This ESH project will use ocean and atmospheric models to reconstruct conditions at the last glacial maximum and to calculate the response of the climate to meltwater pulses during deglaciation. The models will include oxygen isotope tracers in seawater and in atmospheric water vapour and these will be used, in conjunction with ecologic models, to estimate carbonate oxygen isotopes values in planktonic foraminifera and coral. The calculated glacial-age deep sea sediment and coral. Results from this project will test the ability of models to simulate different climates and help quantify climate changes over the last 20,000 years.

这个ESH项目将使用海洋和大气模型来重建末次冰期最大期的条件，并计算冰川消退期间气候对融水脉冲的响应。 这些模型将包括海水和大气水蒸气中的氧同位素示踪剂，这些示踪剂将与生态模型一起用于估计浮游有孔虫和珊瑚中的碳酸盐氧同位素值。 计算出的冰河时期深海沉积物和珊瑚。 该项目的结果将测试模型模拟不同气候的能力，并帮助量化过去20，000年的气候变化。
