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)的主要职能是汇集、核实和纠正用于大规模海洋碳、全球变化、水团和环流研究的CTD、水文和示踪剂数据中的内容和格式错误。CCHDO的工作人员由数据专家、文件专家、程序员兼分析员和学生研究助理组成，他们将数据与相关文件汇编在一起，并仔细准备分发和存档。此外，它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。这项续约合同将使CCHDO能够在2013年前继续其CLIVAR水文测量、全球海洋碳水文测量以及使用高质量海洋剖面数据的类似项目的职能。CCHDO处理的数据由世界各地的100个数据发起者创建，有时5个或更多的PI单独创建一个瓶子数据文件。CCHDO使所有数据用户能够应对不同创建者产生的与时间、内容和格式相关的文件多样性。CCHDO将数据集中到一个共同的内容和可读性标准，从而极大地减少了研究和教育数据用户遇到的困难。另一个强大的优势是，与数据相关的文档被收集、重新组织到一个共同的标准(在可能的情况下)，并与数据一起保存。CCHDO通过互联网(并应要求以DVD形式)传播数据。它还将其公共资料提供给NODC/WDC-A用于长期存档和进一步分发。广泛的影响：随着CCHDO进行合并、核实、内容和格式更正以及文件编制，现在和未来美国和国际用户使用参考质量的CTD、常规水文、碳和示踪剂海洋剖面数据可以很容易地使用任何以文件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变得更加可靠和负担得起。数据不仅更易于使用，其质量和有用性也大大提高，因为CCHDO仔细地将文件与数据组合在一起，有助于确保数据在遥远的未来的使用寿命，为对海洋长期变异性的广泛研究做出贡献。清理数据并重写为NetCDF格式也使数据更直接地导入计算机模型。这些数据是全球海洋学项目的主要成果，它们的广泛传播增进了对科学和技术的理解。CCHDO支持CLIVAR和碳科学项目，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以及热量和淡水通量的长期趋势。CCHDO发挥了一个基本概念，即收集的数据属于社区，应该向广大社区提供。

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.
