Facilities Support: National Lacustrine Core Repository and initial Core Analysis Laboratory (LacCore)

0519258 ItoThis grant supports a fifteen month continuation of support for a national lakeine core repository and initial core analysis laboratory at the University of Minnesota.该基金将继续支持明尼苏达大学的国家湖相岩心储存库和初始岩心分析实验室。 这种支持正式合并了最初的核心分析实验室（湖沼研究中心-LRC）的活动与国家湖泊核心储存库（LacCore）。 LRC运营开放实验室，让社区获得专业的现场和实验室设备以及工作人员的专业知识，用于初始岩心描述（ICD）方法，包括非破坏性多传感器岩心测井和数字岩心摄影。 LacCore设施在冷藏条件下储存堆芯材料，并保存相关数据档案。 自2000年LacCore资助开始以来，这两个设施一直共生运作。 新合并的设施将保留名称LacCore，并将继续运营，以支持湖泊沉积物社区，包括全球GLAD（全球湖泊钻探）探险的现场和实验室方面，收集数百至数千米的沉积物。该设施将服务于湖沼学社区的基础设施需求，以促进我们对大陆过去气候，生态系统和生物地球化学动力学的理解。 更广泛的影响包括提供面向服务的、低成本的、集中的湖泊沉积物核心设施，为在许多机构工作的科学家提供重大利益，以及对本科生和研究生进行核心描述和分析方法的培训。 该设施还将扩大目前的研讨会课程，作为明尼苏达州美洲原住民初中和高中环境营地的一个单元。

0519258ItoThis grant supports a fifteen month continuation of support for a national lacustrine core repository and initial core analysis laboratory at the University of Minnesota. This support formally merges activities of the initial core analysis laboratory (Limnological Research Center -LRC) with the national lacustrine core repository (LacCore). The LRC operates open laboratories to allow community access to specialized field and laboratory equipment and staff expertise for Initial Core Description (ICD) methods including non-destructive multi-sensor core logging and digital core photography. The LacCore facility stores core materials under refrigeration and maintains related data archives. These two facilities have operated symbiotically since the beginning of LacCore funding in 2000. The newly merged facility will retain the moniker LacCore and will continue to operate in support of the lake sediment community including both field and lab aspects of worldwide GLAD (Global LAkes Drilling) expeditions that collect hundreds to thousands of meters of sediment. The facility will serve the infrastructure needs of the limnological community for studies that contribute to our understanding of past climates, ecological systems, and biogeochemical dynamics on the continents. Broader impacts include the availability of a service-oriented, low-cost, centralized lake sediment core facility that provides significant benefits to scientists working at many institutions, and the training of undergraduate and graduate students in methods of core description and analysis. The facility will also expand a current workshop course as a unit for Native American middle- and high school environmental camps in Minnesota.***
