  • The Joint Air-Sea Interaction (JASIN) 78 Project Data Set comprises a variety of measurements including upper air and near surface meteorology, and physical oceanography. Meteorological data include air temperature, pressure, humidity and wind, while oceanographic data include temperature, salinity, currents, wave spectra and short-term wave statistics. The data were collected in the North Rockall Trough, an area of deep water (1000m - 2000m) several hundred kilometres off the west coast of Scotland. The experiment lasted for 2 months from mid-July to mid-September 1978 and comprised 2 intensive observational phases preceded by a preparatory test period. Data were collected using a variety of instrumentation, with meteorological data being provided by radiosondes, tethered balloons, and ship- and aircraft-mounted sensors. Hydrographic data were collected via shipboard deployment of conductivity-temperature-depth (CTD) sensor packages (both standard and yoyo profiles), towed thermistor chains, ship-mounted wave recorders and moored temperature and current meters. The JASIN Project was designed to study the interaction of the atmospheric and oceanic boundary layers with the large scale motions of the sea and air. The multiplicity of processes sampled necessitated a large experiment and involved more than 50 teams of investigators from nine countries. The data are held at the British Oceanographic Data Centre and many series are available via BODC's online data delivery portal.

  • This dataset comprises 61 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in June 1995 from stations in the Humber-Wash grid and Humber-Tweed grid. 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 Plymouth Marine Laboratory as part of the Land Ocean Interaction Study (LOIS) Rivers, Atmosphere and Coasts Study (RACS).

  • This dataset comprises 17 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during November - December 1993 from the Eastern North Sea coastal zone from the Tweed Estuary to the Humber. 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 Plymouth Marine Laboratory as part of the Land Ocean Interaction Study (LOIS) Rivers, Atmosphere and Coasts Study (RACS).

  • This dataset comprises 31 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in December 1993 from stations covering the East coast from The Wash to the Tyne. 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 20 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in October 1994 from stations covering the North Sea coastal zone 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 Plymouth Marine Laboratory as part of the Land Ocean Interaction Study (LOIS) Rivers, Atmosphere and Coasts Study (RACS).

  • This dataset consists of a variety of hydrographic, biological, biogeochemical and meteorological data. Underway automatic sampling followed by flow cytometry was used for assessing mesoscale spatial variability of microorganisms. Coarse-scale (CTD) and fine-scale (PumpCast profiler) vertical distribution of microorganisms was determined, with dominant microbial prokaryotic and eukaryotic groups quantified by flow cytometry. Samples were collected and processed for subsequent molecular identification of flow cytometrically sorted dominant microbes. Abundance of larger microplankton organisms was assessed. Microbial respiration in the twilight zone was studied. Group-specific uptake of bicarbonate, phosphate and different nitrogen compounds was determined and group-specific production and grazing assessed using flow sorting. The ambient turnover rates of phosphate, organic phosphorus and labile dissolved organic matter, e.g. amino acids, was bioassayed. In order to put the microbial community data into context, physical and chemical parameters were measured. A ship mounted Acoustic Doppler Current Profiler (ADCP) was used to collect information about physical, mesoscale spatial context and, when combined with turbulence profiler data, SeaSoar profiler data and data collected using intensive Conductivity, Temperature and Depth (CTD) sampling for dissolved inorganic nutrients, may estimate mesoscale nutrient fluxes into the photic zone. PELAGRA neutral buoyancy sediment traps were used to estimate biogenic sedimentation. Samples were collected for particulate calcite, opal, and Particulate Organic Matter (POM) measurements, together with the isotopic composition of Particulate Organic Nitrogen (PON). Data collection was in the North Atlantic subtropical gyre between 9th August and 15th September 2011 during RRS Discovery cruise D369. The data were collected as part of the United Kingdom (UK) Natural Environment Research Council (NERC) Oceans 2025 programme (Theme 2). D369 was the last of three National Oceanography Centre 'process study' research cruises to be run by the Ocean Biogeochemistry and Ecosystems research group under the NERC Ocean 2025 research programme. The Principal Scientist was Mikhail V Zubkov of National Oceanography Centre, Southampton. Data from this cruise are held at the British Oceanographic Data Centre.

  • This dataset comprises 38 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during September – October 1999 along the Atlantic Meridional Transect (AMT) from the UK to Montevideo, Uruguay. 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 Plymouth Marine Laboratory as part of the Atlantic Meridional Transect (Phase 1) programme.

  • This dataset comprises 33 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during September - October 1998 along the Atlantic Meridional Transect (AMT) from the UK to the Falkland Islands. 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 Plymouth Marine Laboratory as part of the Atlantic Meridional Transect (Phase 1) programme.

  • 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.
