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)记录了大量深海样本，包括实际站点数量和空间覆盖范围。该藏品为研究海底沉积物的国内和国际研究人员提供服务。采集物的总规模约为19,000个岩芯和3,750个挖掘船和抓取样本。在过去的三年里，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，根据这个资料库的样本发表了109份出版物，涵盖了与我们现在和过去的气候、其他环境研究以及宇宙影响研究有关的主题。预计在本授标期间，该储存库将向全球研究界分发约7000个样品，描述和存档500个挖掘/抓取样品，并将100多个活塞芯描述和储存在冷藏集装箱中。持续的目标是提高馆藏的数字可访问性，以便提供长期可靠的服务和行政管理，提供一个公共界面，以便对样本目录进行搜索和浏览，并确保与NOAA-NGDC等外部系统的互操作性，并通过将核心描述和疏浚描述解析到数据库中，然后利用LDEO开发的工具将信息可视化，从而加强数据挖掘。一个为期一年的试点项目将对未采样和稀疏采样的岩芯进行碳酸钙测量，以促进其近期用于调查过去和快速的气候变化。LDEO核心资源库是海洋科学各个领域的研究和教学资源。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.
