Acquisition of a CO2 Coulometer and a Laser-Diffraction Particle-Size Analyzer for the Sediment Analysis Laboratory at East Carolina University

这笔赠款为购买粒度分析仪和二氧化碳库仑分析仪以分析沉积物样品的总有机碳和无机碳含量提供了部分支持。这种分析沉积物特征的基本设备将有助于东卡罗来纳大学地质学系正在进行和计划进行的古气候和沉积学研究。玻利维亚高原是南半球为数不多的低纬第四纪古气候沉积档案之一，对该地区的湖泊和河流沉积物的研究应该会对低纬气候波动及其对安第斯高地人类住区的影响产生新的见解。此外，研究外滩堰塞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1999年的弗洛伊德飓风)的沉积学反应，是该系教员自然关注的重点，该系位于世界上研究堰塞滩和河口动力学的大型自然实验室之一附近。*

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.***
