NIPR special seminar / 極地研特別研究談話会(Nov 28, 2016)
国立極地研究所の特別研究談話会の情報が届きましたのでお知らせします。グリーンランドにおけるアイスコアの解析結果と氷床の変動に関するセミナーです。講師はコペンハーゲン大学のDorthe Dahl-Jenseさんです。詳しくは以下をご覧ください。


日時: 11月28日(月)13:30-14:40
場所:国立極地研究所 3階セミナー室(C301)

【講演者】 Dorthe Dahl-Jensen(Niels Bohr Institute, University of Copenhagen)

【タイトル】
The Centre for Ice and Climate – our research
The Greenland ice cores tell tales on the past climate and the evolution of the Greenland Ice Sheet.

【要旨】
The vision of the Centre of Excellence for Ice and Climate is to contribute to an improved understanding of the present and past warm interglacial periods by studying ice cores, and developing models to explain observations and predict the ice sheet response to climate change.

We have drilled several deep ice cores through the Greenland ice sheet with the ice core drills developed by our group.

Knowledge on the long-term response of the Greenland ice sheet to climate warming during past interglacials is essential for estimating the potential of future rise in sea level. During the last million years, the Greenland Ice Sheet (GRIS) has waxed and waned in response to glacial and interglacial periods. The deep ice cores through the Greenland ice sheet contain ice from the time ice covered the site. Ice from the last interglacial period (the Eemian, LIG) 130 to 115 kyears before present is present in most of the deep ice cores and can be used to determine both temperature and extent of the ice sheet during this warm interglacial period.

Going to the bed, basal material enclosed in the ice cores contain DNA remnants that can be used to determine the ecosystems present before ice covered Greenland.

The reaction of the Greenland ice sheet to climate changes and the sea level change from mass loss from the Greenland ice sheet is discussed based on the ice core findings.
