CTD, XBT, XCTD and thermistor chain data collected during the Geophysical Oceanography project which ran from February 2006 to September 2009

This dataset contains a variety of hydrographic measurements including temperature, salinity, sound velocity, current speed/ direction and seismic data. Hydrographic profilers provided measurements of temperature, salinity, sound velocity and density. Four mooring stations were also installed as part of this project, with three minilogger chains providing temperature data and four moored ADCPs measuring current veloicty. The project ran from February 2006 to September 2009, however all of the data were collected between 17 April 2007 and 14 May 2007 during two cruises which took place in the Gulf of Cadiz. The research was conducted using two research vessels, the RRS Discovery (cruise D318) and the RV Poseidon (cruise PO350). The RRS Discovery cruise D318 was split into two legs, D318a, which took place between 17 April 2007 and 23 April 2007 and D318b, which took place between 29 April 2007 and 14 May 2007. For the second leg of cruise D318, the RRS Discovery was joined by the RV Poseidon. Hydrographic measurements were taken using a variety of instruments, including expendable bathythermographs (XBT), expendable CTDs (XCTD), conductivity-temperature depth (CTD) profilers, acoustic doppler current profilers (ADCP) and VEMCO minilogger chains. Airguns and streamers were used in the recording of the seismic data. The main objectives of the Geophysical Oceanography (GO) project were A) To evaluate and improve new research methods in the developing field of seismic oceanography by exploiting the opportunity of two-ship operations between RSS Discovery and RV Poseidon and B) To study the internal wave field and mixing processes in the Gulf of Cadiz and demonstrate quantitative links between seismic and oceanographic measurements. The cruise was coordinated by Durham Univerity and funded under an EU grant as part of the Framework 6 NEST programme. Eight scientific institutions were involved in the project. These were: the University of Durham, the Proudman Oceanographic Laboratory (POL), the Helmholtz Centre for Ocean Research Kiel (IFM-GEOMAR), the French Research Institute for Exploitation of the Sea (IFREMER), the Italian National Agency for New Technologies, the Energy and Sustainable Economic Development (ENEA), the Spanish National Research Council (CSIC), the University of Western Brittany and the University of Lisbon. Data from the programme 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

Data were recorded in the Gulf of Cadiz in April and May 2007 in order to study the internal wave field and mixing processes in the Gulf and to test and improve research methods in seismic oceanography. Hydrographic measurements were made using expendable bathythermographs (XBTs), expendable CTDs (XCTDs) CTD profiles and lowered ADCPs, ADCP moorings and temperature logger mooring chains. Seismic data were also recorded using airguns and streamers. All measurements were made using the RRS Discovery.

The originators supplied the hydrographic data in processed form to BODC for ingestion, along with details on their processing methodologies and quality control procedures. The seismic data were not processed and were supplied in their raw format.

BODC will ingest the data (seismic data excepted) 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 a full 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: bathythermographs; CTD; thermistor chains.
