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.

ABSTRACTOCE-0327555智力价值：大规模海洋环流研究中使用的水文、营养物和示踪剂数据将被汇集、验证、纠正内容和格式错误，与相关文件组装在一起，并精心准备在 CLIVAR（气候变化和可预测性计划）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 处理的此类数据由全球 100 个数据发起者创建，有时有 5 个或更多数据发起者贡献一个文件。所有数据用户都必须应对这些不同的创建者所产生的时间、内容和格式相关的文件多样性。将数据集汇集到一个共同的内容和可读性标准的巨大优势仍然是继续支持当前数据办公室的最有力的论据，还有一个强大的额外优势，即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。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档在内的全部公共持有量并进一步分发。 更广泛的影响：通过拟议数据办公室进行的合并、验证、内容和格式更正以及文档记录，当前和未来的参考质量 CTD、常规水文学和示踪海洋剖面数据的美国和国际用户实际上可以使用任何数据 以常用交换格式编写的文件，一旦他们可以轻松读取这样的文件。这既极大地降低了数据用户导入和使用数据的人员成本，又使这些数据可供不雇用数据专家的更广泛的受众使用。此外，将文档与数据仔细组合有助于确保数据在未来的使用寿命，从而有助于对长期海洋变化的广泛研究。数据的清理和重写为 netCDF 格式也使得数据更容易导入到计算机模型中。
