Monitoring Atlantic Inflow to the Arctic (MAIA) Project Data Set (2000-2001)

The dataset comprises hydrographic measurements including current velocity, temperature, salinity and sea level data. Results of one iodine experiment are also included. The data were collected in the area of the Faroe Islands, Shetland, the Norwegian Sea and the Barents Sea between May 2000 and November 2001 over a series of 31 cruises using the research vessels Scotia (UK), Magnus Heinason (Faroes), Johan Hjort and G.O.Sars (Norway). Measurements included five repeated conductivity-temperature-depth (CTD) sections in the Faroe Shetland Channel, North of Faroes, Gimsøy and Svinøy and Fugløya - Bear Island. Fifty one moorings containing current meters, acoustic Doppler current profilers (ADCPs), bottom pressure recorders and inverted echosounders were deployed along the sections. Ten RAFOS floats were also deployed in the Lofoten Basin to measure Lagrangian currents. During the Johan Hjort cruise in May 2000 about 300 water samples were collected in order to measure 129Iodine concentration (relative to 127I). Analysis was carried out by the Centre de Spectrométrie Nucléaire et de Spectrométrie de Masse, France. Observational data from the standard tidal stations at Tórshavn, Lerwick, Bodø and Ny-Ålesund were also used in the analysis. The main objective of MAIA was the development of an inexpensive, reliable system for monitoring the inflow of Atlantic water to the northern seas, based on coastal sea-level data. The project involved contributions from a number of international institutions. The resulting data set was collated at BODC and published on CD-ROM in March 2003.

Quality and validity

Lineage: 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. 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: sea level recorders; inverted echosounders; current meters; satellite tracking system; CTD; current profilers.

Conformity

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.
