Operation of the CLIVAR and Carbon Hydrographic Data Office at UCSD/SIO, 2009-2013

CLIVAR和碳水文数据办公室（CCHDO）的主要功能是汇集、验证和纠正大尺度海洋碳、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的工作人员由数据专家、文档专家、程序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，并仔细准备它们以供传播和存档。此外，他们还致力于促进适当的方法、适用的社区标准、通信和数据兼容性。该续约合同将使CCHDO在2013年之前继续其CLIVAR水文、全球海洋碳水文和使用高质量海洋剖面数据的类似项目的功能。CCHDO处理的数据由全球100个数据发起者创建，有时有5个或更多的pi单独贡献一个瓶数据文件。CCHDO使所有数据用户能够处理这些不同创建者产生的与时间、内容和格式相关的文件多样性。《数据中心条例》将数据汇集到一个共同的内容和可读性标准，从而大大减少了数据使用者在研究和教育方面遇到的困难。另一个强大的优势是，与数据相关的文档被收集起来，重新组织为公共标准（如果可能），并与数据一起保存。CCHDO通过互联网（或应要求以DVD形式）传播数据。它还将其公共馆藏提供给NODC/WDC-A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、内容和格式校正以及文件编制，现在和未来的美国和国际用户可以轻松使用参考质量的CTD、常规水文、碳和示踪剂海洋剖面数据，可以轻松使用任何以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。这些数据不仅更容易使用，而且由于CCHDO仔细地将文件与数据组合在一起，它们的质量和用途也大大提高，有助于确保这些数据在未来很长一段时间内的使用寿命，有助于对长期海洋变化进行广泛的研究。数据的清理和改写为netCDF格式也使数据更容易导入计算机模型。这些数据是全球尺度海洋学计划的主要成果，它们的广泛传播增强了科学和技术的认识。CCHDO支持CLIVAR和碳科学项目，是全球物理气候/二氧化碳系统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。这些数据被用来记录海洋变暖、热量和淡水通量的长期趋势。CCHDO发挥的基本概念是，收集的数据属于社区，并应提供给整个社区。

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.
