Outline of Final Research Achievements

The Antarctic coastal system with ice sheet, sea ice, and ocean components has a significant influence on global thermohaline circulation and sea-level changes, and thus climate change. This study is observational research on the East Antarctic coastal system, where the observational findings are quite sparse. The primary findings of this study are; (1) basal melt process beneath Shirase Glacier Tongue caused by warm water inflow, (2) characteristics of warm water distribution in front of Totten Ice Shelf and surrounding ocean, (3) seasonal variability in properties/distributions of dense Shelf Water and offshore-origin warm water over the Cape Darnley Polynya.

Academic Significance and Societal Importance of the Research Achievements

特に,「データ空白域である棚氷近傍での海洋観測と棚氷の氷厚変化の直接観測を同時に実施し,海洋学と測地・雪氷学双方のアプローチから東南極沿岸システムにおける暖水流入の実態とその影響」について,主に観測研究により明らかにした点に学術的意義がある。これら現場観測を軸とした研究成果は,東南極沿岸システムの変動が全球規模の海洋熱塩循環や海水準変動へ与える影響を精度良く評価する上での基礎的知見となる。さらに,将来予測に欠かせない数値モデルの検証およびその精度向上にも貢献し,ひいては気候モデルにおける海洋熱塩循環や海水準といった全球環境将来予測スキルの発展に資する。
