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

0080605Rigsby该赠款提供部分资助，用于购置一台粒度分析仪和一台二氧化碳库仑计，以分析沉积物样品的有机和无机碳总含量。 这种分析沉积物特性的基本设备将有助于东卡罗莱纳大学地质系教员进行中和计划中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度第四纪古气候的沉积档案之一，对该地区湖泊和河流沉积物的研究应能使人们对低纬度气候波动及其对高安第斯山脉人类定居的影响有新的认识。 此外，研究外银行屏障岛系统的全新世发展和这些系统和沿海平原河口的沉积学响应频繁的大风暴事件（即飓风弗洛伊德，1999年）是该部门的教师的自然焦点，该部门位于世界上最大的天然实验室之一，用于屏障海滩和河口动力学的研究。

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.***
