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

知识价值：在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，与相关文件一起汇编，并在CLIVAR（CLImate可变性和可预测性计划）碳水文数据办公室（CCHDO）仔细准备以供传播和存档。此外，CCHDO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。CCHDO处理的这类数据由全球100个数据源创建，有时5个或更多数据源创建一个文件。所有数据用户都必须科普这些不同的原始文件所产生的时间、内容和格式相关的文件多样性。将数据集汇集到一起以达到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理由，还有一个很大的额外优势，即收集与数据有关的文件，重新组织以达到共同的标准（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、光盘和数据DVD传播数据，但它将其全部公共财产，包括文件，提供给指定的国家档案馆和进一步分发。随着合并，验证，内容和格式更正，以及拟议的数据办公室进行的文件，现在和未来的美国和国际用户的参考质量CTD，例行水文，并且示踪剂海洋剖面数据一旦能够容易地读取一个这样的文件，就可以使用以常用交换格式编写的任何数据文件。这不仅大大降低了数据用户导入和使用数据的人力成本，而且还使这些数据可供更广泛的受众使用，而这些受众并不需要雇用数据专家。此外，将文件与数据仔细组合有助于确保数据在遥远的未来仍有使用寿命，有助于对海洋长期变化进行广泛的研究。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。

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.
