CCHDO: serving easily accessible, global, high-quality hydrographic data for research, climate monitoring, and education

这笔拨款将允许斯克里普斯海洋研究所的海洋数据服务器（CLIVAR和碳水文数据办公室，或CCHDO）继续运行。该设施向社区提供由全球海洋船舶水文调查计划（GO-SHIP）获得的不同类型的数据，该计划是气候观测系统和全球海洋观测系统的一个组成部分。CCHDO为与研究和教育有关的各种目的提供数据。数据用于评估海洋的状况和健康状况，并用于验证海洋模型。该项目将为本科生和研究生开发学习模块，并将改善海洋信息学。这项活动将继续运作克里普斯海洋学研究所的CLIVAR和碳水文数据办公室。该设施收集、标准化和传播由全球海洋船舶水文调查计划（GO-SHIP）获得的水文、碳和示踪数据，该计划是气候观测系统和全球海洋观测系统的一个组成部分。CCHDO开展与数据可用性相关的5项主要活动：a)研究和教育；B)不同的受众；C)全球气候学；D)气候评估；e)在NOAA存档，以便长期保存。数据用于评估海洋对热量、淡水、碳和营养物质的储存和运输；确定海洋对人为碳和热量的吸收；监测海洋氧气和酸化的变化；评估海洋环流和空气流通。此外，CCHDO数据用于模型启动，校准和验证，以及Argo浮子质量控制。该项目还将利用数据档案为本科生和研究生开发学习模块。最后，CCHDO将通过开源软件和共同学习的数据集群来改善海洋信息学。该项目由地球科学理事会共同资助，旨在支持人工智能/机器学习在地球科学领域的发展。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This grant will allow continued operation of an oceanographic data server (the CLIVAR and Carbon Hydrographic Data Office, or CCHDO) at Scripps Institution of Oceanography. This facility provides to the community different types of data obtained by the Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP), which is a component of the Climate Observing System and the Global Ocean Observing System. The CCHDO makes data available for diverse purposes related to research and education. Data are used to assess the state and health of the ocean and for verification of ocean models. The project will develop learning modules for undergraduate and graduate students and will improve ocean informatics.This activity will continue to operate the CLIVAR and Carbon Hydrographic Data Office (CCHDO) at Scripps Institution of Oceanography. This facility aggregates, standardizes and disseminates hydrographic, carbon, and tracer data obtained by the Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP), which is a component of the Climate Observing System and the Global Ocean Observing System. The CCHDO carries out 5 main activities related to data availability for: a) research and education; b) diverse audiences; c) global climatologies; d) climate assessments; and e) archiving with NOAA for long-term preservation. Data are used to assess the ocean storage and transport of heat, freshwater, carbon and nutrients; to determine the ocean’s uptake of anthropogenic carbon and heat; to monitor changes in ocean oxygen and acidification; and to evaluate ocean circulation and ventilation. Also, CCHDO data are used for model initiation, calibration and validation, as well as for Argo float quality control. The project will also develop learning modules for undergraduate and graduate students using the data archives. Finally, CCHDO will effect improvements to ocean informatics through open source software and data clusters for co-learning. This project is co-funded by the Directorate for Geosciences to support AI/ML advancement in the geosciences.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
