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.

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。 我们预计，在此奖项的一年中，存储库将向全球研究界分发大约7000个样本，描述和存档500挖泥机/抓取样品，并描述并存储在冷藏的容器中，超过100个活塞核心。一个持续的目标是将可访问性升级到该集合。在过去的一年中，Ldeo提供了一个机会，可以将其可追溯至1947年的模拟深海核心照片收集到数字格式中，以在网络上可用。通过该奖项提供的资金，我们将能够数字化约14,000张核心照片。我们相信这将有助于研究更好地选择采样深度。 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。
