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.

Lamont-Doherty Earth天文台（LDEO）在实际的地点数量和空间覆盖范围内存储了大量深海样品。该系列为研究海底沉积物的国家和国际研究人员提供服务。 该系列的总尺寸约为19,000个内核和3,750处疏g，并抓住样品。 在过去的三年中，该系列中的20,000多个样本分发给了75名科学家和85名教师。在过去的五年中，基于该存储库的样本涵盖了与我们当前和过去的气候，其他环境研究以及宇宙影响研究有关的主题的109个出版物。 可以预见，在该奖项期间，存储库将向全球研究界分发约7000个样本，描述和存档500挖泥机/抓取样品，并在冷藏容器中描述和存储并存储100多个活塞核心。持续的目标是将数字可访问性升级到该馆藏的长期可靠服务，管理，公共界面，以进行搜索和浏览示例目录，并确保与NOAA-NGDC等外部系统（例如NOAA-NGDC）的互操作性，并通过将数据库分析并随后可视化到使用LDEEO的信息可视化数据库，从而增强数据挖掘，并将数据挖掘到数据库中。一年的试点项目将对未采样和稀疏采样的核心进行碳酸钙测量，以促进其近期使用，以研究过去和快速气候变化。 LDEO核心存储库是海洋科学每个领域的研究和教学资源。该奖项还将支持周末研讨会。
