Collaborative Research: Facility Support: National Lacustrine Core Facility (LacCore)

这项明尼苏达大学双城分校和德卢斯分校（EAR-1462347）之间的合作拨款，为LacCore的运营和实验室改进提供了新的部分资金支持，LacCore是一个国家多用户湖泊沉积物核心档案和分析设施。LacCore先前在EAR- 09499962和EAR- 0949285下得到支持。LacCore设施通过详细的沉积学分析和湖泊岩心档案服务，支持湖沼学社区的研究，这些研究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核心描述（ICD）方法的工作人员专业知识，包括：核心分裂；无损多传感器岩心测井；XRF岩心扫描；扫描电镜成像;孢粉学的准备;粒度分析；碳电量分析;x射线衍射相识别；生物硅分析；为随后的稳定同位素分析准备样品；数码岩心摄影，光学岩石学/涂片分析。LacCore还提供冷藏和冷冻岩心存储和档案服务，以及现场岩心设备和策展材料（d管）支持湖泊岩心探险。LacCore的工作人员负责管理湖芯ICD元数据，并将所有数据例行传输给NOAA。美国国家地球物理数据中心，核心图像分析和相关软件的开发，以及教育和推广活动，包括为明尼苏达州的美国土著部落资源管理人员提供建议，支持学生旅行补助金，使学生接触核心描述和分析的标准协议，以及开发社会媒体和智能手机应用程序，以支持地球科学教育和公众意识。随着明尼苏达大学被选为新的大陆科学钻井协调办公室（CSDCO; EAR- 1338322），取代了过去由DOSECC管理的角色，LacCore pi现在将参与大型钻井项目的规划和执行。LacCore设施将继续作为数百名研究人员，特别是研究生，在取心和岩心分析技术方面的培训基地。拉科的工作人员从事教育和外联工作，包括一个正在进行的合作项目，旨在研究明尼苏达州北部野生稻湖的古环境，合作对象是苏必利尔湖奇佩瓦湖丰迪拉克部落学院和丰迪拉克部落和社区学院的部落大学生和教师。LacCore工作人员积极参与外展活动，以支持代表性不足的学生参与地球科学。LacCore数据可通过基于网络的开放数据档案访问，LacCore工作人员积极维护和开发软件工具，以协助湖泊岩心记录的成像和解释

1462297 Ito This collaborative grant between the University of Minnesota - Twin Cities and Duluth (EAR-1462347) campuses supports renewed partial funding of operations and laboratory improvements at LacCore, a national multi-user lake sediment core archival and analysis facility. LacCore was previously supported under EAR- 0949962 and EAR- 0949285. The LacCore Facility supports the limnological community for studies that contribute to our understanding of past climates, ecological systems, and biogeochemical dynamics on the continents though detailed sedimentological analysis and archival services for lacustrine cores. LacCore operates open laboratories to allow community access to specialized field and laboratory equipment and staff expertise for Initial Core Description (ICD) methods including: core splitting; non-destructive multi-sensor core logging; XRF core scanning; SEM imaging; palynological preparation; grain size analysis; carbon coulometry; phase identification via x-ray diffraction; biogenic silica analysis; preparation of samples for subsequent stable isotopic analysis; digital core photography, and optical petrography/smear slide analysis. LacCore also provides refrigerated and frozen core storage and archival services and field coring equipment and curatorial materials (D-tubes) support for lake coring expeditions. LacCore staff are responsible for curation of lake core ICD metadata and the routine transmission of all data to NOAA?s National Geophysical Data Center, development of software for core image analysis and correlation, and education and outreach activities including advising Native American tribe resource managers in the state of Minnesota, supporting student travel grants to expose students to standard protocols for core description and analysis, and developing social media and smart phone applications in support of geoscience education and public awareness. With the selection of the University of Minnesota as the new Continental Scientific Drilling Coordination Office (CSDCO; EAR- 1338322), replacing a role that used to be managed by DOSECC, LacCore PIs will now engage in large drilling project planning and execution.The LacCore Facility will continue as a training ground for hundreds of researchers, particularly graduate students, in coring and core analysis techniques. LacCore staff are engaged in education and outreach including an ongoing collaborative project aimed at study of the paleoenvironments of wild rice lakes in northern Minnesota with tribal college students and teachers from the Fond du Lac Band of Lake Superior Chippewa and Fond du Lac Tribal and Community College. LacCore staff actively engage in outreach activities to support the engagement of underrepresented students in the geosciences. LacCore data are accessible via web-based open data archives and LacCore staff actively maintain and develop software tools that assist in the imaging and interpretation of lake core records.***
