Origins of Atmospheric Dust in GISP2 Ice

该奖项是为了支持一个为期一年的项目，该项目分析GISP2冰芯的尘埃样本，以获得它们可能的大陆来源区域的信息。研究人员试图分析来自几个气候时期（从全新世之前到现在）的样本，这些气候时期代表了极端的温暖和寒冷气候。将研究粉尘的矿物学和同位素组成，以帮助约束古大气环流和粉尘输送模式。这项研究将在同一项目的一个试点项目（OPP-9321910）中开始的工作继续进行一年。

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.
