アラスカ沖のコアを用いて過去17,000年間の一次生産量(TOCやCdから)や栄養塩利用の程度(δ15N)の変化を議論。特にB/AとHolocene初期は表層での一次生産が高く、低層は低酸素の状態にあったらしい。またそれらは海水準の上昇に伴う微栄養塩(Fe)の流入量の上昇と関係があるらしい。
High-resolution sea surface reconstructions
off Cape Hatteras over the last 10 ka
Cléroux, C., M. Debret, E.
Cortijo, J.-C. Duplessy, F. Dewilde, J. Reijmer, and N. Massei
Cape Hatteras(大西洋中緯度域)における堆積物コアの浮遊性有孔虫(Globigerinoides ruberとPulleniatina
obliquiloculata)殻Mg/Caとδ18Oから過去10,000年間の水温・塩分を高時間解像度で復元。8.3kaと5.2-3.5kaに高塩分化。特に5.2-3.5kaの高塩分化は湾流の北上によって低塩分水の北からの流入が低下したことが原因として考えられる。MOCの弱化との関連?また特にHolocene初期に1000年周期が検出。総日射量(TSI:Total Solar Irradiance)と同じ位相?
※1 P. obliquiloculata is a warm water species whose bulk shell
geochemical composition indicates calcification at the base of the upper
thermocline, around 100 m depth [Cléroux et al., 2007; Farmer et al., 2007;
Steph et al., 2009]
※2 HoloceneのTSIの復元はアイスコア10Beに基づくらしい[Steinhilber et al., 2009, GRL]

モデル(中程度の複雑性の地球システムモデル:CLIMBER-2)で氷期-間氷期の炭素循環を再現。
(1)氷期に入る際の80ppmほどの大気中CO2濃度の低下
(2)氷期の大気中CO2濃度の低下(~80ppm低下)
(3)退氷期の急激な大気中CO2濃度の上昇(~50ppmv)
もうまく再現できているらしい。またモデルに組み込んでいる深層水のδ13Cもコアの復元結果と整合的。
