This award supports a program to study sediment cores from the Hudson Strait, which is widely believed to have been the drainage path for a major part of the Laurentide Ice Sheet. The goals are to understand the dynamic processes associated with the last stages of collapse of this marine based ice sheet. The project will use oxygen isotopes, carbon-14 ages, benthic foraminifera, and sediment provenance studies to develop a history of the changing paleoenvironmental conditions during the time that the Laurentide Ice Sheet was deteriorating.

该奖项支持一项研究沉积物岩心的计划， 哈德逊海峡，这被广泛认为是排水 这是劳伦蒂德冰盖的主要部分。 这些目标是 去理解与最后一个 这片海洋冰盖的崩溃阶段。 项目 将使用氧同位素，碳14年龄，底栖有孔虫， 和沉积物来源研究， 改变了古环境条件， 劳伦蒂德冰盖正在恶化。
