0080605RigsbyThis grant provides partial support of the costs of acquiring both a particle size analyzer and a carbon dioxide coulometer for the analysis of the total organic and inorganic carbon contents of sediment samples. This basic equipment of the analysis of sediment characteristics will facilitate ongoing and planned paleoclimatic and sedimentological research by faculty in the Geology Department at East Carolina University. Studies of lacustrine and riverine sediments cored in the Bolivian Altiplano, one of the few sedimentary archives of low latitude Quaternary paleoclimates in the southern hemisphere, should yield new insights into low latitude climate fluctuations and its influence on human settlement in the high Andes. Additionally, studies of the Holocene development of the Outer Banks barrier island system and the sedimentological response of these systems and coastal plain estuaries to frequent large storm events (i.e. Hurricane Floyd, 1999) are a natural focus of faculty in this department proximally located to one of the world's great natural laboratories for the study of barrier beach and estuarine dynamics.***

0080605Rigsby这笔赠款提供了部分支持购买粒度分析仪和二氧化碳库仑计的费用，用于分析沉积物样品的总有机碳和无机碳含量。 这种沉积物特征分析的基本设备将促进东卡罗来纳大学地质系教师正在进行和计划进行的古气候和沉积学研究。 对玻利维亚高原（南半球低纬度第四纪古气候为数不多的沉积档案之一）的湖泊和河流沉积物的研究，应该会对低纬度气候波动及其对安第斯山脉高地人类居住的影响产生新的见解。 此外，外滩障壁岛系统的全新世发展以及这些系统和沿海平原河口对频繁的大型风暴事件（即飓风弗洛伊德，1999）的沉积学响应的研究是该系教师的自然焦点，该系的教师靠近一个世界上研究障壁海滩和河口动力学的伟大自然实验室。***
