The PI's request funds to acquire state-of-the-art instrumentation for the quantitative chemical and physical analysis of sediment and rock cores for paleoclimatic and sedimentary research. The goal is to create an integrated new facility at the University of Miami that will combine the latest technology for the rapid and automated measurement of sediment/rock geochemical, optical, and petrophysical properties. The suite of new instruments, when combined with existing wet chemical analytical facilities, will allow for comprehensive, in-house, one-stop study of sediment and rock cores from marine, lake and wetland sites. The instruments we proposed include: (1) an Avaatech X-Ray Fluorescence Core Scanner to be used for the rapid and non-invasive elemental analysis of split sediment cores; (2) a GEOTEK Multi-Sensor Core Logger equipped with color line-scan camera system to be used for the digital imaging and direct physical property measurement of both whole and split rock and sediment cores; and (3) a replacement X-Ray Diffractometer that is needed for the quantitative determination of mineralogy. Broader Impacts:The proposed equipment acquisition would contribute significantly to an active sedimentary research group at the University of Miami, and to other universities in the South Florida area. On a national scale, the instruments would contribute to a significant improvement over existing US capabilities in paleoclimate and paleoenvironmental research. The equipment will be used for graduate and undergraduate student training.

PI的要求资金，以获得国家的最先进的仪器，定量化学和物理分析的沉积物和岩石核心的古气候和沉积研究。目标是在迈阿密大学建立一个综合的新设施，该设施将联合收割机与最新技术相结合，用于快速自动测量沉积物/岩石的地球化学、光学和岩石物理特性。这套新仪器与现有的湿化学分析设施相结合，将能够对海洋、湖泊和湿地的沉积物和岩芯进行全面的、内部的、一站式的研究。我们提出的仪器包括：（1）Avaatech X射线荧光岩心扫描仪，用于对分离的沉积物岩心进行快速和非侵入性的元素分析;（2）GEOTEK多传感器岩心记录仪，配备彩色线扫描摄像系统，用于对完整和分离的岩石和沉积物岩心进行数字成像和直接物理性质测量;以及（3）矿物学定量测定所需的替代X射线衍射仪。更广泛的影响：拟议的设备购置将大大有助于迈阿密大学的一个活跃的沉积研究小组，以及南佛罗里达地区的其他大学。 在国家范围内，这些仪器将有助于显着提高美国在古气候和古环境研究方面的现有能力。这些设备将用于研究生和本科生培训。
