Title

Processed multibeam bathymetry data from the northeast Atlantic (JC215, 2021)

Alternative title(s)

British Oceanographic Data Centre record 1048_JC215_XYZ-GSF

Abstract

Multibeam swath bathymetry data were collected with a hull-mounted Kongsberg EM122 echosounder during RRS James Cook cruise JC215 (Principal Investigator Helen Oldridge) in June/July 2021. The cruise was conducted to carry out geophysical equipment trials off the continental margin to the southwest of the UK. The data were edited using CARIS HIPS software by Tim Henstock and exported as generic sensor format (GSF) files for subsequent gridding by users. The data were also gridded at 100m spacing by Tim Henstock in a WGS84 Mercator projection, and were exported as longitude-latitude-depth triples. Funding was provided by the UK's Natural Environment Research Council (NERC) to National Marine Facilities (NMF) under its National Capability Large Research Infrastructure support.

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 cleaned and exported as general sensor format (GSF) files for subsequent gridding by users. They were also gridded at 100m spacing in a WGS84 Mercator projection, and exported as longitude-latitude-depth triples. Both formats were then provided to the British Oceanographic Data Centre (BODC) for long-term archive and data publication in the BODC Published Data Library.Instrument(s) used to collect data: multi-beam echosounders.

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.
