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

这笔拨款将持续支持明尼苏达大学的国家湖泊岩心储存库和初始岩心分析实验室（LacCore）三年。LacCore运营开放式实验室，允许社区获得专业领域和实验室设备以及初始岩心描述（ICD）方法的工作人员专业知识，包括无损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档案服务。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 （Global LAkes Drilling）项目中回收的，其余20%的岩心材料来自较小的湖泊取心项目。预计在支助期间将扩大档案。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薪水。该设施为湖泊研究界提供研究服务，有助于我们了解大陆上过去的气候、生态系统和生物地球化学动力学。LacCore对本科生和研究生进行核心描述和分析方法的培训，设施工作人员参加明尼苏达州美国土著初中和高中环境营地的推广活动。

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.
