Doctoral Dissertation Research: Inland Eolian Dunes in Georgia: Age, Morphology and Paleoclimatic Implications

格鲁吉亚大学 博士论文研究将确定沙丘活动在格鲁吉亚的年龄，描述沙丘的地貌和地层背景，并使用由此产生的信息来推断产生沙丘的过程和环境条件。 沙丘活动的年龄将采用光释光测年法确定，并辅之以加速器质谱仪放射性碳测年法提供的年龄数据。 结果将产生自然气候变化的记录，并说明全球气候波动对风沙活动的影响。

Ivester, Andrew University of Georgia The doctoral dissertation research will determine the ages of dune activity in Georgia, describe the geomorphic and stratigraphic context of the dunes, and use the resulting information to infer the processes and environmental conditions that produced the dunes. Ages of dune activity will be determined using optically stimulated luminescence (OSL) dating with supplementary age data from accelerator mass spectrometer (AMS) radiocarbon dating. Results will yield a record of natural climatic variability and illustrate the effects of global climate fluctuations on eolian activity.
