Outline of Annual Research Achievements

本研究の目的は、冬季海氷域の大気-海氷-海洋間の炭素および物質輸送プロセスを明らかにすることである。これまでの調査では、気候条件の厳しさやプラットフォームの整備が課題となり、冬季の氷上野外観測は実現困難であった。そこで本研究では、冬季の観測を集中的に実施した。特に今年度は、

(1) アルフレッドウェゲナー極地海洋研究所(ドイツ)が所有する砕氷船ポーラシュテルンを用いた厳冬期南極海(2013年6-8月)で採取したサンプルの分析作業を実施した。分析結果を組み合わせ、大気―海氷間の二酸化炭素とブロモホルム交換量の評価/変動要因を明らかにした。上記分析で得られた結果をまとめ、国際学会および国内学会で成果発表した。現在、国際査読誌への投稿に向けて執筆作業を進めている。

(2) ノルウェー極地研究所(ノルウェー)が所有する砕氷船ランセを用いた厳冬期北極海航海(2015年2-3月)に参加し、氷上観測を実施した。観測サイトでは、海氷上積雪、海氷、海氷下海水を採取した。また、大気―海氷間の二酸化炭素とブロモホルム交換量の測定を実施した。特に、大気―海氷間の二酸化炭素交換量の測定では、気温による交換量の変化、積雪による交換量の抑制に関する貴重なデータを取得した。今後、各研究機関での分析、データ解析をする。そして、分析結果、取得データ解析をまとめ、国際学会および国内学会で成果発表する。最終的に(1)(2)を組み合わせ、冬季海氷域の大気-海氷-海洋間の炭素および物質輸送プロセスを明らかにする。
