CCHDO

The CCHDO provides access to standard, well-described datasets from reference-quality repeat hydrography expeditions. It curates high quality full water column Conductivity-Temperature-Depth (CTD), hydrographic, carbon and tracer data from over 2,500 cruises from ~30 countries. It is the official data center for CTD and water sample profile data from the Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP), as well as for WOCE, US Hydro, and other high quality repeat hydrography lines (e.g. SOCCOM, HOT, BATS, WOCE, CARINA.)

CCHDO（全球海洋综合调查数据集）提供对来自参考质量重复水文测量考察的标准、详尽描述的数据库的访问。该中心精心整理了来自约30个国家的2500多次航次的高质量全水柱电导率-温度-深度（CTD）、水文、碳和示踪数据。它是全球海洋船基水文调查计划（GO-SHIP）中CTD和水样剖面数据的官方数据中心，同时也是世界海洋环流实验（WOCE）、美国水文调查以及其他高质量重复水文测量航线（例如SOCCOM、HOT、BATS、WOCE、CARINA）的数据中心。
