Benthic carbon fixation and cycling in diffuse hydrothermal and background sediments in the Bransfield Strait, Antarctica in 2011
British Oceanographic Data Centre record 1048_NE-J011307-1
This dataset is comprised of carbon isotopic composition and concentration of samples from stable isotope pulse chase tracer experiments. Data are available for sediment macrofauna, dissolved inorganic carbon in overlying water, and phospholipid fatty acids (PLFAs) in the sediment. Experiments were conducted onboard RRS James Cook (JC055) from 13/01/2011 to 22/02/2011 at three sites in the Bransfield Strait, Antarctica. Two of the sites lay on raised edifices, known as Hook Ridge and Middle Sister along the axis of the basin and included a diffuse hydrothermal site. A third site labelled as 'Off-Vent' others without hydrothermal vents was located along the north side of the basin, and was sampled as a control site. Sediment cores were recovered using a multiple corer for isotope tracing experiments. Duplicate cores were subject to two treatments; the 'algae' treatment with added algal detritus (simulating photosynthetic carbon) and the 'bicarbonate' treatment to simulate a substrate for benthic carbon fixation. Overlying water samples were analysed for concentration and isotopic composition of dissolved inorganic carbon. Frozen sediment samples were freeze dried and analysed for phospholipid fatty acids (PLFAs). Sediment horizons between 0 and 10cm preserved in formalin were sieved and macrofauna were extracted. This work was carried out by Clare Woulds, James Bell, and Louise Brown at the University of Leeds, Adrian Glover at the Natural History Museum, and Steven Bouillon at KU Leuven. It was funded by the NERC Discovery Science project Tracer Studies of Biological Carbon Cycling in Chemosynthetic Communities of the Southern Ocean (grant reference NE/J013307/1) active from March 1, 2012 to February 28, 2015.

This dataset was created by scientists for the NERC Discovery Science project titled 'Tracer Studies of Biological Carbon Cycling in Chemosynthetic Communities of the Southern Ocean'(grant reference NE/J013307/1) following their in-house data processing and quality control procedures. The data were then provided to the British Oceanographic Data Centre (BODC) for long-term archive and data publication in the BODC Published Data Library. Some of 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.

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.
