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. ***

0319203ItoThis grant provides partial support for a purchase of a multi-sensor core logger（MSCL）for automated analysis of basic physical properties of lacusine cores. 一个最先进的MSCL系统将从Geotek有限公司购买，并将增加现有的Geotek MCSL已经安置和运行在湖泊研究中心（LRC）在明尼苏达大学。 目前LRC的MSCL已经运行了十年，但仅限于记录整个岩心剖面的P波速度、伽马射线密度和磁化率。 新的MSCL将允许对分裂岩心进行测井，并将包括彩色成像、电阻率和更高分辨率的磁化率采集传感器。 MSCL将支持国家和国际跨学科的古湖沼学研究的重要性，了解地球的气候记录。 MSCL将被用于对来自多个全球湖泊钻探项目的湖芯进行初始岩心描述的计划的一部分，这些项目是国际大陆科学钻探计划的一部分。 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在明尼苏达大学存档，并由调查人员使用LRC设备（包括MSCL）进行初步岩心描述。***
