CCHDO: responding to changing expectations in a changing world

The mission of CCHDO is to aggregate and disseminate the highest quality CTD, hydrographic, carbon and tracer data. These data come from vessel-based expeditions repeatedly sampling the same cruise tracks and are standardized to common formats. CCHDO provides a central access point for 50+ years of these global data, allowing large-scale and long-term research questions to be addressed. With research vessel activities and other field work in flux, CCHDO provides a stable resource for flexibly supporting shore-based science, whether in the lab or at home.

Supported in part by an EarthCube supplement, CCHDO is implementing a set of improvements to address current and future community expectations, increase compliance with standards, and improve FAIR-ness.

Adding schema.org JSON-LD markup on dataset landing pages to facilitate improved discovery through generic search engines and EarthCube's GeoCODES. This was further used to demonstrate a pilot cross-repository discovery capability in collaboration with BCO-DMO.

Moving data storage to the commercial cloud, with additional system components to follow, in order to increase up-time, decrease staff systems administration time, improve security, and enable scalability. Simply keeping aware of, and responding, to changing security requirements had become an increasingly significant time commitment when managing our own hardware.

Providing NetCDF-CF as a data format (in progress) to increase the usability of CCHDO data, particularly across disciplinary boundaries and by modelers.

Developing Jupyter notebooks for internal data processing workflows, to improve efficiency, consistency, and documentation, and to allow them to be more easily shared.

Hosting post-processed data products made from CCHDO data by the scientists seeking a findable and reliable place for their products (and one that publishers approve of)
