    Daily precipitation samples for stable isotope analysis
    were collected throughout 2003 at Dome Fuji Station,
    inland East Antarctica. Stable isotopes show significantly
    depleted values with a large seasonal variability, which have
    never been obtained. Temporal changes in d-T relation and
    d-excess are consistent with those found in geographical
    distribution. Precipitation was obtained almost everyday,
    though the amounts were quite small (27.6 mm water
    equivalent (w.e.) annual total and 0.08 mm w.e. daily
    average). Half of the annual precipitation was accumulated
    by only 11 events (18 days) without seasonality. Since the
    precipitation events occurred under warmer circumstances,
    the precipitation-weighted temperature, which should be
    related directly to the isotopes, was significantly warmer
    than the mean annual surface temperature, which has
    usually been adopted as isotopic thermometer. This study
    provides significant information to understand present-day
    seasonality of precipitation and its isotopic composition in
    inland Antarctica.

    We studied diurnal and daily variations in triple oxygen isotopes in the euphotic zone of the Sagami Bay during
    summer 2003 and 2004. There were sharp changes in physical processes, driven by changes in wind speeds, during
    the study period. Mixed-layer 17D anomalies were negatively correlated with wind speeds, whereas dissolved
    oxygen (DO) and chlorophyll a (Chl a) were positively correlated, suggesting that both physical and biological
    processes influence the 17D anomaly. Vertical mixing affected estimation of gross oxygen production (GOP) in the
    mixed layer, whereas horizontal advection was negligible in the Sagami Bay during the study period. Hourly GOP
    estimates are consistent with fast repetition rate fluorometer (FRRF) measurements; relatively higher estimates
    from the former method were due to the storing of past productivity signal. Daily integrated production estimated
    from 17D anomaly and FRRF were consistent during the entire study period, whereas the estimation from a 18O
    spike incubation technique showed good agreement with the other two techniques only when the water mass
    structure was unchanged in the mixed layer.

    本研究では、光吸収強度の高い中赤外領域と光共振器で感度を飛躍的に向上させたレーザー光吸収分光法を用いて、存在比の極めて低い多重置換同位体分子の光吸収量を測定して同位体分子の存在比を直接分析する手法を開発する。二酸化炭素を第一の目標として、存在比がppmレベルの多重置換同位体CO2分子を、少量試料で高精度に分析できる手法の開発を目指す。本手法により、微量試料測定・連続モニタリング・その場分析などが可能となり、原子力工学のみならず、エネルギー工学、薬学、地球惑星科学、歴史学などへの展開も考えられ、多重置換同位体分子の超高感度分析を基盤とした新たな学術の創生につながると期待できる。
    1. 中赤外キャビティーリングダウン吸収分光法の開発
    環境試料などへの応用を想定し、試料量が微量な同位体分子に対するキャビティーリングダウン分光(CRDS)を可能とするために、分光ガスセルを設計し、その主要構成部品を整備した。後述の試料導入法を想定した設計としたものの、圧力制御系に必要な物品の選定に時間を要したため、ガスセルの構築したが、その特性評価にはいたらなかった。また、CRDSにてclumped isotopeの存在比を高精度測定するために、HITRANデータベースを用いて吸収線の計算を行い、妨害吸収線の影響や吸収強度、また、レーザー波長可変領域などを考慮して、最適と思われる波長帯を選択した。これらの波長帯でのclumped isotopeの吸収ピークに対し、高精度測定に必要な試料ガスの条件(温度、圧力など)を評価した。さらに、既存のガスセルと広帯域波長可変な外部共振器型中赤外量子カスケードレーザーを用いてCO2のCRDSを行い、clumped isotopeである13C16O18O、13C16O17O、13C18O2の吸収ピークを測定できることを示した。この基礎実験を通じて、試料ガス導入系とガスセルについての問題点を抽出した。
    2. 試料導入法の開発と分析性能評価
    ・大気CO2や炭酸塩を対象とした高精度なclumped isotopeの存在比測定を行うために、真空系によるCO2精製装置および炭酸塩のリン酸分解装置の開発に着手した。また、CRDS法の分析性能を評価するための試料の調製・準備を行った。
    製品の調達に時間がかかるなどの問題があり、想定外の遅れが一部にあるものの、初年度に計画した内容を実施することができたため。
    ガスセル内の圧力を高精度に制御する必要があることが明らかとなっており、その対策を検討する必要があるが、計画通り研究を推進する予定である。

    長期間の気候変動データは、日射量等の変化に対する気候システムの応答を理解することに加え、気候シミュレーションの予測精度の向上のためにも必須といえる。近年、洞窟の鍾乳石の一種である石筍を用いた気候復元の研究が急速に拡大している。しかし、日本においては、大型の石筍が少なく、連続的なデータを得ることが困難であった。そこで、本計画では、洞窟内において、フローストーンと呼ばれる鍾乳石を掘削することで、連続かつ高時間分解能な気候変動データの取得を目指す。掘削したコアの安定同位体比や流体包有物の分析によって、過去の日本地域における気候変動の実態とその変動メカニズムを解明する。
    本計画では、主に沖縄地域の洞窟内で鍾乳石を掘削し、鍾乳石コアを採取することで、連続・高時間分解能の環境・気候変動のデータを得る。さらに、鍾乳石内に閉じ込められた流体包有物の同位体比分析をおこなうことで定量的な気候復元を行う。具体的な研究は以下の2点について実施した。
    (1)洞窟内でのボーリングコアを掘削:昨年度の沖縄本島での調査結果を踏まえて、本年度は沖縄県南大東島の山下洞において掘削を実施した。新型コロナウィルス感染症対策等によって、離島での掘削の実施は危ぶまれたものの12月に無事に実施することができた。洞内では4か所でのコア掘削により7本の石筍コアを得た。最長の試料は計126 cmのコア試料(異なる2本の石筍の可能性もある)であり、目視で見る限り昨年度の試料よりも土壌成分も少なく気候復元に適している良質な試料を得ることができた。一方で、成長軸からは部分的に逸脱していた。掘削作業は洞内の高い二酸化炭素濃度、固い石質、高湿度により掘削機材にとっても作業者にとっても過酷な環境であった。現在、これらの鍾乳石コアの切断・前処理を進め、年代測定、安定同位体比測定を進めている。
    (2)同位体・化学分析による気候変動データ
    昨年度改良した水蒸気連続フロー式の流体包有物の分析システムに参照試料を自動測定するためにオートサンプラーを組み入れる改良を行った。これにより、参照試料の測定は終夜運転が可能になった。また、分光式アナライザーの改良に向けた検討も行った。この装置を用いて国内の複数の鍾乳石の流体包有物同位体比測定を実施した。また、得られた試料の年代をウラン・トリウム法による放射性同位体分析をシンガポール南洋工科大学に於いて実施した。
    新型コロナウィルス感染症対策等によって、掘削や切断作業の遅れは発生したものの、2回目のコア掘削は1回目よりも良質の試料を得ることに成功した。炭酸カルシウムの酸素・炭素同位体比測定は機器の不調などもありやや遅延した。流体包有物の分析装置の測定は順調に進んだ。これらを総合的に判断して、「おおむね順調」とした。
    来年度は、鍾乳石コアの年代測定と同位体比分析を進める。また、これまでに得たデータの解析を進める。

  6. A new approach to determine age of deposition and paleoenvironment change in annually laminated tufa

    We investigated a new approach to determine age of deposition and paleoclimate changes in annually laminated tufa. Previous studies indicated that the conventional 14C and 234U-230Th methods is difficult for age determination of tufa. To solve this problem, we carried out the high-resolution analyses of stable isotope compositions in annually laminated modern-tufa and paleo-tufa of Nigori River of Asama volcano in central Japan.
    Modern tufa δ18O from the riverbed reflected the variation in temperature of river water. Based on the results, we investigated pattern matching between the 25-years paleo-tufa δ18O record of summertime-averaged values and the last 2000 years record of tee-ring width. Results indicated statistically significant six ages, which implies that this approach has a difficulty in uniquely determining the depositional age. However, our approach suggests that the tufa occurrence and geochemical results can constrain the estimated ages.

    We reconstructed surface water temperature and salinity using ratios of oxygen isotope and minor metal for living and fossil coral annual bands collected from the Sekisei Lagoon in the Ryukyu Islands. The U-Th dating method was used for re-evaluation of the age determination. The U-Th dating results indicated that the two long-lived fossil coral samples were inhabited during almost the same period, so a rigorous evaluation of the reproducilibity of environmental reconstruction was conducted.
    The water temperature during the medieval climatic anomaly was found to be about 2 deg. C lower in summer and 1 deg. C higher in winter than at present throughout the habitat period. It was also found that there was a climatic regime shift in C.E. 1040, specifically a weakening of the East Asian Summer Monsoon.

    All molecules are composed of a large number of isotope-substituted molecular species (collectively referred to as isotopologues in this subject), but most of them have not yet been accurately measured. We developed these measurement methods and promptly applied the developed measurement methods to make them an international standard global environmental diagnostic method.
    By measuring the natural abundance of isotopologues of important environmental substances, and analyzing the important processes among the three processes of geology, organisms, and humans, the material cycle changes in the earth's surface environment determined by each process and its interaction. Thus, we created a method for environmental diagnosing at the molecular level.
