☆Geophysical Research Letters☆

A 750 year ice core record of past biogenic emissions from Siberian boreal forests
Eichler, A., S. Brütsch, S. Olivier, T. Papina, and M. Schwikowski (2009), Geophys. Res. Lett., 36, L18813, doi:10.1029/2009GL038807.
→氷床コアで過去750年分のアンモニア、ギ酸を測定し、シベリアの森林からの放出を復元。最近60年間では人間活動も大きく影響しているらしい。

Precipitation over South America during the Last Glacial Maximum: An analysis of the “amount effect” with a water isotope-enabled general circulation model
Lee, J.-E., K. Johnson, and I. Fung (2009), Geophys. Res. Lett., 36, L19701, doi:10.1029/2009GL039265.
→ブラジルの鍾乳石d18Oを水同位体GCMで解析して、現在およびLGMでの降水d18Oを制御している要因を調べた。雨量効果の他に、蒸気のd18Oが変化することも重要らしい。

Metamorphism of stratified firn at Dome Fuji, Antarctica: A mechanism for local insolation modulation of gas transport conditions during bubble close off
Fujita, S., J. Okuyama, A. Hori, and T. Hondoh (2009), J. Geophys. Res., 114, F03023, doi:10.1029/2008JF001143.
→南極ドームFujiで採取された112.59mのfirnコアで、firnが固まるプロセスや泡形成のプロセスを研究して、ローカル日射量がO2/N2比に影響するメカニズムなどを調べた。


☆Paleoceanography☆

Diachronous benthic δ18O responses during late Pleistocene terminations
Lisiecki, L. E., and M. E. Raymo
Paleoceanography (2009) 24, PA3210, doi:10.1029/2009PA001732.
→底性有孔虫d18O に記録されたPleistoceneの退氷期の年代を、大西洋12カ所と太平洋9カ所で比較すると、太平洋は大西洋よりも数千年遅れていた。つまり酸素同位体カーブを用いた年代決定は、数千年の誤差を伴うので要注意。
