The LDEO Deep-Sea Sample Repository and the Curating and Maintenance of the Sediment Library and Dredge Collection

拉蒙特-多尔蒂地球观测站（LDEO）从实际站点数量和空间覆盖范围两方面对大量深海样本进行了存档。该收藏品为研究海底沉积物的国家和国际研究人员提供服务。 收集的总规模约为19，000个岩心和3，750个挖泥和抓斗样本。 在过去三年中，收集的20 000多个样本分发给了75名科学家和85名教师。在过去的五年里，有109篇基于该储存库样本的出版物，涵盖了与我们现在和过去的气候，其他环境研究和宇宙影响研究有关的主题。 预计在授标期间，储存库将向全球研究界分发约7000个样本，描述和存档500个挖掘/抓取样本，并描述和储存在冷藏容器中的100多个活塞芯。持续目标是升级馆藏的数字可访问性，以提供长期可靠的服务、管理、公共接口来执行样本目录的搜索和浏览，并确保与NOAA-NGDC等外部系统的互操作性，并通过解析核心来增强数据挖掘。将描述挖掘到数据库中，然后使用LDEO开发的工具将信息可视化。一个为期一年的试点项目将对未取样和稀疏取样的岩心进行碳酸钙测量，以促进其在调查过去和快速气候变化方面的近期使用。LDEO核心存储库是海洋科学各个领域研究和教学的资源。该奖项还将支持周末研讨会。

The Lamont-Doherty Earth Observatory (LDEO) archives a large collection of deep-sea samples, both in actual number of sites and in spatial coverage. The collection provides a service to national and international researchers who study ocean floor sediments. Total size of the collection is ~19,000 cores and 3,750 dredges and grab samples. During the past three-years over 20,000 samples from the collection were distributed to 75 scientists and 85 teachers. During the last five years there have been 109 publications based upon samples from this repository that cover topics related to our present and past climate, other environmental studies, and studies of cosmic impacts. It is anticipated that during the period of this award, the repository will distribute some 7000 samples to the global research community, describe and archive 500 dredge/grab samples, and describe and store, in refrigerated containers, over 100 piston cores. Continuing goals are to upgrade digital accessibility to the collection for long-term reliable service, administration, a public interface to carry out searching and browsing of the sample catalog and assured interoperability with external systems such as NOAA-NGDC and to enhance data mining by parsing core and dredge descriptions into the database and subsequently visualizing the information using tools developed at LDEO. A one year pilot project will conduct calcium carbonate measurements on un-sampled and sparsely-sampled cores to promote their near-term use for investigations of past and rapid climate change. The LDEO core repository is a resource for research and teaching in every field of marine science. This award will also support weekend workshops.
