Facility Support: National Lacustrine Core Repository and Initial Core Analysis Laboratory (LacCore)

三年的持续支持国家湖泊核心存储库和初始核心分析实验室在明尼苏达大学（LacCore）提供了这笔赠款。 LacCore运营开放式实验室，允许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还提供冷藏核心存储和存档服务。 LacCore目前拥有超过6000米的湖芯。 大约80%的岩心材料是从全球范围内进行的GLAD（全球湖泊钻探）项目中回收的，其余20%的岩心材料来自较小的湖泊取芯项目。 预计在支助期间档案将扩大。 资金为全职核心存储库管理员和核心分析实验室经理提供工资。 该设施服务于湖沼学研究社区的研究，有助于我们了解过去的气候，生态系统和大陆上的地球化学动力学。 LacCore培训本科生和研究生核心描述和分析的方法和设施的工作人员参加外展活动，以美国土著初中和高中环境营地在明尼苏达州。

Three years of continued support of a national lacustrine core repository and initial core analysis laboratory at the University of Minnesota (LacCore) is provided by this grant. LacCore 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. LacCore also provides refrigerated core storage and archival services. LacCore currently houses in excess of 6000 m of lake cores. Roughly 80% of core materials were recovered from GLAD (Global LAkes Drilling) projects conducted worldwide, the remaining 20% of core materials are from smaller lake coring projects. Expansion of the archive over the period of support is anticipated. Funding provides salary for a full-time core repository curator and core analysis lab manager. The facility serves the limnological research community for studies that contribute to our understanding of past climates, ecological systems, and biogeochemical dynamics on the continents. LacCore trains undergraduate and graduate students in methods of core description and analysis and facility staff participate in outreach activities to Native American middle- and high school environmental camps in Minnesota.
