Lamont-Doherty Core Repository

The Lamont-Doherty Core Repository (LDCR) contains one of the world’s most unique and important collection of scientific samples from the deep sea. Sediment cores from every major ocean and sea are archived at the Core Repository. The collection contains approximately 72,000 meters of core composed of 9,700 piston cores; 7,000 trigger weight cores; and 2,000 other cores such as box, kasten, and large diameter gravity cores. We also hold 4,000 dredge and grab samples, including a large collection of manganese nodules, many of which were recovered by submersibles. Over 100,000 residues are stored and are available for sampling where core material is expended. In addition to physical samples, a database of the Lamont core collection has been maintained for nearly 50 years and contains information on the geographic location of each collection site, core length, mineralogy and paleontology, lithology, and structure, and more recently, the full text of megascopic descriptions.

拉蒙特-多西地质研究所核心库（LDCR）藏有全球最为独特且重要的深海科学样品集合之一。该库中保存了来自各个主要海洋和大洋的沉积岩心，总计约72,000米，包括9,700个活塞岩心；7,000个触发重量岩心；以及2,000个其他类型的岩心，如箱式、卡斯滕式和大型直径重力岩心。此外，我们还拥有4,000个疏浚和抓取样品，其中包括大量锰结核，其中许多由潜水器回收。超过10万份残留物被储存，并在岩心材料耗尽时可供采样。除了物理样品外，拉蒙特核心库的数据库已维持近50年，其中包含每个采集地点的地理位置、岩心长度、矿物学和古生物学、岩石学以及结构等信息，以及最近的全景描述全文。
