FIELDWORK

Research/Observation Title

East GReenland Ice core Project (EGRIP)

Research/Observation Purpose

氷床流動のメカニズム解明及び過去の気候・環境変動解明

Science Summary (common)

デンマークのコペンハーゲン大学が主導して実施する、東グリーンランド深層氷床掘削プロジェクト(EGRIP計画)に参加する。

Planning Period

Planning Start Year 2016 〜 Planning End Year 2021

- Individual Project Information 1/3 Research/Observation Period 2016-06-22 〜 2016-07-17

Science Summary

今年度は掘削場を整備した後、掘削を開始する。また、現場解析室(サイエンストレンチ)などの立ち上げがおこなわれる。我々日本の研究者は、現地で表層積雪の採取や4mピット観測、10mのアイスコア掘削を計画している。持ち帰った雪氷試料に含まれる様々な化学種を分析し、濃度レベルや同位体組成を明らかにする。またそれらの鉛直プロファイルから、観測地点における近年の雪の年間堆積量を復元する。
