  • The data set comprises time series of non-directional surface wave spectra from moored buoys and shipborne wave recorders at fixed locations. Individual spectra comprise some 60 or so estimates of wave energy at a range of spectral frequencies, computed from 20 to 30 minute recordings of the sea surface displacement/heave. The spectra are computed at intervals ranging from 1 to 3 hours. Data holdings comprise 500 recording months of data from some 14 sites across the continental shelf areas around the British Isles and the NE Atlantic between 1976 and 1995. Observation periods at specific sites vary from 4 months to 6 years.

The data originate almost exclusively from UK laboratories and are managed by the British Oceanographic Data Centre. Data collection is ongoing at some sites (for example, Seven Stones Lighvessel) but these data are not managed by BODC. They are part of the Centre for Environment, Fisheries and Aquaculture Science (CEFAS) wavenet network.

  • The dataset includes measurements of currents, waves, temperature, salinity, sea level, attenuation and concentrations of suspended particulates. The data were collected off the Holderness coast (just north of the Humber Estuary, UK East Coast) during the winters of 1993-1994, 1994-1995 and 1995-1996. The experiment involved the deployment of mooring platforms, each holding a bottom pressure recorder, acoustic Doppler current profiler (ADCP), electromagnetic current meter (EMCM) and a transmissometer, at 8 stations along two lines off the Holderness coast. There were very little ADCP data for the 1993 and 1994 deployments. The River-Atmosphere-Coast Study (RACS) was the component of the LOIS programme looking at processes from the river catchment into the coastal sea. The Holderness Experiment data were collected by the Proudman Oceanographic Laboratory (POL) and the University of Hull. The data are held by the British Oceanographic Data Centre (BODC)

  • The dataset comprises measurements of hydrographic, bathymetric, sedimentary and meteorological parameters. These include water currents, temperature, salinity and wave parameters; suspended and seabed sediment; coastal geomorphological characteristics; and atmospheric temperature, pressure, humidity, irradiance and wind velocities. The study area was centred on the tidal inlet within the Peninsula do Ancao, Ria Formosa National Park, Algarve, Portugal. Field measurements were collected in the offshore area, the surf zone, beach experiments, the inlet areas and the inlet mouth between January and March 1999. The study utilised moorings, sediment grabs, tidal predictions, radar systems, acoustic Doppler current profiler (ACDP) surveys, a jack-up barge, beach experiments, video tower images, aerial surveys, seabed photographs and field campaign images. INDIA aimed to gain a better understanding of the interactions between tides, waves, currents and sedimentary processes at work in the European coastal zone with a view to predicting change. INDIA was coordinated by the University of Liverpool, Department of Civil Engineering. Data have been provided and/or modelled by a number of organisations from countries including France, Poland, Portugal, Australia, Netherlands, USA and the UK. 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 and fully documenting the data.

  • This dataset comprises metocean (current, wave,wind, meteorology and water level) data collected by oil companies Shell, BP and Total at their offshore oil and gas fields worldwide. It does not included the hindcast modelling simulations which were run on behalf of these oil companies; just the metocean measurements. Additionally, some data on the effect of water motion on platform stability, corrosion (dissolved oxygen concentration), ice thickness and movement and hydrography (vertical profiles of salinity, temperature and density and occasionally sound velocity) are included. The vast majority of the data were measured by instruments, although some human observations of wind speed and wave height and direction are also included. Geographic coverage is worldwide, according to the location of offshore oil and gas fields: NE and NW Atlantic, North Sea, Norwegian Sea, Mediterranean Sea, Adriatic Sea, Caspian Sea, Red Sea, Gulf of Aden, Gulf of Oman, Persian Gulf, Gulf of Mexico, Gulf of Guinea, South Atlantic, Magellan Straits, Sea of Okhotsk, Indian Ocean, South China Sea, Seram Sea, Malacca Straits, Makassar Strait. The earliest dataset was collected in 1961 and the most recent in 2010. Collection is ongoing. At present, there are over 2550 datsets covering more than 2000 years of observations of winds, waves, currents and sealevels.

  • The dataset contains a diverse range of environmental data ranging from estuary properties including geomorphology, water depth and habitat characterisation to detailed time series of parameters such as salinity and chemical and nutrient concentrations. The data are stored in a database containing a directory of existing data sources for estuaries; data for the broad properties of 79 UK estuaries; and detailed hydrodynamic, bathymetric, and sedimentary information for six estuaries: Blackwater, Humber, Mersey, Ribble, Southampton Water and Tamar. The data range from 1965 to 2002 and include both historic datasets and those collected during a recent effort (1997-2002) to enhance our knowledge of estuaries. Data collection employed a variety of instrumentation and techniques, including water, biota and sediment sample collection and analysis and the deployment of hydrographic instruments such as sea level, temperature, salinity and optical backscatter recorders. The Estuaries Research Programme (ERP) began in 1997 with the EMPHASYS project, which aimed to improve our understanding of processes operating in estuaries and use this knowledge to enhance broad scale modelling techniques that can be applied to estuarine processes. This work was funded by the Environment Agency/Department for Environment, Food and Rural Affairs (DEFRA) Flood and Coastal Defence Research and Development Programme. The data are managed by the British Oceanographic Data Centre (BODC) and are available on CD-ROM.

  • This dataset comprises 113 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in November 1994 from stations covering the East coast from The Wash to Berwick upon Tweed. 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) Rivers, Atmosphere and Coasts Study (RACS).

  • This dataset comprises 209 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in October 1994 along the NE coastal strip from Great Yarmouth to Berwick upon Tweed. 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 Land Ocean Interaction Study (LOIS) Rivers, Atmosphere and Coasts Study (RACS).

  • This dataset comprises 116 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in January 1995 from stations covering the North Sea coastal strip between Great Yarmouth and Berwick upon Tweed. 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 Plymouth Institute of Marine Studies as part of the Land Ocean Interaction Study (LOIS) Rivers, Atmosphere and Coasts Study (RACS).

  • This dataset comprises of suspended sediment, sediment transport and water column structure data collected at two sites in the mouth of the Dee Estuary, Liverpool Bay during February and March of every year from 2005 to 2009. Throughout each data collection cruise the RV Prince Madog underway monitoring system recorded latitude, longitude, ship speed and heading, depth, air temperature, air pressure, humidity, wind speed and direction, photosynthetically active radiation (PAR), sea temperature and salinity, beam transmission, fluorescence and, for 2009, dissolved oxygen concentration. At each site visit profiles of the water column were made over a 25 hour tidal cycle using a conductivity-temperature-depth (CTD) sensor package. Measurements include temperature, salinity, PAR, beam attenuation, particle scattering and transmission, fluorescence, and oxygen concentration. Additionally samples of salinity, suspended particulate matter and in-situ temperature at discrete depths within the water column were obtained and grab samples were taken from the sea-bed after each CTD cast. The RV Prince Madog also performed side-scan sonar tows. During the February cruises mooring frames were deployed on the sea-bed. These frames provided current profiles, particle size information, particle scattering information, bed ripple profiles, sediment settling velocity and temperature, salinity and pressure at each site. The mooring frames were recovered during the March cruises. The main aim of this research was to assess and advance the latest marine sediment transport models. These data allow this assessment to be made by providing information on the complex inter-dependence of sediment processes in the bottom boundary layer. The data were collected by the Proudman Oceanographic Laboratory (now the National Oceanography Centre). Data management was provided by the British Oceanographic Data Centre.

  • The data set comprises measurement of physical and biogeochemical oceanographic parameters and complementary meteorology collected during the Liverpool Bay/Irish Sea Coastal Observatory initiative. It includes measurements from across the Liverpool Bay and Irish Sea area with data collection spanning a decade from 2001 to 2011. It incorporates regular hydrographic survey cruises (typically 8 - 10 per year) undertaken by the RV Prince Madog, data collected via instrumented ferries, time series data from oceanographic moorings and at two meteorological stations, namely: Bidston Observatory (up to 2004) and Hilbre Island (2004 - 2011), and a shore-based high-frequency (HF) radar measuring waves and surface currents out to a range of 50km. The hydrographic surveys include conductivity-temperature-depth (CTD) casts with attached auxiliary sensors and data collected via the ships' underway monitoring system. Oceanographic parameters include temperature, salinity, dissolved oxygen, attenuance, turbidity, fluorescence, chlorophyll, nutrients, irradiance, waves and currents and meteorological parameters include air temperature, air pressure, wind velocities, humidity, precipitation and atmospheric irradiance. The instrumented ferries also incorporated an underway monitoring system for sea surface properties. The Observatory integrated (near) real-time measurements with the POLCOMS (Proudman Oceanographic Laboratory Coastal Ocean Modelling System) models. The objective was to understand a coastal sea's response both to natural forcing and to the consequences of human activity. The foci were the impact of storms, variations in river discharge (especially the Mersey), seasonality, and blooms in Liverpool Bay. The Observatory was coordinated at the National Oceanography Centre (previously the Proudman Oceanographic Laboratory, POL) in Liverpool and data are managed by British Oceanographic Data Centre (BODC). The data set is supplemented by infra-red (for sea surface temperature) and visible (for chlorophyll and suspended sediment) satellite data. These data are held at the NERC Earth Observation Data Centre /Remote Sensing Data Analysis Service (NEODC/RSDAS).
