♣Quaternary Science Reviews♣

1. Authigenic 10Be/9Be ratios and 10Be-fluxes (230Thxs-normalized) in central Baffin Bay sediments during the last glacial cycle: Paleoenvironmental implications

Quentin Simon, , , Nicolas Thouveny, Didier L. Bourlès, Laurence Nuttin, Claude Hillaire-Marcelb, Guillaume St-Onge

•10Be/9Be ratios and 10Be-fluxes yield equivalent results from glaciomarine sediments.

•10Be-systematic variability mainly obeys to glacio-climatic condition changes.

•10Be production proxies do not allow to characterize the geomagnetic features in PC16.

•Denudation rates are steady except for brief ice surging episodes coeval to H-events.

•10Be concentration is controlled by freshwater inputs from regional Ice Sheets.

♣Palaeogeography, Paleoclimatology, Paleoecology♣

2. Sedimentary responses to sea-level rise and Kuroshio Current intrusion since the Last Glacial Maximum: Grain size and clay mineral evidence from the northern South China Sea slope

Jianguo Liu, , , Rong Xiang, S.-J. Kao, Shaoying Fu, Liping Zhou

•Taiwan sediment contribution reached the peak (> 80%) in the Holocene.

•The Pearl River sediment contribution was the highest (< 30%) during the LGM.

•The KC might be significant force for Taiwanese sediment transport.

•Sediment sources remained stable as sea level rose to a certain height.

3. Lacustrine record of centennial- and millennial-scale rainfall variability of the East Asian summer monsoon during the last deglaciation: Multi-proxy evidence from Taiwan

Xiaodong Ding^a, Liwei Zheng^a, Dawei Li^a, Tien-Nan Yang^b, Teh-Quei Lee^b, Shuh-Ji Kao^a,

•The EASM variability during the last deglaciation was reconstructed based on high-resolution multi-proxy and well-dated lacustrine records from Taiwan.

•The detailed information of the millennial- and centennial-scale oscillations of the EASM were unraveled.

•The variation of SST in the tropical Pacific might have synergistic control on the EASM precipitation in Taiwan on centennial timescale during the last deglaciation.

•High sedimentation events during the early Holocene in our record probably related to frequent typhoon activities.

4. A new late Quaternary palaeohydrological record from the humid tropics of northeastern Australia

M.A. Burrows^{a, ,} , H. Heijnis^b, P. Gadd^b, S.G. Haberle

•High resolution X-ray Fluorescence (XRF) is presented as a robust palaeoclimatic proxy

•XRF identifies wet and dry shifts in a complex sedimentary sequence extracted from a volcanic crater in NE Australia

•XRF record correlates well with magnetic susceptibility, humification, grainsize, macrocharcoal, δ13C, C/N and pollen

•Coastal East Antarctica dust sources and pathways vary between climate periods.

•Our data are consistent with a rapid retreat of Ross Ice Shelf that caused shift in storm trajectories to Taylor Dome.

•Ice shelf extent affects regional climate agreeable with dust variations in the record of Taylor Dome.

7. Late Miocene–Pliocene Asian monsoon intensification linked to Antarctic ice-sheet growth

Hong Ao^{a, ,} , Andrew P. Roberts^b, Mark J. Dekkers^c, Xiaodong Liu^a, Eelco J. Rohling^{b, d}, Zhengguo Shi^a, Zhisheng An^a, Xiang Zhao

•Improved magnetochronology for the Shilou Red Clay on the Chinese Loess Plateau.

•New magnetic records of the Late Miocene–Pliocene East Asian Summer monsoon.

Matt McCarthy教授の来訪

こんにちは．D3の石輪です．

4月の上旬にIsoEcol 2016というworkshopが本郷で開催され，横山研からも発表がありました．
http://isoecol.com/2016/

workshop期間中の中日を利用して，Matt McCarthy教授が来訪されました．

カリフォルニア大学サンタクルーズ校に所属しているMatt McCarthy教授は，有機地球化学を使った生物地球化学が専門で特定有機化合物の同位体分析の第一人者です．

加速器をはじめとして実験室の見学をして頂き，加速器についてとても羨ましがったそうです．
