Curation Of National Antarctic Sediment Collections

这项提议将为佛罗里达州立大学南极海洋地质研究设施(AMGRF)的继续运作提供资金。该设施是美国国家科学基金会南极洲周围海底沉积物岩芯的储存库，向整个科学界提供沉积物岩芯，为科学家收集样本进行专门测量提供必要的设备和知识。这些沉积物提供了过去气候、海洋环流和冰盖历史的记录，并以高昂的成本使用从科考船上部署的活塞岩芯和从钻井平台上进行的旋转取心来回收。这笔资金支持FSU的一名策展人、一名助理策展人和一名学生劳动力。这名工作人员支持来访的科学家，管理用于岩心表征和采样的收集和设备，并维护数据库。AMGRF拥有来自南大洋的独特沉积岩芯集合，在过去的50年里一直发挥着这一作用。佛罗里达州立大学的南极海洋地质研究设施是美国国家科学基金会的南大洋活塞和钻芯储存库，过去50年来，它一直在进行海洋地质研究，并在目前的大楼内为南极和地球科学共同体提供许多服务。该提案要求运营资金(A)继续提供这些服务，(B)管理档案和数据库，(C)完成AMGRF冷藏室的必要升级，以及(D)继续我们针对学生和公众的教育和外展计划。AMGRF对美国南极方案船只收集的23,000多米(7,000多个岩心)岩芯沉积物进行了存档和管理。该设施还存档和管理来自ANDRILL等国际项目的约5500米的旋转芯材料。标准岩心处理服务包括岩心分离、多传感器径迹分析、岩心摄影、全岩心X光等、岩心描述出版物(宏观和微观)和岩心采样。设施人员还应要求向外地项目提供策展支助服务。AMGRF的分析设备满足了设施人员(用于生成详细的岩心描述)、参与美国南极计划(USAP)的NSF首席调查人员以及来自美国和其他地区科学界的合格用户的研究需求。该设备为该设施的用户提供了必要的工具，以便快速和客观地分析每年送往该设施的活塞芯和钻芯。AMGRF维护一个核心和样本数据库，具有最新的地图样本搜索能力，可通过不断升级的设施网站进行访问。这个可搜索的数据库包含关于该设施储存的所有岩芯的基本信息，以及从1964年至今采集的样品的信息。除了沉积物岩心档案外，AMGRF还保存着船舶和甲板日志档案、大约862,000张显微镜幻灯片的集合，以及一个AMGRF相关出版物的图书馆。设施工作人员定期为学生和公众提供参观和讲座。

This proposal would provide funding for continued operation of the Antarctic Marine Geology Research Facility (AMGRF) at Florida State University. This facility is the NSF repository of sediment cores from the ocean floor surrounding Antarctica, and makes sediment cores available to the entire scientific community, providing the equipment and knowledge necessary for scientists to collect samples for specialized measurements. The sediments provide a record of past climate, ocean circulation, and ice sheet history, and were recovered at great cost using piston cores deployed from research vessels and rotary coring from drilling platforms. The funding supports a curator, an assistant curator, and a student work force from FSU. This staff supports visiting scientists, manages the collections and the equipment used for core characterization and sampling, and maintain data bases. The AMGRF houses a unique collection of sediment cores from the Southern Oceans and has served in this role for the past 50 years. The Antarctic Marine Geology Research Facility (AMGRF) at Florida State University, the NSF repository of Southern Ocean piston- and drill-cores, has been conducting marine geological research and providing numerous services to the Antarctic and Earth Science Community in its present building for the past 50 years. This proposal requests operating funds to (a) continue provide these services, (b) manage archives and databases, (c) complete necessary upgrades of the AMGRF Cold-Room, and (d) continue our education and outreach programs for students and the general public. The AMGRF archives and curates more than 23,000 m of cored sediment (over 7,000 cores) collected by United States Antarctic Program (USAP) vessels. The Facility also archives and curates some 5,500 m of rotary-cored material from international programs such as ANDRILL. The standard core processing services include core splitting, Multi-Sensor Track analyses, core photography, whole-core x-rays, etc., core description publications (macroscopic and microscopic), and core sampling. Facility personnel also provide curatorial support services to field-based projects upon request. Analytical equipment at the AMGRF serves the research needs of Facility personnel (for the generation of detailed core descriptions), NSF Principal Investigators involved with the United States Antarctic Program (USAP), and qualified users from the scientific community in the U.S. and beyond. This equipment provides users of the Facility with the necessary tools to rapidly and objectively analyze the piston cores and drill cores sent to the Facility each year. The AMGRF maintains a core and sample database with the latest map-sample search capabilities that can be accessed through the continuously upgraded Facility website. This searchable database contains basic information about all the cores stored at the facility, as well as information on samples taken from 1964 to the present. In addition to the sediment core archives the AMGRF also keeps archives of ship and deck-logs, a collection of ca. 862,000 microscope slides, and a library of AMGRF related publications. Facility personnel routinely provide tours and lectures for students and the general public.
