Overview: The CLIVAR and Carbon Hydrographic Data Office (CCHDO) is the repository, assembly center, and distribution center for full-depth global ocean hydrographic, carbon, and tracer data. These data are a product of several international research programs (the World Ocean circulation experiment (WOCE), the CLImate VARiability and predictability program (CLIVAR), the International Ocean Carbon Coordination Project (IOCCP), the Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP)), and national research programs - past, present and to come. Whenever possible the CCHDO provides these data in three community formats: WHP-Exchange, netCDF, and WOCE. The CCHDO seeks to assure that these data and their associated documentation are prepared and made readily available for immediate research and education uses, and that these data have a long service life. The CCHDO?s primary window to the research community is via its web site http://cchdo.ucsd.edu. The CCHDO maintains ties with designated national data archives like NODC/WDC-A to see that the entirety of its public holdings is formally archived and up to date at the archive.Intellectual Merit: The CCHDO brings together, verifies, and corrects content and format errors in the hydrographic, and tracer data used in large scale ocean carbon, global change, water mass, and circulation studies. The team assembles the data with relevant documentation, and carefully prepares them for dissemination and archive. In addition they work to promote appropriate methodology, community standards, communications, and data compatibility. The CCHDO data are created by over 100 data originators worldwide, sometimes with 5 or more investigators separately contributing to one bottle data file. The CCHDO makes it possible for all data users to cope with the temporal-, content-, and format-related file diversity these different originators engender. The CCHDO brings data together to a common content and readability standard, thereby greatly reducing the difficulties research and education data users encounter. A strong additional advantage is that the documentation associated with the data are collected, reorganized to a common standard (where possible), and preserved with the data.Broader Impacts: The CCHDO enhances research infrastructure, the broad dissemination of results, and the integration of research and education. While the CCHDO does not generate new data, it makes the data better and more usable, thus more far reaching and ultimately more scientifically and socially relevant. Via the CCHDO?s actions, present-day and future US and international users of these CTD, routine hydrography, ocean carbon, and tracer ocean profile data can easily use any of the data files written in the ASCII or netCDF exchange formats. This both reduces the personnel costs to data users to import and use data and also makes these data available to a much wider audience in the research, educational, and broader communities who do not employ data specialists. Moreover, the careful assembly of documentation with the data helps to assure a service lifetime for the data far into the future, contributing to a broad range of future studies of long-term ocean variability. The clean-up of the data and rewriting into accepted data formats also make the data much more straightforward to import into computer models. The CCHDO supports CLIVAR and carbon science programs, and is a data component of a global observing system for the physical climate and carbon dioxide system. The CCHDO is hence part of a larger international effort to monitor the ocean?s response to climate change. The CCHDO puts into play the fundamental concept that data collected belong to the community, and should be available to the community at large.

概述：Clivar and Carbon水文数据办公室（CCHDO）是全深度海洋水文，碳和示踪剂数据的存储库，组装中心和配送中心。这些数据是多个国际研究计划（世界海洋循环实验（WOCE），气候可变性和可预测性计划（CLIVAR），国际海洋碳协调项目（IOCCP），全球海洋船舶水文研究计划（GO-SHIP）以及国家研究计划的产物。 CCHDO只要有可能以三种社区格式提供这些数据：WHP-Exchange，NetCDF和WOCE。 CCHDO试图确保这些数据及其相关的文档已准备好并容易用于立即研究和教育用途，并且这些数据的使用寿命很长。 CCHDO的主要窗口通过其网站http://cchdo.ucsd.edu。 CCHDO与NODC/WDC-A这样的指定国家数据档案保持联系，以确保其全部公共持有量是正式的，并在档案中进行了正式存档和最新。该团队将数据与相关文档组装在一起，并仔细准备它们以进行传播和档案。此外，它们还致力于促进适当的方法论，社区标准，沟通和数据兼容性。 CCHDO数据是由全球100多个数据发起者创建的，有时有5名或更多的研究人员分别为一个瓶数据文件做出贡献。 CCHDO使所有数据用户都可以应对这些不同的发起者会产生的时间，内容和格式相关的文件多样性。 CCHDO将数据融合到了共同的内容和可读性标准中，从而大大减少了研究和教育数据用户遇到的困难。一个强大的优势是，收集了与数据相关的文档，重组为通用标准（可能在可能的情况下），并与数据保存。BRODER的影响：CCHDO增强了研究基础设施，结果的广泛传播以及研究和教育的整合。尽管CCHDO并未生成新数据，但它使数据变得更好，更可用，因此更遥远，最终更科学和社会相关。通过CCHDO的动作，当今和未来的美国以及这些CTD的国际用户，常规水文，海洋碳和Tracer Ocean Profile Data可以轻松使用以ASCII或NETCDF交换格式编写的任何数据文件。这两者都降低了人员向数据用户的成本导入和使用数据，还可以使这些数据在研究，教育和不使用数据专家的更广泛社区中提供给更多的受众。此外，仔细的文档与数据组装有助于确保未来数据的服务寿命，从而促进了长期海洋可变性的广泛研究。清理数据并将其重写为接受的数据格式也使数据更加简单地导入到计算机模型中。 CCHDO支持Clivar和Carbon Science计划，并且是全球观察系统的数据组成部分，用于物理气候和二氧化碳系统。因此，CCHDO是一部分国际努力的一部分，以监测海洋对气候变化的反应。 CCHDO提出了数据收集的基本概念，该概念属于社区，应向整个社区提供。
