  • The dataset comprises 129 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the Celtic Sea area specifically on the shelf edge during July and August 2005. 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 Proudman Oceanographic Laboratory as part of the Seasonal Thermocline Production Control project.

  • This dataset comprises measurements of primary productivity, nutrient, optics and water column structure data (including turbulence information) collected from the Celtic Sea and nearby shelf-edge during 25 July to 14 August 2003 and 15 July to 06 August 2005. Compatible, high-resolution vertical profiles of physical, chemical, and biological parameters were obtained. These were collected by deployments of a conductivity-temperature-depth (CTD) sensor package, a Fast Light Yo-yo (FLY) turbulence profiler and SeaSoar profiler sections, thus allowing quantification of vertical fluxes and primary production on tidal and internal wave time scales. During the CTD profiles, water samples were taken and analysed for nutrients, chlorophyll, primary productivity, sediment concentration, coloured dissolved organic matter (CDOM), trace metal concentrations, dissolved oxygen and salinity. Optical profiles were also taken during 2005 using two radiometers; a Biospherical Instruments PRR-600 and a Satlantic MicroPro. In addition, acoustic Doppler current profiler (ADCP) moorings were deployed around the Celtic Sea to measure current and temperature profiles. The main aim was to investigate the generation and dissipation of turbulence in the thermocline, and to quantify how the resulting mixing (supplying nutrients and controlling the light experienced by the algae) affects the growth of phytoplankton within the sub-surface chlorophyll maximum. The data were collected by the Proudman Oceanographic Laboratory (now the National Oceanography Centre) and by Bangor University. Data management was provided by the British Oceanographic Data Centre.

  • This dataset comprises 35 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in October 2007 throughout Liverpool Bay. 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 Proudman Oceanographic Laboratory as part of the National Oceanography Centre (formerly the Proudman Oceanographic Laboratory), Liverpool Bay/Irish Sea Coastal Observatory initiative.

  • This dataset comprises 10 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during August 2004 along two lines, one running approximately southwest from the Grand Banks, and a second running approximately southeast on the continental slope in front of Nova Scotia. 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 Proudman Oceanographic Laboratory as part of the Rapid Climate Change programme.

  • This dataset comprises 35 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in February 2007 throughout Liverpool Bay. 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 Proudman Oceanographic Laboratory as part of the National Oceanography Centre (formerly the Proudman Oceanographic Laboratory), Liverpool Bay/Irish Sea Coastal Observatory initiative.

  • The data set comprises time series measurements from offshore pressure gauges mounted on the sea floor. The data holdings are approximately 250 observation months from 100 sites. The data have mainly been collected in the continental shelf seas around the British Isles. Data records contain date/time, total pressure and, occasionally, temperature. The sampling interval is typically 15 minutes or hourly, over deployment periods ranging from 1 to 6 months. Data were collected mainly by the Proudman Oceanographic Laboratory (POL), now the National Oceanography Centre (NOC) at Liverpool, and are managed by the British Oceanographic Data Centre (BODC).

  • This dataset comprises 89 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in March 2009 from 2 sites over 19 and 25 hour tidal cycles, in Welsh and Hilbre Channels of the Dee Estuary. 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 Proudman Oceanographic Laboratory as part of the Proudman Oceanographic Laboratory Dee Experiment.

  • This dataset comprises 37 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in June 2007 throughout Liverpool Bay. 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 Proudman Oceanographic Laboratory as part of the National Oceanography Centre (formerly the Proudman Oceanographic Laboratory), Liverpool Bay/Irish Sea Coastal Observatory initiative.

  • This dataset comprises 93 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in December 1995 from stations along the Hebridean slope, 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 Dunstaffnage Marine Laboratory as part of the Land Ocean Interaction Study (LOIS) Shelf Edge Study (SES).

  • This dataset consists of eastward and northward current components at 32 depth levels. The dataset is a gridded dataset, with grid resolution of 1.85 km. It covers the entire Irish Sea area, with a precise range from -2.7 degrees longitude to -7 degrees longitude and from 51 degrees latitude to 56 degrees latitude. The data are daily averages and cover the period from 01 January 1996 to 01 January 2007. The dataset was generated by the Proudman Oceanographic Laboratory Coastal Ocean Modelling System coupled with the Wave Modelling model (POLCOMS-WAM) as part of the Natural Environment Research Council (NERC) CoFEE project which ran from April 2007 to September 2010. The eastward and northward current components were used as input conditions into a coastal processes and sediment transport model which looked at the response of the north Liverpool coastline to extreme flooding events. The dataset was generated by the Proudman Oceanographic Laboratory (since April 2010, part of the UK National Oceanography Centre). The dataset consists of 132 data files in Climate and Forecast (CF) compliant NetCDF format.
