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. We anticipate that during the year 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. A continuing goal is to upgrade accessibility to the collection. In the past year LDEO was offered an opportunity to upgrade its collection of analog deep-sea core photographs, dating back to 1947, into digital format for availability on the web. With funds provided by this award we will be able to digitize some 14,000 sheets of core photographs. We are confident this will help researches better select sampling depths. The LDEO core repository is a resource for research and teaching in every field of marine science. This award will also support weekend workshops.

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。我们预计，在本奖项的一年中，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。一个持续的目标是提高藏品的可及性。在过去的一年里，LDEO获得了一个机会，将其可追溯到1947年的模拟深海岩心照片集升级为数字格式，以便在网上获得。利用这一奖项提供的资金，我们将能够将大约14,000张核心照片数字化。我们相信，这将有助于研究人员更好地选择采样深度。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。
