Operation of the CLIVAR & Carbon Hydrographic Data Office at UCSD/SIO

智力价值：大规模海洋环流研究中使用的水文、营养和示踪数据将被汇集、核实、纠正内容和格式错误，与相关文件汇编在一起，并仔细准备在CLIVAR(气候变异性和可预测性计划)和碳水文数据办公室(CCHDO)传播和存档。此外，CCHDO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。CCHDO处理的这类数据是由全球100个数据发起者创建的，有时5个或更多人参与一个文件。所有数据用户都必须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。使数据集符合共同的内容和可读性标准的巨大优势仍然是继续支持现有数据办公室的最有力的论据，此外还有一个强大的优势，即收集与数据有关的文件，按照共同标准重新组织(在可能的情况下)，并与数据一起保存。虽然数据办公室通过互联网、CD-ROM和数据DVD传播数据，但它向指定的国家档案馆提供包括文件在内的全部公共资料，并进一步分发。广泛的影响：随着拟议的数据办公室进行合并、核实、内容和格式更正以及文件，现在和未来美国和国际用户的参考质量CTD、常规水文测量和示踪器海洋剖面数据可以直接使用任何以常用交换格式编写的数据文件，只要他们可以很容易地读取这样的文件。这既极大地降低了数据用户导入和使用数据的人员成本，也使不雇用数据专家的更广泛的受众能够获得这些数据。此外，文件与数据的仔细组合有助于确保数据在遥远的未来的使用寿命，从而有助于对海洋的长期可变性进行广泛的研究。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。

ABSTRACTOCE-0327555Intellectual Merit: Hydrographic, nutrient and tracer data used in large scale ocean circulation studies will be brought together, verified, corrected for content and format errors, assembled with relevant documentation, and carefully prepared for dissemination and archive at the CLIVAR (CLImate VARiability and Predictability Program) & Carbon Hydrographic Data Office (CCHDO). In addition the CCHDO works to promote appropriate methodology, applicable community standards, communications, and data compatibility.Data of the type dealt with by the CCHDO are created by 100 data originators worldwide, sometimes 5 or more contributing to one file. All data users must cope with the temporal-, content-, and format-related file diversity these different originators engender. It is the enormous advantage of bringing data sets together to a common content and readability standard that remains the strongest argument for continuing support for the present data office, with a strong additional advantage that the documentation associated with the data are collected, reorganized to a common standard (where possible), and preserved with the data. Although the data office disseminates data via the internet, on CD-ROMs and data DVDs, it provides its total public holdings, including documentation, to the designated national archive and further distribution.Broader Impacts: With the merging, verification, content and format correction, and documentation carried out by the proposed data office, present-day and future US and international users of reference-quality CTD, routine hydrography, and tracer ocean profile data can literally use any of the data files written in commonly used exchange formats once they can easily read one such file. This both hugely reduces the personnel costs to data users to import and use data and also makes these data available to a much wider audience 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 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.
