The primary function of the CLIVAR and Carbon Hydrographic Data Office (CCHDO is to bring together, verify, and correct content and format errors in the CTD, hydrographic, and tracer data used in large scale ocean carbon, global change, water mass, and circulation studies. The staff of the CCHDO consists of a team of data experts, documentation specialists, programmer-analysts, and student research assistants who assembles the data with relevant documentation, and carefully prepares them for dissemination and archive. In addition they work to promote appropriate methodology, applicable community standards, communications, and data compatibility. This renewal award will enable the CCHDO to continue its functions for CLIVAR hydrography, global ocean carbon hydrography, and similar programs which use high quality ocean profile data through 2013. The data handled with by the CCHDO are created by 100 data originators worldwide, sometimes with 5 or more PIs 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. The CCHDO disseminates data via the internet (and on request on DVD). It also provides its public holdings to NODC/WDC-A for long-term archive and further distribution.Broader Impacts: With the merging, verification, content and format correction, and documentation carried out by the CCHDO, present-day and future US and international users of reference-quality CTD, routine hydrography, carbon, and tracer ocean profile data can easily use any of the data files written in the well documentated formats. This makes it much more reliable and affordable for research and education data users to import and use the data. Not only are the data easier to use, their quality and usefulness is much improved by the CCHDO's careful assembly of documentation with the data, helping to assure a service lifetime for the data far into the future, contributing to a broad range of studies of long-term ocean variability. The clean-up of the data and rewriting into netCDF formats also make the data much more straightforward to import into computer models. The data are a primary result of global-scale oceanography programs, and their broad dissemination enhances scientific and technological understanding. The CCHDO supports CLIVAR and carbon science programs, and is a data component of a global observing system for the physical climate/CO2 system. The CCHDO is hence part of a larger international effort to monitor the ocean's response to climate change. For example, these data are used to help quantify the uptake and storage of anthropogenic CO2 by the ocean. The data are used to document long term trends in ocean warming, and heat and freshwater fluxes. The CCHDO puts into play the fundamental concept that data collected belong to the community, and should be available to the community at large.

CLIVAR和碳水文数据办公室（CCHDO）的主要职能是汇集、验证和纠正大规模海洋碳、全球变化、水团和环流研究中使用的CTD、水文和示踪数据中的内容和格式错误。CCHDO的工作人员包括一个数据专家，文件专家，程序员分析员和学生研究助理的团队，他们将数据与相关文件组合在一起，并仔细准备分发和存档。此外，他们还致力于推广适当的方法、适用的社区标准、通信和数据兼容性。这一续约合同将使CCHDO能够在2013年之前继续其CLIVAR水文学、全球海洋碳水文学和使用高质量海洋剖面数据的类似计划的职能。CCHDO处理的数据由全球100个数据源创建，有时5个或更多PI单独贡献一个瓶数据文件。CCHDO使所有数据用户能够科普这些不同来源产生的时间，内容和格式相关的文件多样性。CCHDO将数据汇集到一个共同的内容和可读性标准，从而大大减少了研究和教育数据用户遇到的困难。一个很强的额外优势是，与数据相关的文档被收集，重新组织为通用标准（在可能的情况下），并与数据一起保存。CCHDO通过互联网传播数据（并应要求在DVD上）。更广泛的影响：随着CCHDO进行的合并、验证、内容和格式校正以及文档编制，现在和未来的美国和国际参考质量CTD、常规水文学、碳和示踪剂海洋剖面数据的用户可以很容易地使用任何以良好文档格式编写的数据文件。这使得研究和教育数据用户导入和使用数据更加可靠和负担得起。这些数据不仅更易于使用，而且由于CCHDO将文件与数据仔细汇编在一起，其质量和有用性大大提高，有助于确保数据的使用寿命到遥远的未来，有助于对长期海洋变化的广泛研究。清理数据并将其重写为netCDF格式也使数据更容易导入计算机模型。这些数据是全球规模海洋学方案的主要成果，其广泛传播增强了科学和技术理解。CCHDO支持CLIVAR和碳科学计划，是物理气候/CO2系统全球观测系统的数据组成部分。因此，CCHDO是监测海洋对气候变化反应的更大国际努力的一部分。例如，这些数据被用来帮助量化海洋对人为二氧化碳的吸收和储存。这些数据用于记录海洋变暖以及热量和淡水通量的长期趋势。民政事务专员办事处贯彻一个基本概念，就是所收集的数据属于社会，并应供社会大众查阅。
