Continuing Operations Proposal: The United States Polar Rock Repository as a Research Tool for Understanding Antarctica's Geological Evolution

极地地区的地质实地考察在后勤上很困难，财政上很昂贵，并且可能对原始地区产生重大的环境影响。 南极洲98%被冰覆盖，裸露的岩石露头稀少，这使得以前收集的岩石样本对科学界非常有价值。2003年在俄亥俄州州立大学建立了美国极地岩石储存库（PRR），以满足保存极地地区岩石、疏浚物和陆地岩心样本的需要。PRR主要从南极洲和南大洋收集地质样品，并通过机构和科学家的捐赠获得这些收藏品。 PRR的存在允许以高昂的财务成本收集的样本被用于充分的科学潜力。目前，超过40，000个样品可作为研究，教育和博物馆展览的免费贷款。 除了物理样品外，PRR还将收集者提供的支持材料存档，例如样品图像、现场地图、航空照片、薄切片以及任何相关的参考书目/DOI。 科学家、研究生和本科生经常使用PRR的样本进行研究项目。 PRR还免费贷款一个教育'岩石盒'，其中包含代表性的岩石，化石和矿物样本，书籍和有关地质学和南极洲的活动，以K-12教师来自美国各地。PRR提供极地岩石样品收集和元数据的管理。它是为数不多的允许对样本使用破坏性研究技术的出借岩石储存库之一。项目执行情况报告网站和内部数字元数据档案为全球传播数据提供了条件，也为试点研究、提案编制和外地后勤规划提供了独特的资源。PRR履行南极研究科学委员会（SCAR）南极数据管理（2009）指令，提供免费、全面和开放的元数据和集合访问权限。在接下来的5年里，PRR将积极与研究界合作，以获得具有科学价值的岩石收藏和补充材料，这将增强PRR的收藏。样本将按照标准的策展实践进行编目，并通过伯德极地气候和研究中心开发的藏品管理系统的面向公众部分进行分类。保存这些实物样本，沿着相关元数据的存档，并纳入DOI？在一个可扩展的在线数据库中，允许在极地地球科学研究中的透明度和再现性。将继续更新和改进收款管理系统。 策展人将继续通过参加会议，创建网络研讨会和联系科学家了解该设施的新藏品来推进PRR的可重复性。PRR将继续履行样品贷款，并加强与其他储存库和数据管理实体的联系，以更好地实现跨学科研究。教育推广到K-12学校将继续与'极地摇滚盒'是免费提供给美国学校。

Geological field expeditions in polar regions are logistically difficult, financially expensive, and can have a significant environmental impact on pristine regions.  The scarcity of exposed rock outcrop in Antarctica, which is 98% ice-covered, makes previously collected rock samples very valuable to the science community. The U.S. Polar Rock Repository (PRR) was established at the Ohio State University in 2003 to meet the need for preserving rock, dredge, and terrestrial core samples from polar areas. The PRR curates geological samples collected primarily from Antarctica and the southern oceans and acquires these collections through donations from institutions and scientists. The existence of the PRR allows samples collected at a high financial cost to be used to their full scientific potential. Currently more than 40,000 samples are available as no-cost loans for research, education, and museum exhibits. In addition to the physical samples, the PRR archives supporting materials from the collector, such as images of the samples, field maps, air photos, thin sections, and any associated bibliography/DOIs. Scientists, graduate students, and undergraduate students routinely use samples from the PRR for their research projects. The PRR also freely loans an educational 'rock box' that contains representative rock, fossil and mineral samples, books and activities about geology and Antarctica to K-12 teachers from across the United States. The PRR provides stewardship of polar rock sample collections and metadata. It is one of the few lending rock repositories to allow destructive research techniques to be used on samples. The PRR website and in-house digital metadata archive provides for global dissemination of data and also a unique resource for pilot studies, proposal preparation and field logistics planning. The PRR fulfills the Scientific Committee on Antarctic Research (SCAR), Antarctic Data Management (2009) directive of providing free, full and open access to metadata and collections. Over the course of the next 5 years, the PRR will work proactively with the research community to acquire scientifically valuable rock collections and supplementary materials that will enhance the PRR collection. Samples will be cataloged following standard curatorial practices and will be made discoverable through the public facing portion of the Collections Management system developed at the Byrd Polar Climate and Research Center. The preservation of these physical samples, along with archiving of associated metadata, and inclusion of DOI?s in a discoverable online database, allows for transparency and reproducibility in polar earth science research. The Collections Management System will continue to be updated and improved. The Curator will continue to advance the discoverability of the PRR by attending meetings, creating a webinar and contacting scientists about new collections at the facility. The PRR will continue to fulfill loans of samples and enhance the links with other respositories and data management entities to better enable interdisciplinary research. Educational outreach to K-12 schools will continue with the 'polar rock box' being freely available to US schools.
