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困难，在财政上昂贵，并且可能对原始地区产生重大的环境影响。在98%被冰覆盖的南极洲，裸露的岩石很少，这使得之前收集的岩石样本对科学界非常有价值。美国极地岩石储存库（PRR）于2003年在俄亥俄州立大学建立，以满足保存极地岩石、疏浚和陆地岩心样本的需求。PRR管理主要从南极洲和南大洋收集的地质样本，并通过机构和科学家的捐赠获得这些样本。PRR的存在使以高昂的财政成本收集的样本得以充分发挥其科学潜力。目前有4万多件样品可以免费借阅，用于研究、教育和博物馆展览。除了实物样本外，PRR还将收集者提供的辅助材料存档，如样本图像、野外地图、航空照片、薄片和任何相关的参考书目/ doi。科学家、研究生和本科生经常在他们的研究项目中使用PRR的样本。PRR还免费借给来自美国各地的K-12教师一个教育“岩石盒”，里面有代表性的岩石、化石和矿物样本、有关地质学和南极洲的书籍和活动。PRR提供极地岩石样本收集和元数据的管理。它是少数几个允许对样本使用破坏性研究技术的借出岩石库之一。PRR网站和内部数字元数据档案提供全球数据传播，也是试点研究、提案编制和实地后勤规划的独特资源。PRR履行南极研究科学委员会（SCAR），南极数据管理（2009）的指令，提供免费，全面和开放的元数据和收集。在接下来的5年中，PRR将积极与研究界合作，以获得具有科学价值的岩石收藏品和补充材料，以加强PRR的收藏。样本将按照标准的策展实践进行编目，并将通过伯德极地气候与研究中心开发的藏品管理系统的面向公众的部分进行发现。这些物理样本的保存，以及相关元数据的归档，以及DOI？S在一个可发现的在线数据库中，允许极地地球科学研究的透明度和可重复性。收款管理系统会继续更新和改善。馆长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的发现。PRR将继续提供样品，并加强与其他主管部门和数据管理实体的联系，以便更好地进行跨学科研究。美国将继续向K-12学校提供免费的“极地岩石盒”。

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.
