The data were collected by the Napier University School of Life Sciences as part of the Land Ocean Interaction Study (LOIS) Shelf Edge Study (SES).

  • This dataset comprises 45 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in April 1996 from stations in an area, centred around 56.5 N, 9.0 W in the North East Atlantic. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Napier University School of Life Sciences as part of the Land Ocean Interaction Study (LOIS) Shelf Edge Study (SES).

  • The data set contains a variety of physical, chemical and biological parameters. Hydrographic profiles provided temperature, salinity, fluorescence, dissolved oxygen and transmissance measurements, which were supplemented by time series of surface ocean and meteorological properties. Time series of current velocities, temperature and sea level were also collected. Biogeochemical and biological analyses of water samples provided nutrient, phytoplankton and zooplankton data, while production data were derived from incubation experiments. The data were collected at seven stations in the Celtic Sea with varying physical and biological characteristics. Fieldwork was undertaken between 15th and 29th May 2000, with each station being occupied for 24 hours. Data were collected via shipboard deployment of CTD profilers and undulators with accompanying auxiliary sensors, and discrete water sampling. Further data were obtained from three moorings including acoustic Doppler current profilers (ADCPs), temperature recorders and bottom pressure recorders that were also deployed and recovered during the study period. Measurements were collected during RRS Discovery cruise D246 as part of the multidisciplinary study of the interactions between physical processes and biological production in contrasting pelagic shelf waters. An additional goal of the study was to map the tidal front situated in the St George's Channel. The study was co-ordinated by Plymouth Marine Laboratory and the research involved 28 scientists and technicians from 14 separate institutions situated in five different countries. Data are managed by the British Oceanographic Data Centre.

  • This dataset comprises 130 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during March - April 1999 from the region 52.3 N, 4.3 E in the southern North Sea. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Royal Netherlands Institute for Sea Research as part of the PROcesses of Vertical Exchange in Shelf Seas (PROVESS) project.

  • This dataset comprises 166 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in September 1998 from sites centred at 59 20 N, 1 E covering the northern North Sea. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Alfred Wegener Institute for Polar and Marine Research as part of the PROcesses of Vertical Exchange in Shelf Seas (PROVESS) project.

  • The data set comprises hydrographic, biogeochemical and biological data, including measurements of temperature, salinity and attenuance, plus concentrations of parameters such as nutrients, pigments, urea, hydrocarbons, sedimentation flux, sulphur and dissolved carbon. Analyses of bacterial, zooplankton and phytoplankton communities were also undertaken. The oceanographic data were supplemented by measurements of surface meteorological parameters. Data were collected across three repeated sections: one along the Gulf of Oman; a section at 67deg East from 8 to 14.5deg North; and a major section from 8deg North, 67 deg East to the coast of Oman. Other one-off sections were also traversed in the Arabian Sea and Gulf of Oman areas. Measurements were collected during two cruises: one between 27 August and the 4 October 1994 and the other between the 16 November and the 19 December 1994. Sections were covered by underway surface ocean measurements (one minute sampling of multiple parameters providing some 5 million measurements) complemented by a total of 21 CTD/water-bottle stations, 14 of which were repeated. ARABESQUE was organised by the Plymouth Marine Laboratory of NERC's Centre for Coastal and Marine Sciences and involved the University of Wales, Bangor; Queen's University of Belfast; University of East Anglia; University of Edinburgh; University of Newcastle; the Bedford Institute of Oceanography, Canada; the Max Planck Institute for Limnology, Germany and the Sultan Qaboos University, Oman. Data management support for the project was provided by the British Oceanographic Data Centre. All data collected as part of the project were lodged with BODC who had responsibility for assembling, calibrating, quality controlling and fully documenting the data. BODC checked for instrument spikes or malfunction, values beyond the calibration range, unreasonable ratios of chemical constituents and unreasonable deviations from climatological means. Data were assembled into a relational database, complete with supporting documentation and a user manual. The full data set has been published by BODC on CD-ROM complete with user interface.

  • The dataset includes a wide range of physical, chemical and biological oceanographic parameters. Physical hydrographic measurements include temperature, salinity, optical backscatter, current velocities and turbulence, while biogeochemical measurements in the water column include dissolved oxygen, organic carbon and nitrogen, and nutrients. Biogeochemical parameters were also measured in sediment cores, while phytoplankton and zooplankton data were also collected. The marine data were supplemented by meteorological measurements including temperature, pressure, irradiance and wind. The experimental phase of the project was undertaken in the North Sea between 1998 and 1999, and data were collected at two contrasting sites: Northern North Sea (NNS, 59deg 20.0E, 1deg 00.0E) and Southern North Sea (SNS, 52deg 15.0N, 4deg 17.0E). At both locations measurements were concentrated at a central position with additional measurements being made to estimate horizontal gradients. Moored instruments were deployed at NNS from September - November 1998 and at SNS from March - May 1999. Each experiment was supported by intensive measurement series made from oceanographic ships and involving turbulence dissipation profiler, conductivity-temperature-depth (CTD) profilers, particle size profilers, optical profilers, benthic sampling and water bottle sampling. PROVESS is an interdisciplinary study of the vertical fluxes of properties through the water column and the surface and bottom boundary layers with the aim of improving understanding and quantification of vertical exchange processes in the water column. Scientists from 18 institutions distributed in 8 European countries participated in the fieldwork and modelling parts of the programme and was co-ordinated by John Howarth of the Proudman Oceanographic Laboratory. The British Oceanographic Data Centre (BODC) is responsible for assembling the data collected during the project into a comprehensive data set. The data has been organised onto a CD-ROM product available through BODC.

  • The dataset comprises a diverse set of physical, chemical and biological data including: bacteria, carbon, chlorophyll, dissolved gases, light levels, nutrients, phytoplankton, productivity, respiration, salinity, temperature, trace elements and zooplankton. Measurements were gathered from the North Atlantic and Norwegian fjord waters between 1971 and 1998. The data arise from three sources: biological and hydrographic data collected between 1971 and 1975 at Ocean Weather Ship (OWS) India in the North Atlantic; conductivity-temperature-depth (CTD) casts, water samples, net samples and meteorological data from the four week Bergen Mesocosm experiment at Espegrend Marine Biological Field Station (Norway) in 1995; and the six week RRS Discovery cruise 221 to the North East Atlantic in 1996, where physical, chemical and biological data were collected. The data were collected using a variety of methods including: more than 500 CTD and SeaSoar profiles; nearly 1000 water bottle samples; over 600 net hauls; over 450 Secchi disk deployments; nearly 4000 multisizer samples; 23 production experiments; four drifting buoy tracks and 40 days of weather observations. The PRIME programme aimed to lay the basis for mathematical models to describe the role of plankton in biogeochemical fluxes within the oceans which have implications for climate regulation. The project was hosted by the School of Ocean Sciences, University of Wales, Bangor. Data management was undertaken by the British Oceanographic Data Centre and over 95% of the data collected are now assembled on a CD-ROM. The data are accompanied by an extensive users' guide (covering sampling protocol documentation), the structures used to store the data, and the data interrogation tools.
