The data set contains a variety of physical, chemical and biological parameters. Hydrographic profiles provided temperature, salinity, fluorescence, dissolved oxygen and transmissance measurements, which were supplemented by time series of surface ocean and meteorological properties. Time series of current velocities, temperature and sea level were also collected. Biogeochemical and biological analyses of water samples provided nutrient, phytoplankton and zooplankton data, while production data were derived from incubation experiments. The data were collected at seven stations in the Celtic Sea with varying physical and biological characteristics. Fieldwork was undertaken between 15th and 29th May 2000, with each station being occupied for 24 hours. Data were collected via shipboard deployment of CTD profilers and undulators with accompanying auxiliary sensors, and discrete water sampling. Further data were obtained from three moorings including acoustic Doppler current profilers (ADCPs), temperature recorders and bottom pressure recorders that were also deployed and recovered during the study period. Measurements were collected during RRS Discovery cruise D246 as part of the multidisciplinary study of the interactions between physical processes and biological production in contrasting pelagic shelf waters. An additional goal of the study was to map the tidal front situated in the St George's Channel. The study was co-ordinated by Plymouth Marine Laboratory and the research involved 28 scientists and technicians from 14 separate institutions situated in five different countries. Data are managed by the British Oceanographic Data Centre.
The dataset comprises a wide range of physical and biogeochemical oceanographic and atmospheric parameters, plus additional biological measurements and observations. Hydrographic parameters include temperature, salinity, current velocities, fluorescence and attenuance, while biogeochemical and biological analyses of water samples provided measurements of dissolved gases, hydrocarbons, sulphur species, dissolved organic carbon (DOC), halocarbons, nutrients, pigments, bacteria, phytoplankton and zooplankton. Bird identification and cetacean abundance studies were also undertaken, as were tracer release experiments using both inert chemical (sulphur hexafluoride, SF6) and bacterial (Bacillus globigii) tracers. Meteorological data were also collected, including concentrations of various chemicals, supplemented by standard measurements of air temperature, pressure, irradiance, humidity and wind velocities. The data were collected in the North Atlantic Ocean and North Sea between 1996 and 1998, as follows: Eastern Atlantic off the coast of Ireland (June-July 1996 and May 1997); southern North Sea (October-November 1996); and North Eastern Atlantic between the UK and Iceland (June-July 1998). The data were collected during four cruises (RRS Challenger CH127, CH129, CH133 and RRS Discovery D234) using a variety of equipment, including instrumentation deployed at sampling stations (e.g. conductivity-temperature-depth (CTD) profilers) and underway sensors that ran throughout each cruise, yielding continuous measurements of both hydrographic and meteorological parameters. Discrete air and water samplers were also used to measure atmospheric and hydrographic parameters throughout each cruise. The data collection periods were associated with individual ACOSE air-sea exchange experiments: two Eastern Atlantic Experiments (EAE96 and EAE97); ASGAMAGE in the southern North Sea; and the North Atlantic Experiment, NAE. ACSOE was a 5-year UK NERC Thematic Research Programme investigating the chemistry of the lower atmosphere (0 - 12 km) over the oceans. The Marine Aerosol and Gas Exchange (MAGE) study group was the only component of the ACSOE Project that included measurements in the marine environment. ACSOE data management was a shared responsibility between the British Atmospheric Data Centre (BADC) and the British Oceanographic Data Centre (BODC). BODC handled the management of ship data as well as all other data collected in the water column during the ACSOE/MAGE cruises. BODC assisted in the onboard collection and subsequent working up of ship data, and assembled all marine data in BODC's relational database carrying out quality control and data processing as required. ACSOE was led by Prof. Stuart Penkett of the University of East Anglia and cruise principle scientists included representatives of the University of Newcastle Upon Tyne, and the University of East Anglia.
The Northern Seas Programme dataset comprises hydrographic, biogeochemical, biological and meteorological data. Hydrographic profiles provided measurements of parameters such as temperature, salinity, fluorescence and dissolved oxygen, while current velocities and acoustic backscatter were also measured. A comprehensive water sampling program permitted the collection of biogeochemical data including concentrations of various organic compounds, dissolved gas concentrations and radioactivity. Water samples were also analysed for phytoplankton, zooplankton and viruses. Larger biological samples were obtained from the water column using trawl nets and cetacean distributions were monitored using hydrophone arrays. Sediment samples were collected at various locations and analysed for biogeochemical parameters and zoobenthos. Sample data were supplemented by those derived from experiments, while bathymetry and meteorological parameters were measured across the study area. Data collection was undertaken in the Irish and northern North Seas, across the NE Atlantic and up to the marginal Arctic pack ice zone. This includes the territorial waters of the UK, Norway and the Russian Arctic, and extends from coastal fjords to the ocean margins. The data were collected during the period 2001-2007 over a number of cruises: RRS Discovery cruise D257, RRS James Clark Ross cruises JR75 and JR127, RRS Charles Darwin cruise CD176 and FS Poseidon cruise PO300/2. Measurements were taken using a variety of instrumentation, including conductivity-temperature-depth (CTD) profilers with attached auxiliary sensors, bathymetric echosounders, sediment samplers, trawl nets and acoustic Doppler current profilers (ADCPs), while incubation chambers were used for shipboard experiments. The programme was designed to advance the understanding of how marine systems in Northern Seas respond to environmental and anthropogenic change and was developed in three themes: Theme A - Understanding fjordic systems insights for coastal and oceanic processes; Theme B - Ocean Margins: the interface between the coastal zone and oceanic realm; Theme C - Measuring and modelling change: sea sensors and bioinformatics. Theme B included the Ellett Line Time Series. The Northern Seas Programme was co-ordinated by the Scottish Association for Marine Science (SAMS). Data from the programme are held at the British Oceanographic Data Centre.
The dataset comprises a diverse set of physical, chemical and biological data including: bacteria, carbon, chlorophyll, dissolved gases, light levels, nutrients, phytoplankton, productivity, respiration, salinity, temperature, trace elements and zooplankton. Measurements were gathered from the North Atlantic and Norwegian fjord waters between 1971 and 1998. The data arise from three sources: biological and hydrographic data collected between 1971 and 1975 at Ocean Weather Ship (OWS) India in the North Atlantic; conductivity-temperature-depth (CTD) casts, water samples, net samples and meteorological data from the four week Bergen Mesocosm experiment at Espegrend Marine Biological Field Station (Norway) in 1995; and the six week RRS Discovery cruise 221 to the North East Atlantic in 1996, where physical, chemical and biological data were collected. The data were collected using a variety of methods including: more than 500 CTD and SeaSoar profiles; nearly 1000 water bottle samples; over 600 net hauls; over 450 Secchi disk deployments; nearly 4000 multisizer samples; 23 production experiments; four drifting buoy tracks and 40 days of weather observations. The PRIME programme aimed to lay the basis for mathematical models to describe the role of plankton in biogeochemical fluxes within the oceans which have implications for climate regulation. The project was hosted by the School of Ocean Sciences, University of Wales, Bangor. Data management was undertaken by the British Oceanographic Data Centre and over 95% of the data collected are now assembled on a CD-ROM. The data are accompanied by an extensive users' guide (covering sampling protocol documentation), the structures used to store the data, and the data interrogation tools.
This cross-disciplinary project resulted in a diverse data catalogue. This includes meteorology (2-D wind speed and direction, total irradiance, Photosynthetically Active Radiation/PAR, air temperature, atmospheric pressure, humidity); atmospheric composition (chemical analyses of aerosol particle composition) and biological, chemical and physical properties and processes in the photic zone (optical properties of the water column; chlorophyll concentration; photosynthetic pigment composition; primary production; bacterial production; phytoplankton and bacterial speciation; concentrations of biogenic trace compounds such as iodocarbons, methyl bromide, dimethyl sulphide/DMS and dimethyl sulphoniopropionate/DMSP; trace gas production; plankton community composition; nutrient concentration; concentrations of trace metals such as iron; salinity; temperature; Dissolved Organic Matter - particulate carbon, nitrogen and phosphorus; phytoplankton growth rates, grazing mortality and viral lysis; ammonium regeneration, nitrification and nitrogen fixation; gross production, net community production and dark community respiration; zooplankton ecology). The fieldwork included two dedicated research cruises in the eastern North Atlantic Ocean, spanning the period April - May 2004. Measurements of nutrient cycling and biological activity were monitored prior to and after deployment (IN stations) of patches fertilised with iron and phosphate relative to several (OUT stations) controls. Measurements were taken using a variety of instrumentation, including conductivity-temperature-depth (CTD) profilers with attached auxiliary sensors and acoustic Doppler current profilers (ADCPs), while incubation chambers were used for shipboard experiments. Samples were collected with Niskin bottles attached to the CTD frame at different depths in the water column and samples analysed onboard or preserved for analysis back in the laboratory. The FeeP data set was intended to advance understanding of how the supply and mutual interactions between iron and phosphate control biological activity and fluxes in the subtropical North Atlantic. The study led by the Plymouth Marine Laboratory (PML) united marine scientists from institutions across the UK and international collaborators. It was funded by the UK Natural Environment Research Council. The data are held at the British Oceanographic Data Centre (BODC) and have been incorporated into the National Oceanographic Database (NODB).
The data set comprises hydrographic, biogeochemical and biological data, including measurements of temperature, salinity and attenuance, plus concentrations of parameters such as nutrients, pigments, urea, hydrocarbons, sedimentation flux, sulphur and dissolved carbon. Analyses of bacterial, zooplankton and phytoplankton communities were also undertaken. The oceanographic data were supplemented by measurements of surface meteorological parameters. Data were collected across three repeated sections: one along the Gulf of Oman; a section at 67deg East from 8 to 14.5deg North; and a major section from 8deg North, 67 deg East to the coast of Oman. Other one-off sections were also traversed in the Arabian Sea and Gulf of Oman areas. Measurements were collected during two cruises: one between 27 August and the 4 October 1994 and the other between the 16 November and the 19 December 1994. Sections were covered by underway surface ocean measurements (one minute sampling of multiple parameters providing some 5 million measurements) complemented by a total of 21 CTD/water-bottle stations, 14 of which were repeated. ARABESQUE was organised by the Plymouth Marine Laboratory of NERC's Centre for Coastal and Marine Sciences and involved the University of Wales, Bangor; Queen's University of Belfast; University of East Anglia; University of Edinburgh; University of Newcastle; the Bedford Institute of Oceanography, Canada; the Max Planck Institute for Limnology, Germany and the Sultan Qaboos University, Oman. 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, calibrating, quality controlling and fully documenting the data. BODC checked for instrument spikes or malfunction, values beyond the calibration range, unreasonable ratios of chemical constituents and unreasonable deviations from climatological means. Data were assembled into a relational database, complete with supporting documentation and a user manual. The full data set has been published by BODC on CD-ROM complete with user interface.
The data set comprises a diverse collection of physical, chemical and biological measurements, encompassing well over 1000 parameters. There are data from over 1000 conductivity-temperature-depth (CTD)/rosette stations, over 440 core profiles, over 180 sediment trap samples, over 140 net hauls and much, much more. The primary study area was a box extending to the base of the slope from Vigo to Cap Finistere. However, data are included from both further offshore (filament tracking) and from the Portuguese Margin. Measurements were taken from November 1996 to October 1999 during 33 cruise legs, involving research vessels from seven nations. Data were collected using a variety of equipment and techniques, including expendable bathythermographs (XBTs), turbulence probes, CTDs and oceanographic undulators with auxiliary sensors. These hydrographic profiles were accompanied by net hauls, plankton recorder deployments, sediment cores and a comprehensive water sampling programmes during which a wide variety of chemical and biological parameters were measured. The station data were supplemented by underway measurements of oceanographic and meteorological properties. Results from production and phosphate uptake experiments are also included in the dataset, as are bathymetric data from multibeam (swath) surveys, coastal upwelling measurements and data from moored instruments and benthic landers. The dataset also includes imagery from satellites, seabed photography and X-ray photographs of core samples. The aim of the project was study biogeochemical processes at the shelf break and to quantify the fluxes of material between the shelf and the open ocean. The project brought together over 100 scientists from 40 research centres and universities throughout Europe. The British Oceanographic Data Centre (BODC) is assembling the data sets collected during OMEX II into its project database system and the data set is also available on CD-ROM.
The dataset comprises hydrographic profiles (temperature, salinity, oxygen, fluorometer, transmissometer, irradiance) and along track measurements (bathymetry, surface meteorology, sea surface hydrography), with discrete measurements including water chemistry (organic and inorganic nutrients, particulate organic carbon and nitrogen, dissolved gases, trace metals), biology (phytoplankton, zooplankton, primary production, community respiration, chlorophyll, pigments) and atmospheric particulates (major ions, organics and trace metals). Data have been collected from meridional transects of the Atlantic Ocean (between the UK and the Falkland Islands, South Africa or South America) from 1995 to the present day. The Atlantic Meridional Transect (AMT) programme aims to study the factors determining the ecological and biogeochemical variability of planktonic ecosystems in the tropical and temperate Atlantic Ocean, and their links to atmospheric processes. The majority of the data are available to academia for re-use and re-purpose but data from recent cruises may be subject to a moratorium which allows first use for data originators. The AMT is coordinated by Andy Rees (AMT Principal Investigator) and Miss Dawn Ashby (AMT Project Officer) at the Plymouth Marine Laboratory (PML) in conjunction with the National Oceanography Centre. Since its inception the programme has involved researchers from several different countries and has acted as a platform for national and international collaboration. Data are managed by the British Oceanographic Data Centre.
The data set comprises a diverse collection of physical, chemical and biological measurements, encompassing over 1000 parameters. There are data from over 1650 conductivity-temperature-depth (CTD)/rosette stations, over 300 core profiles, over 370 sediment trap samples and much, much more. Most of this effort was directed at the region of the east Atlantic margin between La Chapelle Bank and the Goban Spur (between France and Ireland). In addition, there were two secondary areas of interest: the Norwegian Shelf Break just off Tromso and the Iberian Margin, either off Vigo or in the vicinity of the Tagus estuary. Measurements were collected from April 1993 until the end of December 1995 during 55 research cruise legs. Data were collected using a variety of equipment and techniques, including expendable bathythermography (XBTs), CTDs and oceanographic undulators with auxiliary sensors. These hydrographic profiles were accompanied by net hauls, plankton recorder deployments, sediment cores and comprehensive water and air sampling programmes during which a wide variety of chemical and biological parameters were measured. The station data were supplemented by underway measurements of oceanographic and meteorological properties. Results from production and trace metal experiments are also included in the dataset, as are bathymetric data from the British Oceanographic Data Centre (BODC) GEBCO digital Atlas, air-sea flux measurements and data from moored instruments and benthic landers that were deployed for periods from a few weeks to a year. The dataset also includes imagery from satellites, water column and seabed photography, scanning electron micrographs and X-ray photographs. FORTRAN source code for biogeochemical models developed during OMEX I is also included. The aim of the project was to study biogeochemical processes at the shelf break and to quantify the fluxes of material between the shelf and the open ocean. OMEX I involved scientists from 30 institutions in 10 countries. BODC is assembling the data sets collected during OMEX I into its database system and the data are also available on CD-ROM.
