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

这笔赠款支持对明尼苏达大学国家湖泊岩心储存库和初始岩心分析实验室的15个月持续支持。这一支持正式将初始岩心分析实验室(湖相研究中心-LRC)的活动与国家湖泊岩心储存库(LacCore)的活动合并。LRC经营开放式实验室，使社区能够获得专门的现场和实验室设备以及工作人员在初始岩心描述(ICD)方法方面的专门知识，包括非破坏性多传感器岩心测井和数字岩心摄影。LacCore设施将核心材料冷藏起来，并维护相关数据档案。自2000年LacCore基金开始运作以来，这两个设施一直在共生运作。新合并的设施将保留LacCore的绰号，并将继续为湖泊沉积物社区提供支持，包括全球湖泊钻探(GREAD)探险的野外和实验室方面，这些探险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，用于有助于我们了解大陆过去的气候、生态系统和生物地球化学动力学的研究。更广泛的影响包括提供面向服务的、低成本的集中式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好处，以及对本科生和研究生进行岩心描述和分析方法培训。该设施还将扩展目前的研讨会课程，作为明尼苏达州美洲原住民初中和高中环境夏令营的一个单元。

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.***
