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 和碳水道测量数据办公室 (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、水道测量和示踪数据中的内容和格式错误。CCHDO 的工作人员由数据专家、文档专家、程序员分析师和学生研究助理组成，他们将数据与相关文档组合在一起，并仔细准备 它们用于传播和存档。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。该续签合同将使 CCHDO 能够在 2013 年继续其 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项目的职能。CCHDO 处理的数据由全球 100 个数据发起者创建，有时有 5 个或更多 PI 分别贡献一瓶数据 文件。 CCHDO 使所有数据用户能够应对这些不同发起者产生的时间、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中，从而大大减少了研究和教育数据用户遇到的困难。另一个强大的额外优势是，收集与数据相关的文档，将其重新组织为通用标准（如果可能），并与数据一起保存。 CCHDO 通过互联网传播数据（并根据要求提供 DVD）。它还向 NODC/WDC-A 提供其公共持有，以进行长期存档和进一步分发。 更广泛的影响：通过 CCHDO 进行的合并、验证、内容和格式更正以及记录，当前和未来的参考质量 CTD、常规水文学、碳和示踪海洋剖面数据的美国和国际用户可以轻松使用任何数据文件 以有据可查的格式编写。这使得研究和教育数据用户导入和使用数据更加可靠且负担得起。 CCHDO 将文档与数据仔细组合，不仅使数据更易于使用，而且其质量和实用性也得到了极大提高，有助于确保数据在未来的使用寿命，为长期海洋变化的广泛研究做出贡献。数据的清理和重写为 netCDF 格式也使得 数据更容易导入计算机模型。这些数据是全球规模海洋学计划的主要成果，其广泛传播增强了科学和技术的理解。 CCHDO 支持 CLIVAR 和碳科学计划，并且是物理气候/二氧化碳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，这些数据用于帮助量化 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、热量和淡水通量的长期趋势。 CCHDO 贯彻了这样的基本理念：收集的数据属于社区，并且应该向整个社区开放。
