Deep Pacific ventilation ages during the last deglaciation: Evaluating the influence of diffusive mixing and source region reservoir age
David C. Lund
　氷期から間氷期にかけての大気中CO2濃度上昇には深層水の換気（ventilation）が重要であったと考えられているが、太平洋深層水の記録からそれを支持する証拠はほとんど得られていない。その一つの原因は深層水の年齢の推定法にあるかもしれない。
　従来のprojection age法から、トレーサーの拡散を考慮したtransit-time equilibration-time distribution（DeVries & Primeau, 2010）法に変えて計算をやり直した。結果はそれほど大きくは変わらず、HS1に1,000年、YDに500年古い深層水の年齢となった。これは南大洋において換気が活発化した（深層水の年齢は若くなるはず）という事実と相反するものである。表層水のリザーバー年代の変化によって見かけ上の深層水の年代が変化している？（浮遊性有孔虫14Cで年代モデルが作られているため）

ユーザートレーニング＠ドイツ

こんにちは、D1の関です。

9月初旬に4日間、ドイツに行ってきました！！
今回の主な目的は、大気海洋研究所のICP-MS (ELEMENT XR)が作られた本拠地で、ユーザートレーニングを受けることです。

でもまずは、今年の6月からドイツのGEOMAR(ゲオマール海洋研究所)で働いているChristelleに会って来ました！！
Christelleは今年の4月まで約2年半横山研にいて、私はとってもお世話になったので、感動の再会・・・！

ご飯食べながらお互いの近況や横山研の近況など、ゆっくり話ができました。
（もちろん、ICP-MSの現状の報告と話し合いも忘れずに！）
Christelleから、みなさんによろしく、だそうです(^^)

Christelleが働いている、GEOMARの建物。
すぐ横が海(汽水のフィヨルド)でした！

後半は、いよいよ、ICP-MS (ELEMENT XR)のユーザートレーニングです。
行くまではちゃんと話せるのか、困ってることが解決するのか不安でいっぱいでしたが、終わってみればたくさんのアドバイスをもらうことができました！

事前に質問リストを送った時には、
「たくさんありすぎて時間が足りないよ」
と言われていたものの、時間いっぱい対応してもらい、なんと全て解決することができました！
多くの人が5時には帰る中、遅くまで対応してくださった方々に感謝です！！


これからは教わったことを大気海洋研究所のICP-MS (ELEMENT XR)で実践して行きます。
たくさん学んだ分、やることがたくさんですが、本格的に分析ができる日を目指して、がんばって行こうと思います。

ユーザートレーニングを受けた建物。
日本とは何か雰囲気が違う・・・。

Bremenでの主な移動は、このバス(トラム)でした。
時間に正確で、本数も多くてとっても便利！！

高校連携講座＠熊本

こんにちは、くまモンです！

さて、ブログ書くかな…

…

9/18•19の2日間、東京大学大気海洋研究所の高校連携講座として熊本県内の高校（東稜高校・済々黌高校）に対して授業を行いました．

1日目は各高校で講義を行い、2日目は実際にフィールドワークを体験するため、人吉層の観察に加え、球泉洞と球磨川で採水を行いました．

講義風景

人吉層で説明をする横山先生

6.Recent global-warming hiatus tied to equatorial Pacific surface cooling
Yu Kosaka & Shang-Ping Xie
Nature 501, 403–407 (19 September 2013) doi:10.1038/nature12534

Despite the continued increase in atmospheric greenhouse gas concentrations, the annual mean global temperature has not risen in the twenty-first century. Using radiative forcing and SST in tropical Pacific as inputs of the climate model, they concluded that the hiatus in global warming is part of natural climate variability, tied specifically to a La-Nina-like decadal cooling. Although, similar decadal hiatus events may occur in the future, the multi-decadal warming trend is very likely to continue with greenhouse gas increase.

7.Rapid cross-density ocean mixing at mid-depths in the Drake Passage measured by tracer release
Andrew J. Watson, James R. Ledwell, Marie-José Messias, Brian A. King, Neill Mackay, Michael P. Meredith, Benjamin Mills & Alberto C. Naveira Garabato
Nature 501, 408–411 (19 September 2013) doi:10.1038/nature12432

Diapycnal mixing of mid-depth(~1.500 meters) waters undergoes a sustained 20-fold increase as the Antarctic Circumpolar Current flows through the Drake Passage. The great majority of the diapycnal flux is the result of interaction with restricted regions of rough ocean-floor topography.

◉PNAS
11.Origin and provenance of spherules and magnetic grains at the Younger Dryas boundary
Yingzhe Wu, Mukul Sharma, Malcolm A. LeCompte, Mark N. Demitroff, and Joshua D. Landis
PNAS 2013 110 (38) E3557-E3566; published ahead of print September 5, 2013, doi:10.1073/pnas.1304059110

They analyzed bulk sediment and magnetic grains / microspherules collected from the Younger Dryas boundary. The Os ratios of the spherules and their leachates shows that the spherules are likely terrestrially derived. The rare earth element patterns and Sr and Nd isotopes of the spherules indicate that their source lies in 1.5Ga Quebecia terrain in the northeastern North America.

12.Sea surface height evidence for long-term warming effects of tropical cyclones on the ocean

耳石薄片作成〜二次・三次切断〜

こんにちは、本郷キャンパス正門前の豚汁専門店の豚汁定食（680円）です！

間違えました、D2窪田でした。

今日も引き続き、本郷の岩石薄片室にて雨宮雨川くんとともに、薄片の二次〜三次切断を行いました。

スライドガラスに貼付けた耳石を二次切断し、1mm厚くらいまで薄くします

その後プレパラップという機械を使って三次切断。
写真左の回転刃を使ってさらに薄くします（~400μm厚くらい）

雨川くんが頑張ってくれたおかげで、あらかたの作成行程は終了し、あとは研磨剤でひたすら磨き上げる行程に入ります。

明日は僕のわがままを聞いてもらい、柏キャンパスに場所を移してのサッカー作業となります。

耳石薄片作成〜一次切断、スライドガラス作成〜

今日は雨宮雨川くんとともに、本郷キャンパスの岩石薄片作成室で作業しました。

岩石薄片作成室。な、懐かしすぎる…

今回の作業内容は、

１、樹脂埋めした耳石の一次切断

２、切断面を研磨

３、スライドガラスに接着剤で貼付け

の３つです。

切って

接着剤を塗って

できあがりっ！

前回同様、乾燥だったり乾固に時間がかかります。

一晩乾燥させ、明日からはいよいよ薄片作成の佳境、二次・三次切断〜研磨作業です。

明日も安全第一・食欲第二くらいで頑張ります。

今日のランチは雨川くんオススメの定食屋さんで「なめろうフライ」と「イナダの塩焼き」をいただきました。明日は豚汁定食っ！！

耳石薄片の断面。うっすらと縞が見えるの分かります？？

今回扱っているナマズの耳石ですが、僕らは「河川〜海へのナマズの移動」と「海の環境記録」が成長線方向に沿った同位体や微量元素の高精度分析から復元できることを期待しています。

Daniela I.V. Domeisen, Lantao Sun and Gang Chen

Accepted manuscript online: 9 SEP 2013 02:08PM EST | DOI: 10.1002/grl.50943

Key Points

Planetary-scale waves are crucial for stratosphere - troposphere coupling.

A synoptic - eddy feedback is needed to get the observed response.

The annular mode response is different for planetary- and synoptic-scale waves.

3. Projections of global changes in precipitation extremes from CMIP5 models

Andrea Toreti, Philippe Naveau, Matteo Zampieri, Anne Schindler, Enrico Scoccimarro, Elena Xoplaki, Henk A. Dijkstra, Silvio Gualdi and Jürg Luterbacher

Accepted manuscript online: 9 SEP 2013 02:23PM EST | DOI: 10.1002/grl.50940

Robin Chadwick and Peter Good

Accepted manuscript online: 9 SEP 2013 03:48PM EST | DOI: 10.1002/grl.50932

Key Points

There are large non-linearities in tropical rainfall pattern change

This has implications for the use of pattern-scaling

The non-linearities are due to the interaction of different processes

7. El Nino, the 2006 Indonesian Peat Fires, and the distribution of atmospheric methane

John Worden, Zhe Jiang, Dylan B. A. Jones, Matthew Alvarado, Kevin Bowman, Christian Frankenberg, Eric A. Kort, Susan S. Kulawik, Meemong Lee, Junjie Liu, Vivienne Payne, Kevin Wecht and Helen Worden

Accepted manuscript online: 9 SEP 2013 04:50PM EST | DOI: 10.1002/grl.50937

Key Points

1)El Nino can increase Methane Emissions From Tropical Fires

2)Indonesian Fire Emissions of Methane Estimated Using Satellite Data

8. Stationarity of the tropical pacific teleconnection to North America in CMIP5/PMIP3 model simulations

Sloan Coats, Jason E. Smerdon, Benjamin I. Cook and Richard Seager

Accepted manuscript online: 9 SEP 2013 09:06PM EST | DOI: 10.1002/grl.50938

Key Points

The ENSO-North American hydroclimate teleconnection is non-stationary in models

Teleconnection non-stationarity is linked to the strength of and changes in ENSO

The assumption of teleconnection stationarity is potentially unwarranted

9. Paleogeographic controls on the onset of the Antarctic Circumpolar Current

Daniel J. Hill, Alan M. Haywood, Paul J. Valdes, Jane E. Francis, Daniel J. Lunt, Bridget S. Wade and Vanessa C. Bowman

Accepted manuscript online: 10 SEP 2013 09:21AM EST | DOI: 10.1002/grl.50941

Accepted manuscript online: 11 SEP 2013 10:09AM EST | DOI: 10.1002/grl.50930

Key Points

Recent interannual variability of the AMOC dominated by mid-ocean anomalies

Most of this variability can be simulated as a response to atmospheric forcings

Model-data agreement improved when AMOC calculated using observational method

11. Permeable coral reef sediment dissolution driven by elevated pCO2 and porewater advection

T. Cyronak, I. R. Santos and B. D. Eyre

Accepted manuscript online: 11 SEP 2013 04:14PM EST | DOI: 10.1002/grl.50948

CaCO3 sediment dissolution under OA is important on an ecosystem scale

Other drivers of CaCO3 sediment dissolution need to be elucidated

12. Multi-model seasonal forecasting of global drought onset

Xing Yuan and Eric F. Wood

Accepted manuscript online: 12 SEP 2013 07:50AM EST | DOI: 10.1002/grl.50949

Key Points

Less than 30% of the global drought onsets can be detected by climate models

Missed drought events are associated with weak ENSO signal

Reliability is very important for a skillful probabilistic drought forecast

13. Extratropical forcing of El Niño/Southern Oscillation asymmetry

Bruce T. Anderson, Jason C. Furtado, Kim M. Cobb and Emanuele DiLorenzo

Accepted manuscript online: 12 SEP 2013 10:52AM EST | DOI: 10.1002/grl.50951

Key Points

Extratropical SLP changes impact the longitudinal structure of ENSO events

These impacts are found in observations and coupled-climate model simulations

SLP-induced ENSO asymmetries result in appreciable teleconnection differences

14. Contribution of the pacific decadal oscillation to global mean sea level trends

B.D. Hamlington, R.R. Leben, M.W. Strassburg, R.S. Nerem and K.-Y. Kim

Accepted manuscript online: 12 SEP 2013 11:28AM EST | DOI: 10.1002/grl.50950

Key Points

20. Quantifying errors in coral-based ENSO estimates: Towards improved forward modeling of δ18O

S. Stevenson, H. V. McGregor, S. J. Phipps and Baylor Fox-Kemper

Accepted manuscript online: 9 SEP 2013 09:20PM EST | DOI: 10.1002/palo.20059

Key Points

Observational uncertainties in coral isotope measurements are manageable

Linear SST/SSS to delta 18O conversions yield inaccurate ENSO amplitudes

Climate/delta 18O conversions can be improved by including seasonal influences

21. High epibenthic foraminiferal δ13C in the recent deep arctic ocean: implications for ventilation and brine release during stadials

Andreas Mackensen

Accepted manuscript online: 9 SEP 2013 09:35PM EST | DOI: 10.1002/palo.20058

Key Points

Strong 13C-Suess effect lowers δ13C of Arctic surface waters

Reduced stadial ABW δ13C suggested - due to diminished brine formation

Stadial benthic δ13C spikes in Nordic seas may reflect less Arctic brine
