IODPプロポーザル審査委員会

横山准教授は、IODPのプロポーザル審査委員会 (SEP)に参加するため、カリフォルニア大学サンディエゴ校・スクリップス海洋研究所に正月早々に訪れていました。


会場は海のすぐ真横にある大学の会議場だったそうです。


現地の気温は毎日15℃くらいと、とても穏やかな気候だったそうです。


一方で同時期の東海岸は、マイナス40℃などの猛烈な寒波により空港閉鎖などが相次ぎ、5名強の委員はたどり着けず、オンラインでの音声での参加となる異常事態だったとか!




朝から夕方までみっちりと会議三昧の毎日だったそうです…お疲れさまでした。

Climate of the Past
Biogeochemical variability during the past 3.6 million years recorded by FTIR spectroscopy in the sediment record of Lake El'gygytgyn, Far East Russian Arctic
C. Meyer-Jacob, H. Vogel, A. C. Gebhardt, V. Wennrich, M. Melles, and P. Rosén
doi:10.5194/cp-10-209-2014
    Developed calibration models based on Fourier transform infrared spectroscopy (FTIRS) for the quantitative determination of biogenic silica (BSi), total organic carbon (TOC), and total inorganic carbon (TIC) in a 318 m-long sediment record with a basal age of 3.6 million years from Lake El'gygytgyn, Far East Russian Arctic.
    High accumulation rates of BSi indicate a productivity maximum during the middle Pliocene (3.6–3.3 Ma), followed by gradually decreasing rates during the late Pliocene and Quaternary. The average BSi accumulation during the middle Pliocene was ~3 times higher than maximum accumulation rates during the past 1.5 million years. The indicated progressive deterioration of environmental and climatic conditions in the Siberian Arctic starting at ca. 3.3 Ma is consistent with the first occurrence of glacial periods and the finally complete establishment of glacial–interglacial cycles during the Quaternary.
