ISOTOPIC COMPOSITION DATA ALONG A 700-M LONG MIZUHO CORE

スポンサーリンク

概要

• 論文の詳細を見る

• It is estimated that the 700-m long core corresponds with the time period of the past 9400 years. Isotopic composition profile of the core, hence, would represent the temperature variation during the Holocence. Since Mizuho Station is located on a flowing ice sheet, however, ice at deep depths formed at rather higher elevations. In addition, total gas content measurements revealed that the ice sheet has started thinning at around 1000 years B. P. For constructing the past temperature variation from the core data, therefore, these two effects of downslope movement and ice sheet thinning have to be taken into account.
