北極海における熱力学効果は大気海洋相互作用に影響を与え,そこからの淡水流出は北大西洋の熱塩循環を変える可能性をもっているので,北極海の気候研究は需要である。観測データだけから熱・淡水収支を知るのは困難なので,海氷海洋モデルを大気データと河川からの淡水供給で駆動することによって,熱・淡水収支を調べた。モデルにはネプチューン効果とフラックス修正項が入っている。北極海への熱流入はフラム海峡からの46TW(T=10^<12>)が主である。バレンツ海には43TWが入るが,そのうちほとんどはバレンツ海で大気へ逃げ,北極海には2TWしか入らない。80,000km^3の北極海淡水は,ほぼカナダ海盆とユーラシア沿岸に溜まっている。淡水供給源は河川,降水,ベーリング海峡からの海水流入である。淡水流出は,海水としてカナダ多島海からの3,000km^3 yr^<-1>とフラム海峡からの1,000 km^3 yr^<-1>であり,海氷としてフラム海峡からの1,900 km^3 yr^<-1>である。

熱帯地域において,Brontispa longissima(Gestro)はヤシの木に重大な被害をもたらす害虫である。我々は,熱帯マングローブの潜在的殺虫剤リード化合物探索研究において,インドマングローブXylocarpus moluccensisの種子からΔ8,14二重結合をもつメキシカノライドであるカヤシンと2'S-メチルブタノイルプロセラノリドを単離した。これらの化合物の構造は文献データと比較して同定した。50μg/mlの濃度では,カヤシンはB. longissimaの2齢から5齢幼虫に対して強い殺虫効果を示し,2'S-メチルブタノイルプロセラノリドは5齢幼虫に対して顕著な殺虫効果を示した。B. longissimaの5齢幼虫に対する24時間と48時間暴露のLC50(半数致死濃度)は,カヤシンは7.27と3.39μg/ml,2'S-メチルブタノイルプロセラノリドは10.57と4.03μg/mlであった。2種の化合物のB. longissimaの5齢幼虫に対する殺虫活性は,アザジラクチンとトオセンダニンよりも強く,ロテノンと同程度であった。しかし,Prodenia litura(Fabricius)の3齢幼虫に対しては,これらの化合物は中程度の摂食阻害活性しか示さなかった。以上の結果は,カヤシンと2'S-メチルブタノイルプロセラノリドは,B. longissimaの幼虫に対して選択的な殺虫活性を持っていることを示唆しており,B. longissima防除用の有力な殺虫剤候補になると思われる。

The GEOTRACES Intermediate Data Product 2017 (IDP2017) is the second publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2016. The IDP2017 includes data from the Atlantic, Pacific, Arctic, Southern and Indian oceans, with about twice the data volume of the previous IDP2014. For the first time, the IDP2017 contains data for a large suite of biogeochemical parameters as well as aerosol and rain data characterising atmospheric trace element and isotope (TEI) sources. The TEI data in the IDP2017 are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons at crossover stations. The IDP2017 consists of two parts: (1) a compilation of digital data for more than 450 TEIs as well as standard hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing an on-line atlas that includes more than 590 section plots and 130 animated 3D scenes. The digital data are provided in several formats, including ASCII, Excel spreadsheet, netCDF, and Ocean Data View collection. Users can download the full data packages or make their own custom selections with a new on-line data extraction service. In addition to the actual data values, the IDP2017 also contains data quality flags and 1-σ data error values where available. Quality flags and error values are useful for data filtering and for statistical analysis. Metadata about data originators, analytical methods and original publications related to the data are linked in an easily accessible way. The eGEOTRACES Electronic Atlas is the visual representation of the IDP2017 as section plots and rotating 3D scenes. The basin-wide 3D scenes combine data from many cruises and provide quick overviews of large-scale tracer distributions. These 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessment of tracer plumes near ocean margins or along ridges. The IDP2017 is the result of a truly international effort involving 326 researchers from 25 countries. This publication provides the critical reference for unpublished data, as well as for studies that make use of a large cross-section of data from the IDP2017. This article is part of a special issue entitled: Conway GEOTRACES - edited by Tim M. Conway, Tristan Horner, Yves Plancherel, and Aridane G. González.

We employ first-principles density functional theory calculations to study the surface reconstruction, energetic stability, and electronic structure of diamond C(331) surface. Spontaneous formation of graphene-like stripes on the reconstructed surface is found to occur as the surface terrace C atoms transform from sp3 to sp2 hybridization upon structural relaxation. The comparison of the calculated absolute surface energies of C(331), C(111), and C(110) surfaces demonstrates the energetic stability of the graphitic-like C(331) surface. Local density of electronic states analysis reveals the occurrence of localized electronic states near the Fermi level, which may have a significant impact on the surface conductivity.
