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.***

1462297 ITO明尼苏达大学 - 双城和德卢斯（EAR-1462347）校园之间的这项合作赠款支持了Laccore的重新授予部分运营和实验室改进的资金，这是国家多用户湖沉积物核心核心档案和分析设施。 Laccore以前在EAR-0949962和EAR-0949285下得到了支持。Laccore设施为林科社区提供支持的研究，以有助于我们对过去的气候，生态系统和生物地球化学动态的理解，尽管详细的Satimentological Anallity and Cartival Services for Lactrotine Cores cores cores colles caltival collection commine complocials complocials complocials consection和。 Laccore运营开放实验室，以允许社区访问专业的现场和实验室设备以及员工专业知识，以进行初始核心描述（ICD）方法，包括：核心拆分；非破坏性多传感器核心记录； XRF核心扫描； SEM成像；骑生物学的准备；晶粒尺寸分析；碳库型；通过X射线衍射的相位识别；生物二氧化硅分析；准备样品以进行随后的稳定同位素分析；数字核心摄影和光学岩石学/涂片幻灯片分析。 Laccore还为湖泊加油探险公司提供了冷藏和冷冻的核心存储和档案服务以及野外芯设备和策展材料（D-管）支撑。 LacCore的工作人员负责策划湖核心ICD元数据，并将所有数据的常规传输传输到NOAA国家地球物理数据中心，开发用于核心图像分析和相关性软件以及教育和外展活动，包括为美国原住民部落资源管理者提供建议明尼苏达州，支持学生旅行赠款，以使学生了解核心描述和分析的标准协议，并开发社交媒体和智能电话应用程序，以支持地球科学教育和公众意识。 随着明尼苏达大学作为新的大陆科学钻探协调办公室（CSDCO; EAR-1338322）的选择，取代了曾经由DOSECC管理的角色，Laccore PIS现在将参与大型钻探项目计划和执行。设施将继续作为训练和核心分析技术的数百名研究人员，特别是研究生的培训理由。 Laccore员工从事教育和宣传活动，包括一个正在进行的合作项目，旨在研究明尼苏达州北部的野生水稻湖泊的古环境，部落大学生以及来自苏必利尔湖奇珀瓦湖和Fond du Lac Tribal和Fond du Lac Tribal and Communital College的老师。 LacCore的工作人员积极从事外展活动，以支持代表性不足的学生参与地球科学。 可以通过基于Web的开放数据档案来访问LACCORE数据，Laccore员工积极维护和开发软件工具，有助于对湖核心记录进行成像和解释。***
