Origins of Atmospheric Dust in GISP2 Core Ice

调查人员将继续从格陵兰冰盖项目2冰芯中提取灰尘样本的项目。 尘埃的来源将通过比较来自冰芯的尘埃的地球化学与从世界各地潜在大陆来源采集的样本来确定。 冰芯中尘埃来源区域的变化将揭示在过去10万年中大陆风化和大气传输是如何随着气候变化而变化的。大气迁移模式的变化将为测试气候模型提供数据，这些模型可预测冰川期和间冰期极端气候事件期间的大气条件变化。.

Investigators will continue a project of extracting dust samples from the Greenland Ice Sheet Project 2 ice core. The origin of the dust will be determined by comparing the geochemistry of the dust from the ice core to that of samples taken from potential continental sources worldwide. Changes in the source area for the dust in the ice cores will reveal how continental weathering and atmospheric transport have changed in response to changing climate during the past 100,000 years. Changes in atmospheric transport patterns will provide data for testing climate models that predict changes in atmospheric conditions during climate events during both glacial and interglacial climate extremes. .
