  • 現場型蛍光センサーによるインド洋における 蛍光性有機物の子午面分布

    重光 雅仁, 内田 裕, 横川 太一, 村田 昌彦 日本地球化学会年会要旨集 68 (0), 29-, 2021

    <p>空間解像度の高い蛍光性有機物(FOM)データを得るために、現場型蛍光センサーを使用することを試みた。本研究では、インド洋の北端から南極大陸近傍まで当該センサーを用いてFOMの子午面分布を明らかにした。得られたFOM濃度については、センサーの温度依存性の補正を施し、また手分析で別に測定したFOMデータを用いてキャリブレーションを実施した。このデータを解析した結果、海盆スケールでのFOM回転時…
