The study area is located within the Antarctic Circumpolar Current (ACC) in the southeast Pacific, Drake Passage and Scotia Sea regions of the Southern Ocean. Data collection began in December 2009 and ended in April 2014. The data were collected via a combination of research cruises in the southern hemisphere summer seasons. Three cruises were intended (UKD-1, UKD-2 and UKD-3) a further three cruises were completed (UKD-2.5, UKD-4 and UKD-5). Shipboard data collection involved the deployment of conductivity-temperature-depth (CTD) packages, accompanied by lowered acoustic Doppler current profilers (LADCPs), and Vertical Microstructure Profilers (VMPs) in a grid pattern across the study area. Continuous measurements of current velocities (using vessel mounted ADCPs, VMADCPs), bathymetry and surface ocean and meteorological properties were collected throughout each cruise. An inert chemical tracer (sulphur hexafluoride, SF6) was released into the ACC in early 2009, and subsequent cruises measured temporal changes in the tracer distribution via the analysis of water samples collected at CTD stations. In addition, a mooring cluster was deployed in Drake Passage in early 2009 provided approximately two years' worth of hydrographic time series data. Floats and drifters were also deployed in the 2009 and 2010 seasons. The DIMES project aims to enhance understanding of mixing processes in the Southern Ocean, as it is thought that such processes may significantly affect ocean energetics and property balances, and thus have implications for the accuracy of climate models. DIMES brings together researchers from both UK and US institutions, including the National Oceanography Centre (NOC), the University of East Anglia (UEA), British Antarctic Survey (BAS), the Scottish Association for Marine Science (SAMS), Woods Hole Oceanographic Institution (WHOI), Scripps Institute of Oceanography, Florida State University, the University of Washington and Massachusetts Institute of Technology (MIT). The UK principal investigator (PI) is A. Naveira Garabato from NOC and the UK data will be managed by the British Oceanographic Data Centre (BODC). Data collected on US cruises, including all float and drifter data, will be managed by US institutions and are not held at BODC.

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. true This dataset was created by the organisations with the "originator" role in this metadata record 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.
