CTD profile data collected from the Clarion-Clipperton Zone (CCZ), Pacific Ocean during SMARTEX project expeditions JC241 (2023) and JC257 (2024)
Full-depth CTD profiles collected during RRS James Cook cruises JC241 and JC257 in the Clarion-Clipperton Zone (CCZ), northern equatorial Pacific Ocean, an area likely to be targeted for deep-sea mining for polymetallic nodules in 2023 (JC241) and 2024 (JC257). A Sea-Bird 911plus CTD system was used, mounted on a 24-way stainless steel rosette frame, equipped with 12 x 10-litre Niskin bottles. Too few salinity samples were collected for statistics and verification of sensor trends, therefore none were applied. Post-cruise calibration revealed a 0.00193 deg C positive offset of the temp2 (secondary) temperature sensor; this correction was applied in the final files. Scientific objectives: 1. OMCO 1979 experimental site to estimate mining impact on seabed habitats after 40 years; 2. UK-1 site to understand seasonal changes in seafloor currents and benthic boundary layer processes; 3. Mesoscale eddy structure investigation on the approach to UK1. The data were collected by scientists from the National Oceanography Centre, Southampton, UK, as part of the NERC-funded Seabed Mining And Resilience To EXperimental impact (SMARTEX) project (NE/T003537/1).

BODC protocols are based on the Open Archival Information System (OAIS) model enabling BODC to iterate towards compliance with the on-going evolution and development of community requirements including FAIR (Findable,Accessible,Interoperable,Reusable), TRUST (Transparency, Responsibility, User community, Sustainability, Technology) and CARE (Collective Benefit, Authority to Control, Responsibility, Ethics). Data managers quality assure submissions and assemble the metadata necessary for curation. Submissions (as received) are placed in a long-term accession and stored in triplicate across multiple sites. Appropriate data are transferred into a standard internal format with source variable names mapped to controlled vocabularies, documentation assembled, and metadata loaded into BODC databases. Access to these data is through direct request, the BODC website and through partner repositories such as SeaDataNet. Access control is attained by assigning a data policy to each set of data and this policy is used to administer access when data are requested. Discovery metadata is aligned with EU INSPIRE (through MEDIN) and SeaDataNet community standards. Data are converted to open community formats including Ocean Data View ASCII and SeaDataNet NetCDF, with data described using terms from the NERC vocabulary server. BODC submission agreements are documented on the BODC website and customer service is assured with a dedicated requests team that serve data following local regulations including General Data Protection Regulation (GDPR) 2018 and Environmental Information Regulations (EIR) 2004.

This dataset was created by scientists at the Scottish Association for Marine Sciences (SAMS), following their in-house data processing and quality control procedures. The data were provided to the British Oceanographic Data Centre (BODC) for long-term archive and ingestion into the series schema of the National Oceanographic Database (NODB), and subsequently made available via the BODC Published Data Library (PDL).Instrument(s) used to collect data: CTD.
