Acquisition of a Multi-Sensor Core-Logger in Support of the Multi-User LRC Core Facility

该拨款为获取多传感器岩心记录仪（MSCL）提供部分支持，用于自动分析湖泊岩心的基本物理特性。最先进的MSCL系统将从Geotek有限公司购买，并将增强现有的Geotek MCSL系统，该系统已经在明尼苏达大学湖沼学研究中心（LRC）安装和运行。LRC目前的MSCL已经运行了10年，但仅限于记录整个岩心剖面的纵波速度、伽马射线密度和磁化率。新的MSCL将允许对分离岩心进行测井，并将包括用于彩色成像、电阻率和更高分辨率磁化率采集的传感器。MSCL将支持对了解地球气候记录具有重要意义的国家和国际跨学科古湖泊学研究。MSCL将作为国际大陆科学钻探计划的一部分，用于对多个全球湖泊钻探项目的湖泊岩心进行初始岩心描述。来自的的喀喀湖、马拉维湖和贝加尔湖的湖泊沉积物最终将被明尼苏达大学存档，并由研究人员使用包括MSCL在内的LRC设备进行初步的岩芯描述。＊＊＊

0319203ItoThis grant provides partial support for the acquisition of a multi-sensor core logger (MSCL) for automated analysis of basic physical properties of lacustrine cores. A state-of-the-art MSCL system will be purchased from Geotek, Ltd. and will augment an existing Geotek MCSL already housed and operated at the Limnological Research Center (LRC) at the University of Minnesota. The current MSCL at the LRC has been in operation for the last ten years but is limited to logging whole-core sections for p-wave velocity, gamma-ray density and magnetic susceptibility. The new MSCL will allow for the logging of split cores and will include sensors for color imaging, electrical resistivity and higher resolution acquisition of magnetic susceptibility. The MSCL will support national and international interdisciplinary paleolimnological research of importance to understanding earth's climate record. The MSCL will be used as part of a program of initial core description of lake cores from multiple global lake drilling projects that are part of the International Continental Scientific Drilling Program. Lake sediments from lakes Titicaca, Malawi and Baikal will eventually be archived at the University of Minnesota and initial core descriptions carried out by investigators using LRC equipment including the MSCL. ***
