Process study dataset from cruise JC025 in the Celtic Sea (July 2008) as part of project 'Horizontal patchiness in vertical mixing in stratified shelf seas'

This dataset consists of a variety of hydrographic, biogeochemical and meteorological data. Hydrographic profiles, towed and underway measurements and point sources provided information on free-fall turbulence data, current velocities and acoustic backscatter, water column structure including temperature and salinity, the underwater light field, fluorescence and dissolved oxygen. A comprehensive biogeochemical water sampling programme provided details on nutrients, primary productivity, dissolved organic matter and phytoplankton pigments. Biological samples such as zooplankton were obtained from the water column using nets, and from the sea-bed using grabs. Bathymetry and meteorological parameters were measured across the study area. A dye release experiment was also carried out. Data collection was undertaken in the Celtic Sea. The data were collected during the period 02 - 27 July 2008 during RRS James Cook cruise JC025. Measurements were taken using a variety of instrumentation, including conductivity-temperature-depth (CTD) profilers with attached auxiliary sensors, bathymetric echosounders, water bottle samplers, nets, acoustic Doppler current profilers (ADCPs), remote access water samplers, towed undulators, free-fall turbulence profilers, temperature loggers, fluorometers, grabs and ship flow-through and meteorological packages. The data have been collected as part of the United Kingdom (UK) Natural Environment Research Council (NERC) Oceans 2025 programme (Work Package 3.2) to provide information on vertical mixing processes at the thermocline. This will help improve modelling of these processes and is an expansion of work carried out during a previous National Oceanography Centre Liverpool (NOCL) project ‘Physical-Biological Control of New Production within the Seasonal Thermocline’. The cruise was undertaken jointly by NOCL, the Scottish Association for Marine Sciences (SAMS), the University of Aberdeen, the University of Strathclyde, Napier University and the Joint Nature Conservation Committee (JNCC). The Principal Scientist during the research cruise was Professor Jonathan Sharples of NOCL, who is also the Principal Investigator of Work Package 3.2. CTD data, towed undulator data, temperature logger data, nutrient data, ADCP data, dye tracking data, zooplankton data, primary productivity data and ship underway monitoring system data from this cruise are held at the British Oceanographic Data Centre. Other data have not yet been supplied.

COMMISSION REGULATION (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services

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 taken in the Celtic Sea region to improve knowledge of processes involved in vertical mixing in shelf seas. Water samples and other biological samples were taken by the originators using nets, bed grabs and from CTD bottles. The originators lowered CTD and free-fall turbulence profilers and towed undulators and temperature logger chains from the RRS James Cook. They also deployed moorings containing ADCPs, temperature loggers, fluorometers and underwater cameras on the sea-bed and throughout the water column at sites around the Celtic Sea.

The originators provided full details on data processing and data quality to BODC when submitting their data. BODC then ingested the data, undertaking further quality control and processing appropriate to each data type. 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: fluorometers; current profilers; lowered current profilers; radiometers; CTD undulators; thermosalinographs; underwater cameras; plankton nets; sediment grabs; observers; Fish-finder echosounders; Global Navigation Satellite System receivers; CTD; transmissometers; discrete water samplers; water temperature sensor; dissolved gas sensors; meteorological packages.
