ステージ100における、千年スケールの氷山流出が北極大西洋の海面状態と深層流の変動に与える影響を明らかにしました。我々は、海水面温度の低下と北大西洋深層水成分の減少を伴う、氷山起源の岩屑イベントを8つ特定しました。これらの減少は、最後河期と同様に、氷山の流出に関連した深層水形成の弱体化によって解釈されます。 MIS 100の初期の氷山起源の岩屑イベントに含まれるドロマイト成分は、最終氷期のハインリッヒイベントと同様に、北米のローレンタイド氷床の大規模な崩壊を示唆しています。一方で、初期の氷河期の記録は、氷床と海洋の間の相互作用における1470年の周期性の欠如や、氷山起源岩屑の帯の北方へのシフトなど、最後氷期との違いも示唆しています。本論文で得られた高解像度データは、北半球大陸氷床発達初期の氷河期における千年単位の時間スケールでの氷床/海洋相互作用の理解を大きく前進させると考えられます。.
