Abstract This award is for support for a one year project to analyze dust samples from the GISP2 ice core to yield information on their possible continental source areas. The investigators seek to analyze samples from several climatic periods (pre-Holocene to present) representing both warm and cold climate extremes. The mineralogy and isotopic composition of the dust will be studied in order to aid in constraining models of paleo-atmospheric circulation and dust transport. This study continues, for an additional year, work begun in a pilot project (OPP-9321910) on the same project.

该奖项是对一个为期一年的项目的支持，该项目旨在分析来自GISP2冰芯的尘埃样本，以获得有关其可能的大陆源区的信息。研究人员试图分析几个气候时期(从全新世之前到现在)的样本，这些样本代表了气候极端的温暖和寒冷。将研究尘埃的矿物学和同位素组成，以帮助建立古大气环流和尘埃输送的约束模型。这项研究将在同一项目的试点项目(业务伙伴关系-9321910)中开始的工作再继续一年。
