  • This dataset comprises 123 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during June - July 1995 from stations in the Humber-Wash and Humber-Tweed Land Ocean Interaction Study (LOIS) grids. 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 Southampton Department of Oceanography as part of the Land Ocean Interaction Study (LOIS) Rivers, Atmosphere and Coasts Study (RACS) .

  • This dataset comprises 47 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in October 1989 from stations covering the southern North Sea (south of 56N). 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 North Sea Project Air-sea Exchanges Process Study.

  • The Antarctic Deep Water Rates of Export (ANDREX) dataset comprises hydrographic and biogeochemical data. Measurments include temperature; salinity; currents; concentrations of geochemical tracers such as chlorofluorocarbons (CFCs), sulphur hexafluoride (SF6), freon, tritium, radiocarbon and noble gases; alkalinity; dissolved oxygen and partial pressure of carbon dioxide (pCO2); and nutrient concentrations (nitrate, silicate and phosphate). These data are supplemented by meteorological (air pressure, air temperature, wind velocity, relative humidity, radiation) and bathymetric measurements. The data were collected along a track running from the tip of the Antarctic Peninsula to 30 deg E that corresponds to the northern limb of the Weddell gyre within the Atlantic sector of the Southern Ocean. Data collection was undertaken in December 2008-January 2009 and March-April 2010 over two UK research cruises. In 2008 the section was aborted approximately halfway due to a medical evacuation. The track was completed during the second cruise in March-April 2010. Data were collected via the deployment of conductivity-temperature-depth (CTD) profilers, accompanied by lowered acoustic Doppler current profilers (LADCPs), at numerous stations along the cruise track. This permitted the collection of water samples for biogeochemical analyses. In addition to measurements at individual stations, various parameters were measured continuously throughout each cruise, including current velocities (using a vessel mounted ADCP, VMADCP), water depth and surface ocean and meteorological properties. These data will be supplemented by measurements collected on a US CLIVAR section (a WOCE I6S repeat) between South Africa and Antarctica along 30deg E in January-February 2008. The ANDREX project aims to enhance our understanding of the role of the Weddell gyre in the meridional overturning circulation, in ventilating the deep ocean and in sequestering carbon and nutrients in the global deep ocean. ANDREX is a joint effort between UK, German and US research institutes, including the National Oceanography Centre (UK), the University of East Anglia (UK), British Antarctic Survey (UK), the University of Manchester (UK), Woods Hole Oceanographic Institution (USA) and the Alfred Wegener Institute (Germany). The UK principal investigator (PI) is A. Naveira Garabato from the School of Ocean and Earth Science, NOC. Data collected during the UK cruises will be managed by the British Oceanographic Data Centre (BODC) but those collected on the US CLIVAR section will not be held at BODC.

  • The Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean (DIMES) UK data set comprises hydrographic data, including measurements of temperature, salinity, currents and turbulence, supplemented by bathymetric and meteorological data. The study area is located within the Antarctic Circumpolar Current (ACC) in the southeast Pacific, Drake Passage and Scotia Sea regions of the Southern Ocean. Data collection began in December 2009 and ended in April 2014. The data were collected via a combination of research cruises in the southern hemisphere summer seasons. Three cruises were intended (UKD-1, UKD-2 and UKD-3) a further three cruises were completed (UKD-2.5, UKD-4 and UKD-5). Shipboard data collection involved the deployment of conductivity-temperature-depth (CTD) packages, accompanied by lowered acoustic Doppler current profilers (LADCPs), and Vertical Microstructure Profilers (VMPs) in a grid pattern across the study area. Continuous measurements of current velocities (using vessel mounted ADCPs, VMADCPs), bathymetry and surface ocean and meteorological properties were collected throughout each cruise. An inert chemical tracer (sulphur hexafluoride, SF6) was released into the ACC in early 2009, and subsequent cruises measured temporal changes in the tracer distribution via the analysis of water samples collected at CTD stations. In addition, a mooring cluster was deployed in Drake Passage in early 2009 provided approximately two years' worth of hydrographic time series data. Floats and drifters were also deployed in the 2009 and 2010 seasons. The DIMES project aims to enhance understanding of mixing processes in the Southern Ocean, as it is thought that such processes may significantly affect ocean energetics and property balances, and thus have implications for the accuracy of climate models. DIMES brings together researchers from both UK and US institutions, including the National Oceanography Centre (NOC), the University of East Anglia (UEA), British Antarctic Survey (BAS), the Scottish Association for Marine Science (SAMS), Woods Hole Oceanographic Institution (WHOI), Scripps Institute of Oceanography, Florida State University, the University of Washington and Massachusetts Institute of Technology (MIT). The UK principal investigator (PI) is A. Naveira Garabato from NOC and the UK data will be managed by the British Oceanographic Data Centre (BODC). Data collected on US cruises, including all float and drifter data, will be managed by US institutions and are not held at BODC.

  • The Southern Ocean Fine structure (SOFine) dataset comprises hydrographic (temperature, salinity, current velocities, microstructure and turbulence), bathymetric and meteorological (air temperature, pressure, winds, humidity and irradiance) measurements from the Kerguelen Plateau region of the Southern Ocean. The data were collected between late 2008 and early 2010 via one research cruise (November - December 2008) and two long-term mooring deployments (November 2008 - January 2010). Data collection involved the deployment of a conductivity-temperature-depth (CTD) package accompanied by lowered acoustic Doppler current profilers (LADCPs) at numerous locations across the study area. Microstructure was measured using a freefall Vertical Microstructure Profiler (VMP) and opportunistic measurements of upper ocean turbulence were collected with a tethered ISW Wassermesstechnik microstructure profiler. The station data were supplemented by continuous underway measurements of current velocities (using a vessel mounted ADCP, VMADCP); bathymetry (using single- and multi-beam echosounders); and surface ocean and meteorological parameters. Floats and drifters were also deployed, as were five moorings: three were recovered approximately 2.5 weeks later during the cruise and two were deployed for more than one year. The moored instruments measured physical parameters such as temperature, conductivity and pressure, horizontal and vertical current velocities (using moored ADCPs) and turbulence (using moored microstructure profilers, MMPs). The SOFine project aimed to enhance our understanding of frictional processes that slow the Antarctic Circumpolar Current (ACC) and help to drive the Southern Ocean overturning circulation. SOFine involved researchers from UK, US, Australian and German institutions, including the National Oceanography Centre (NOC), the University of East Anglia (UEA), British Antarctic Survey (BAS), Woods Hole Oceanographic Institution (WHOI), the Commonwealth Scientific and Industrial Research Organisation (CSIRO), the University of Tasmania and the Leibniz Institute of Marine Sciences (IFM-GEOMAR), University of Kiel. The UK principal investigator (PI) is A. Naveira Garabato from the School of Ocean and Earth Science, NOC and the majority of the data are managed by the British Oceanographic Data Centre (BODC). The float and drifter data are managed by the Argo programme and Australian research institutions, and are not held at BODC.
