This research is designed to document a high-precision record of terrestrial responses to the widespread and rapid ocean/atmosphere reorganization in and around the North Atlantic Ocean during the Younger Dryas Chronozone of the last deglaciation (11,000-10,000 years ago). The chronology and rates of change in vegetation and association climate during the Younger Dryas will be documented for land areas adjacent to the late-glacial Loch Lomond ice sheet over the Scottish Highlands. An AMS 14C chronology of changing paleo-vegetation will be used to document the timing of terrestrial biotic responses as a kind of bioassay for the rapid reorganization of the North Atlantic. In turn, lags in growth and dissipation of the ice sheet will be determined and cross- calibrated with the climate record from Scotland, Ireland and the North Atlantic. Results of this work will define the boundary conditions needed to develop and test several numerical models of growth and response of ice-sheet to major, abrupt, and transient climate shifts of the past and future. One such model of ice-sheet dynamics will be developed and tested as part of the project.

这项研究旨在记录一个高精度的记录 地球对大范围快速的 北大西洋及其周围的海洋/大气重组 末次冰消期新仙女木时期的海洋 (11 000 - 10000年前）。 2000年的时间表和变化率 新仙女木期的植被和气候 记录冰川晚期洛赫附近的陆地区域 苏格兰高地上的洛蒙德冰盖。 AMS 14 C年表 将被用来记录 作为一种快速的生物测定， 北大西洋重组。 反过来，增长滞后， 冰盖的消散将被确定并跨越- 根据苏格兰、爱尔兰和 北大西洋。 这项工作的结果将确定边界 开发和测试几个数值模型所需的条件 冰盖的生长和对主要的、突然的和瞬时的响应 过去和未来的气候变化。 一个这样的冰盖模型 作为该项目的一部分，将开发和测试动态。
