This dataset comprises 137 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in May 1995 from the Hebrides shelf edge and slope east of the Hebrides terrace seamount, 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 University of Wales, Bangor School of Ocean Sciences as part of the Land Ocean Interaction Study (LOIS) Shelf Edge Study (SES).

This dataset comprises 87 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in July 1996 from stations along the Hebridean Shelf and shelf edge west of Scotland, centred around 56 30 N, 9W 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 University of Wales, Bangor School of Ocean Sciences as part of the Land Ocean Interaction Study (LOIS) Shelf Edge Study (SES).

The data set includes hydrographic profiles (including temperature, salinity, attenuance, chlorophyll, oxygen, irradiance, turbulence, sound velocity and currents), hydrographic time series (temperature, currents, fluorescence, bottom pressure), water samples (>70 parameters measured), sediment samples (>160 parameters measured), sediment trap samples (>10 parameters measured), production experiments and marine snow camera profiles. Additional meteorological and wave records are also available, as well as satellite imagery and underwater photography (water column and seabed). The data were collected on the Hebridean Slope (NW of Ireland) between March 1995 and September 1996. Measurements were collected via a combination of shipboard instrument deployments, including >1,800 conductivity-temperature-depth (CTD) and SeaSoar (undulating oceanographic recorder) profiles, >100 expendable bathythermograph (XBT) profiles, >38,000 acoustic Doppler current profiler (ADCP) profiles, >35 core profiles, >800 turbulence profiles, >40 marine snow camera profiles, >55 radiometer profiles and >25 sound velocity and travel time experiments. Benthic lander deployments were also undertaken, along with shipboard incubation experiments and drifting buoy deployments (48 tracks). An intensive water sampling programme provided >2,500 samples for biological and biogeochemical analysis. An extensive moored instrument array was maintained throughout the experiment, including sediment traps, recording current meters (104 series), electromagnetic current meters (9 series), ADCPs (16 series), thermistor chain and temperature probes (70 series), fluorometers (18 series), transmissometers (16 series), light meter (5 series), bottom pressure recorders (11 series), plus one waverider buoy series and three meteorological buoy time series. The Shelf Edge Study (SES) was an intensive multidisciplinary experiment and formed part of the NERC Land Ocean Interaction Study. The British Oceanographic Data Centre (BODC) assembled over 95% of the data sets collected during SES into its project database system. Once basic quality control procedures had been completed the data set was published, complete with extensive data documentation, on CD-ROM.

The dataset contains physical, biological and chemical oceanographic measurements, and meteorological data. Hydrographic measurements include temperature, salinity, attenuance and backscatter, pH and dissolved oxygen concentrations, while water samples were analysed for concentrations of carbon, nitrogen, hydrocarbons, nutrients and pigments. Samples were also collected for phytoplankton and zooplankton analyses, while results from production experiments are also included in the data set. These oceanographic data are supplemented by surface meteorological measurements. Measurements were taken at sites in the Bellinghausen Sea as part of a 2-ship Eulerian experiment between the 28th of October and the 17th of December 1992. The data were collected via (i) underway sampling (SeaSoar Undulating Oceanographic Recorder (UOR), lightfish, hull-mounted acoustic Doppler current profiler (ADCP), meteorology and surface ocean parameters) of which there are 121179 records and (ii) discrete sampling (conductivity-temperature-depth (CTD) and expendable bathythermograph (XBT) casts, bottle stations, net hauls, productivity incubations) of which there are over 1000 deployments and experiments. The study aimed to measure the magnitude and variability of carbon and nitrogen fluxes during early summer in the Southern Ocean, with particular emphasis on rates and processes in the marginal ice zone. The data were collected and supplied by UK participants in the Joint Global Ocean Flux Study (JGOFS). The British Oceanographic Data Centre (BODC) are responsible for calibrating, processing, quality controlling and documenting the data and assembling the final data set. Underway data are stored as 1 minute interval time series for each cruise with all parameters merged on date/time. The data are fully quality controlled; checks were made for instrument malfunction, fouling, constancy, spikes, spurious values, calibration errors, baseline and salt-water corrections. The discrete data are stored in a relational database (Oracle RDBMS), chiefly as vertical profiles and are uniquely identified by a combination of deployment number and depth.
