  • Data from this project is a UK contribution to a US research cruise that aimed to examine the impact of wave breaking and bubble processes on air-sea gas exchange. Measurements were made of whitecap fraction, wave state, wave bubble statistics and bubble properties beneath breaking waves on the R/V Knorr KN213-3 cruise departing Nuuk, Greenland October 9, 2013 arriving at Woods Hole, USA on November 12, 2013. Instruments and platforms used included an 11 meter long free-floating spar buoy equipped with wave wires, a bubble camera, acoustic resonators, a Waverider buoy and ship measurements of aerosol fluxes. Data generation were funded by NERC parent grant NE/J020893/1 awarded to Professor Ian Brooks and associated child grants NE/J020540/1 and NE/J022373/2 awarded to Mr Robin Pascal and Dr Helen Czerski respectively.

  • The data set comprises temperature and salinity hydrocasts collected across the North Atlantic Ocean between 1910 and 1990. The measurements were collected by nine North Atlantic Ocean Weather Ships (OWS): OWS Alpha (1954 – 1974); OWS Bravo (1928 – 1974); OWS Charlie (1910 – 1982); OWS Echo (1910 – 1979); OWS India (1957 – 1975); OWS Juliet (1950 – 1975); OWS Kilo (1949 – 1973); OWS Lima (1948 – 1990); OWS Mike (1948 – 1982). This data set also includes measurements collected close to the general positions prior to the stationing of the Weather ships for the OWS Bravo, Charlie and Echo stations. Data from OWS Alpha, Bravo, Echo, India, Juliett and Kilo have been taken from the US National Oceanographic Data Center (NODC) compilations whereas those from OWS Charlie, Lima and Mike have been constructed from both the US NODC and International Council for the Exploration of the Seas (ICES) data holdings. In addition a daily averaged data set for OWS Charlie is available for the period 1975 - 1985 (supplied by Syd Levitus). This data set was supplied to the British Oceanographic Data Centre (BODC) by ICES. Additional files and more recent data can be acquired from the ICES website.

  • This dataset comprises sea surface temperature measurements taken close to the time of high water at intervals of three to four days. The measuring programme consisted of approximately 50 observing sites around the shoreline of England and Wales and the data set spans the time period from 1963 to 1990. A few observing sites were already in existence when the network was established, for example observations at the Seven Stones and Varne Light Vessels go back as far as 1905. The Ministry of Agriculture, Fisheries and Food Lowestoft Fisheries Laboratory (MAFF), now known as the Centre for Environment, Fisheries and Aquaculture Science Lowestoft Laboratory (CEFAS) - part of the Department for Environment, Food and Rural Affairs (Defra), set up a database for these data, supplemented by both the earlier data and also by data from non-MAFF sources. Data from 1963 until 1990 are held at the British Oceanographic Data Centre (BODC). The time series is ongoing but data later than 1990 are not stored at BODC, these data are available from CEFAS.

  • This dataset comprises measurements of microbial uptake activities of betaine and choline, particulate phase osmolytes, amplicon sequencing of marker genese involved in Nitrogenous-osmolyte catabolism, and single cell genome data. Water samples were collected from at the L4 station of the Western Channel Observatory between April 27, 2015 to April 24, 2017 using Niskin bottles attached to a rosette sampler deployed from the RV Plymouth Quest. Nitrogenous osmolytes (glycine betaine, choline and trimethylamine N-oxide are essential components for most organisms in the marine environment. They enable cells to exist in a salty environment, but also have several other proposed uses. The aim of the project is to understand the seasonal cycle of glycine betaine, trimethylamine N-oxide and choline at Station L4. The water samples were analysed for the microbial assimilation and dissimilation activities using 14C labelled betaine and choline, respectively. The data will be incorporated to the European Regional Seas Ecosystem Model (ERSEM) coupled with the hydrodynamic model General Ocean Turbulent Model (GOTM) to simulate the N-osmolyte cycling at the L4 station. The data were collected under the project Biogeochemical cycling of N-osmolytes in the surface ocean funded by NERC Discovery Science grants NE/M002233/1 (parent), NE/M003361/1 (child), NE/M002934/1 (child). The grants were led by Dr Yin Chen, Dr Ruth Airs, and Dr Wei Huang respectively.

  • The data set comprises of measurements of surface currents collected across the Indian Ocean in the region 50 E (the Gulf of Aden) to 100 E and 25 S to 10 N. The data were collected between 1854 and 1974. The surface currents, measured from ships' drift, have been compiled into 10 day periods and 1 degree latitude-longitude squares. For each of these the vector mean of all of the observations from all years has been calculated. With this amount of subdivision, coverage is often sparse and sometimes non-existent. The source material for this atlas was obtained from the UK Meteorological Office archive of historical surface currents and this data set was compiled by the Institute of Oceanographic Sciences Deacon Laboratory (IOSDL).

  • This dataset consists of model outputs from ensemble simulations of an idealised Southern Ocean using a quasi-geotrophic model called Q-GCM. As such, there are no calendar dates associated with it. Two models were generated: Initial Condition Perturbation Ensemble (ICPE) experiments model output covers years 162-168 of the simulation; Boundary Condition Perturbation Ensemble (BCPE) experiments model output covers years 150-180 of the simulation. The models created form the practical element of the NERC project ‘The structure and stability of transport and fixing barriers within the Antarctic Circumpolar Current’. The project aims to quantify the relationship between Southern Ocean winds, the eddy saturation mechanism and the branch-like structure of the Antarctic Circumpolar Current. The work was funded by means of a Natural Environment Research Council (NERC) Discovery Science New Investigators Grant ‘NE/I001794/1’. The grant ran from 02 August 2010 to 21 September 2012 and was led by Dr. Chris Wilson at the UK’s National Oceanography Centre (NOC). The model simulation data were submitted to the British Oceanographic Data Centre (BODC) for archive and are stored in the originator format.

  • A set of underwater noise observations which provide information on noise levels over an 21 year period potentially setting a base line for future environmental monitoring. The data were collected for military operations by RAF Nimrod aircraft using air-deployed sonobuoys. They consist of averaged noise levels, measured in db, at a range of frequencies and depths throughout the UK Exclusive Economic Zone (EEZ).

  • 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. Data from the following sites are included in the data set: Holderness offshore (53 55.9N, 000 01.4E 01; Mar 1986 - 31 Mar 1987); Holderness nearshore (53 55.7N, 000 03.5W; 01 Mar 1986 - 30 Jun 1986); West Bexington (50 38.1N, 002 42.5W; 01 Nov 1983 - 31 Mar 1985; 01 May 1985 - 26 Feb 1986; 01 May 1986 - 30 Apr 1987); West Bexington (50 36.0N, 002 39.6W; 01 Sep 1987 - 01 Apr 1988); Eddystone (50 10.0N, 004 15.0W; 01 Jan 1976 - 31 Dec 1981); Kinnairds Head (57 55.8N, 001 54.1W; 01 Feb 1980 - 30 Dec 1981); Scilly Isles (49 51.8N, 006 41.0W; 01 Apr 1979 - 31 Jul 1979; 01 Feb 1980 - 31 Dec 1982; 01 Apr 1983 - 31 Dec 1983); South Uist deep water (57 17.8N, 007 53.6W; 01 Aug 1980 - 31 Dec 1982); South Uist offshore (57 18.2N, 007 38.3W; 28 Feb 1976 - 30 Nov 1982); South Uist inshore (57 19.8N, 007 27.2W; 01 Apr 1978 - 31 Jul 1982); Channel Lightvessel( 49 54.4N, 002 53.7W; 01 Mar 1986 - 30 Jun 1987; 01 Apr 1988 - 30 Nov 1988); Dowsing Lightvessel (53 34.0N, 000 50.2E; 01 Jul 1985 - 31 Dec 1985; 01 Feb 1986 - 30 Jun 1986; 01 Sep 1986 - 30 Apr 1987; 01 Jul 1987 - 31 Dec 1987); Ocean Weather Ship Lima (57 00.0N, 020 00.0W; 01 Jan 1984 - 30 Jun 1988; 01 Aug 1988 - 31 Dec 1988); Seven Stones Lightvessel (50 03.8N, 006 04.4W; 01 Jan 1985 - 28 Feb 1986; 01 May 1986 - 31 Mar 1987; 01 May 1987 - 31 May 1987; 01 Oct 1987 - 31 Oct 1987; 01 Dec 1987 - 31 Dec 1987). 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 WireWall project developed a prototype wave overtopping field measurement system. The system was designed and trailed at Crosby Beach, Hall Road carpark, north of Liverpool during winter 2018/2019. The data collected include both wave-by-wave overtopping volumes and horizontal velocities. At the time of the project the coastal structure at this site comprised a stepped revetment and vertical sea wall with a recurve. The system was designed at the National Oceanography Centre, validated in HR Wallingford’s flume facility and deployed with Sefton Council. Five datasets are available from the project. These contain processed data from: 1) The numerical wave overtopping estimates for past events used to design the system and plan deployments; 2) The numerical wave overtopping estimates for the joint wave and water level conditions with a 1 in 1 year return period probability to a 1 in 200 year return period probability in Liverpool Bay; 3) The dock side tests; 4) The physical laboratory experiments; and, 5) The field trials during windy spring tides. For Crosby these data can be used to validate/calibrate numerical tools used for coastal scheme design and flood hazard forecasting. Beach profile data collected alongside the overtopping measurements have been archived with the Northwest Regional Coastal Monitoring Programme, https://www.channelcoast.org/northwest/. This project was delivered by the National Oceanography Centre in collaboration with HR Wallingford. Our project partners were Sefton Council, Balfour Beatty, Environment Agency, Channel Coastal Observatory and Marlan Maritime Technologies.

  • The data set comprises 2193 profiles of turbidity from an area of the Severn Estuary (UK) between the Shoots and Bridgwater Bay between 1974 and 1978. The data were collected as analogue records of continuous vertical profiles on a time series cross-section basis, where possible, over 13.5 hours from a drifting ship. All measurements were collected between 0 m and 39 m depth. The data coverage is derived from 172 stations along 17 survey lines, the density of coverage varying between 1 and 99 records per station. Each analogue record was digitised as approximately 200 pairs of XY coordinates. The X ordinates were then converted to depth (in metres) using a depth calibration and the Y ordinates to parts per million (PPM) of sediment using siltmeter calibration data. The Fluid Mud data bank was designed by the (former) Institute of Oceanographic Sciences (IOS) Taunton, UK, and the data were originally stored at IOS on a PDP 11 computer. They were then moved to an Oracle RDBMS at the British Oceanographic Data Centre (BODC) and stored as the Bristol Channel Suspended Sediments Data Bank.
