项目摘要

EAR-0447165LowensteinUpgrading the Binghamton University Geoscience microscopy/fluid inclusion laboratory involves obtaining new equipment that will facilitate ongoing NSF-funded research projects on the chemistry of ancient seawater and geobiology. Current research involves searching for microorganisms and ancient DNA trapped in brine inclusions for periods of 104-106 years in Quaternary salt cores from three basins (Death Valley, Salar de Atacama, Chile, and Salar de Uyuni, Bolivia). The goal is to obtain data on the distribution, survival, and diversity of microorganisms in fluid inclusions in saline minerals that have been in the subsurface for periods of several hundred thousand years. These projects require identification of micron-size organisms in fluid inclusions in crystals. The optical microscope system purchased with this grant will facilitate observation of microbes. Fluid inclusion drilling and extraction will be facilitated with the purchase of a precision drill and mount for motion control; a laminar flow hood would protect brine inclusions from contamination. An upgrade of the miscroscopy/fluid inclusion laboratory will benefit the students and faculty in the Department of Geological Sciences at Binghamton University. Undergraduate and graduate students will receive instruction and training in the use of equipment, and several courses will use the laboratory for instruction. Summer workshops will be organized to provide training and curriculum development for local middle school and high school teachers in geobiology; the microscopy/fluid inclusion laboratory will be used for these workshops.

升级宾厄姆顿大学地球科学显微镜/流体包裹体实验室涉及获得新设备，这将有助于正在进行的NSF资助的古海水化学和地球生物学研究项目。目前的研究涉及在三个盆地（智利的阿塔卡马盐沼（Salar de Atacama）的死亡谷和玻利维亚的乌尤尼盐沼（Salar de Uyuni））的第四纪盐岩中寻找104-106年的盐水包裹体中捕获的微生物和古DNA。其目标是获得关于盐水矿物流体包裹体中微生物的分布、存活和多样性的数据，这些矿物已经在地下存在了几十万年。这些项目需要鉴定晶体中流体包裹体中的微米级生物。用这笔赠款购买的光学显微镜系统将有助于观察微生物。通过购买精密钻头和运动控制支架，将有助于流体包裹体钻孔和提取;层流罩将保护盐水包裹体免受污染。显微镜/流体包裹体实验室的升级将使宾厄姆顿大学地质科学系的学生和教师受益。本科生和研究生将接受设备使用方面的指导和培训，几门课程将使用实验室进行指导。将举办暑期讲习班，为当地初中和高中教师提供地球生物学方面的培训和课程编制;显微镜/流体包裹体实验室将用于这些讲习班。
