Zooplankton and fish catch statistics comprising species identification and abundance. Fish maturity identification and abundance are also recorded for a sub-sample of the total catch. A proportion of the data relate to unidentified species and estimated abundances (or an indication of abundance magnitude) are often recorded. The data were obtained from the Rockall Trough region of the North East Atlantic Ocean between 1973 and 1979. This data set is based upon samples obtained by mid-water trawls from research vessels. It incorporates digital data recorded in field notebooks and reports, together with the results of a retrospective study, in 2010, of preserved specimens from the catches. The original data were collected by John Mauchline at the Scottish Marine Biological Association (SMBA) and re-examined in 2010 by scientists at the Scottish Association for Marine Science (SAMS).

The Catlin Arctic Survey created a unique collaboration between scientists and explorers to undertake field research in the Arctic. Each Catlin Survey comprised of two principle parts. The 'Catlin Ice Base', which was a stationary scientific research base located off the northern coast of Canada; and the 'Explorer Team', comprising of a small long-range specialist team moving on foot from close to the North Geographic Pole towards Greenland. The Catlin Ice Base consisted of temporary polar shelters and tents erected on the sea ice off the coast of Ellef Ringnes Island, Nunavut, Canada, 78°46'27" N / 104°42'49" W. In 2010 and 2011 during the second and third Catlin Arctic Surveys, scientists and explorers examined the upper layers of the Arctic Ocean's water column. In parallel, scientists from the US, UK and Canada conducted experiments at a unique research station on the frozen Arctic Ocean with the support of experienced polar explorers and guides. These datasets (as .xls and .csv files) resulted from the work carried out at the Ice Base. Here a group, of up to 10 scientists and operational staff, were able to collect and analyze samples from under the sea ice as well as deploy heavier instrumentation up to a depth of 200 metres. Scientists at the ice base made measurements of temperature, salinity, total alkalinity, DIC, nutrients, chlorophyll, zooplankton community structure and physiological responses to elevated pCO2 levels. The Catlin Arctic Survey has enabled the monitoring, measuring and collection of information to improve scientific understanding of the processes involved in, and the impacts of, climate change. The scientists researched how changes within the seawater beneath the floating sea ice may be affecting powerful ocean currents that influence prevailing climate and weather patterns worldwide. These data were collected as part of the Catlin Arctic Survey funded by Catlin Ltd. and coordinated by Geo Mission Ltd. Participants were supported by a Natural Environment Research Council (NERC) UK Fellowship, PML Lord Kingsland Fellowship, Ralph Brown Expedition Grant from the Royal Geographical Society, NERC's National Centre for Earth Observation, World Wildlife Fund for Nature and Fisheries and Oceans Canada.

The dataset comprises physical, biogeochemical and biological measurements from the Southern Ocean. The data were collected in the Bransfield and Gerlache Straits and Bellingshausen Sea between 1995 and 1996. Hydrographic casts provided profiles of temperature, salinity, dissolved oxygen, transmittance, chlorophyll and photosynthetically active radiation, while water samples were analysed for bacteria, zooplankton and a biogeochemical parameters such as nutrient concentrations. Sediment cores were also analysed for nutrients, while drifting traps provided sedimentation flux measurements and shipboard experiments yielded production data. The majority of measurements were collected during two consecutive cruises of the BIO Hesperides between early December 1995 and early February 1996. The hydrographic profiles were collected using a CTD and the data were stored as approximately 300 individual ASCII files per cruise, with data stored at 1dbar resolution. Several hundred discrete measurements (water samples and sediment cores) were collected in total. An array of moorings deployed for one year in the Western Bransfield Strait Basin provided sediment trap samples for biological and biogeochemical analysis. The FRUELA project was part of the Spanish contribution to the study of biogeochemical carbon fluxes in the Southern Ocean. Three major zones, with contrasting physico-chemical and biological characteristics were considered: Bellingshausen, including the Northwest Bellingshausen Sea and comprising the southern boundary of the Antarctic Circumpolar Current (SbyACC); Bransfield, including the Western Bransfield Strait and the northeastern part of the Gerlache Strait; and Gerlache, including the rest of the Gerlache Strait. The research involved a number of Spanish institutions and was coordinated by the University of Oviedo and the Institute of Marine Sciences (CSIC). The data are held by the British Oceanographic Data Centre.

The data set comprises hydrographic and biogeochemical and biological measurements including temperature, salinity, currents, chlorophyll, dissolved organic and inorganic carbon and nitrogen, suspended matter concentrations, nutrients, plankton and fish. The results of primary production experiments are also included. The data were collected from the Bristol Channel, Severn Estuary, Celtic Sea and Plymouth Sound between 1971 and 1983. Measurements were taken over a series of more than 100 cruises, many with more than 50 stations. The most intensive sampling took place before 1975. The original data were collated and stored at Institute for Marine Environmental Research (IMER), which became Plymouth Marine Laboratory in 1988. As this is a large and important data set, which was previously held in an inaccessible format, it was selected for long-term archival at BODC as part of the NERC SEEDCORN programme. The data have been extracted, loaded into a relational database and are available on CD-ROM.

This dataset includes physical, biological and biogeochemical measurements of both the water column and seabed sediments. Hydrographic data include temperature, salinity, attenuance, dissolved oxygen, fluorescence, photosynthetically active radiation (PAR), sound velocity and current velocities, while biogeochemical analyses of water samples provided measurements of nutrients and biological sampling provided measurements of zooplankton abundance. A large number of benthic parameters were measured, including concentrations of substances such as nutrients, metals and carbon in both sediments and sediment pore waters. Benthic fauna were also studied, while rates of sedimentation flux were quantified. These oceanographic and benthic data were supplemented by satellite ocean colour imagery. The data were collected in the North Atlantic Ocean at the Mouth of Rockall Trough, Hatton-Rockall Basin and the Flank of Feni Drift between August 1997 and June 1999 over four cruises, comprising a preliminary site assessment (CD 107 August, 1997) followed by two process cruises (CD 111, April-May 1998, and CD 113, June-July 1998). A further cruise (CH 143) was part-funded by BENBO to retrieve moorings. The data were collected using a variety of instrumentation, including shipboard deployment of conductivity-temperature-depth (CTD) profilers with attached auxiliary sensors, benthic samplers, landers, cameras and incubation chambers, water samplers and continuous underway sensors. These were supplemented by moored sensor and satellite data. The BENBO programme was led by the Scottish Association for Marine Science/Dunstaffnage Marine Laboratory involved researchers from Southampton Oceanography Centre, Scottish Universities Research and Reactor Centre, Plymouth Marine Laboratory, Lancaster University, Leeds University, Edinburgh University, Cambridge University and the University of Wales, Bangor.

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 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.

The programme involved two major fieldwork activities: a deep ocean research cruise and a programme of freshwater studies. The marine component of the dataset generated a total of 430 distinct variables, quantifying the meteorology, hydrography, chemistry, biogeochemistry, and the microbial plankton (bacteria, phytoplankton and microzooplankton) biomass, taxonomic composition along the 5500 km cruise track in the Indian Ocean during August-September 2001. Measurements were mainly made on water samples collected either from the sea surface while the ship was underway or from a range of depths during conductivity-temperatue-depth (CTD) and water sampling stations at each of 11 sites occupied in the Indian Ocean. The maximum depth sampled at open ocean sites ranged from 300 to 3000 m. Short sections of 300 m deep CTD and fluorescence profiles were also obtained using a moving vessel profiler (MVP). The freshwater component of the dataset generated variables from Priest Pot in the Lake District and from a range of other freshwater sites around the UK. It contains underpinning weekly time-series measurements characterising the physical, chemical and biological condition of the water column at the Priest Pot sampling site between 2002-2004, together with data from studies focused on the seasonal and spatial dynamics of viruses, bacteria and picophytoplankton, trace metal distribution and the ubiquity of microbial protists. The database also contains 376 gene sequences from genetic material extracted from environmental samples. The programme was a 5-year Thematic Programme funded by the Natural Environment Research Council (NERC) and the purpose of the study was to improve understanding of aquatic microbial biodiversity, with the emphasis on community interactions, ecosystem function (e.g. biogeochemical cycling of carbon and nutrients, and the potential for biotechnological exploitation. The programme involved scientists from the Plymouth Marine Laboratory, the National Oceanography Centre Southampton, University of Cardiff School of Biosciences, University of Cardiff School of Earth and Ocean Sciences, University of Warwick School of Biological Sciences, University of Newcastle School of Civil Engineering and Geosciences, University of Bristol School of Biological Sciences, University of Oxford Department of Zoology, University of Liverpool School of Biological Sciences, University of Stirling School of Biological and Environmental Sciences, the Marine Biological Association of the UK, Lancaster University Department of Environmental Science and the Centre for Ecology and Hydrology (CEH) Lancaster and Dorset.
