Sustained observations on World Ocean Circulation Experiment sections in the Drake passage (November 1993 - onwards)

The Drake Passage is a hydrographic section, occupied almost annually since 1993, consisting of full-depth CTD stations and lowered and shipboard Acoustic Doppler Current Profiler measurements. It is occupied annually to detect changes in the Antarctic Circumpolar Current (ACC) and variability of the ocean transport. The standard section includes measurements of the physical properties of the ocean, i.e. temperature, salinity and currents. The Drake Passage section lies on a satellite ground track with the northern end on the south side of Burdwood Bank, south of the Falkland Islands, and the southern end off Elephant Island at the tip of the Antarctic Peninsula. The data have been collected in months between November and February, since 1993 (with the exception of 1995/96 and 1998/99). Measurements were taken using conductivity temperature depth (CTD) profilers and Acoustic Doppler Current Profilers (ADCPs). The Drake Passage provides the link between the Pacific and Atlantic Oceans, as it constricts the ACC to a narrow geographical region, which makes this the best place to measure its properties. The Drake Passage is a series of sustained observations which are taken to identify small changes in the ACC. The work was initially led by scientists from the Institute of Oceanographic Sciences at Wormley, and more recently by teams from the National Oceanography Centre at Southampton. The main partners have been from NERC's British Antarctic Survey. Data, from the section, are held at the British Oceanographic Data Centre.

Explanation
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.

Statement

This dataset was created on by NERC scientists from 1993 onwards in the Drake Passage area of the Southern Ocean following their in-house data processing and quality control procedures. The data were then provided to the British Oceanographic Data Centre (BODC) for ingestion into one of the schemas of the National Oceanographic Database (NODB). During ingestion BODC undertake quality control, documentation and metadata enhancement procedures appropriate to the type of data. For an overview please see http://www.bodc.ac.uk/about/information_technology/data_processing_steps/. BODC supply full information about data collection, data processing and data quality with all data requests to enable users to assess data suitability themselves.

Instrument(s) used to collect data: thermosalinographs; CTD.
