  • 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).

  • This dataset consists of eastward and northward current components at 32 depth levels. The dataset is a gridded dataset, with grid resolution of 1.85 km. It covers the entire Irish Sea area, with a precise range from -2.7 degrees longitude to -7 degrees longitude and from 51 degrees latitude to 56 degrees latitude. The data are daily averages and cover the period from 01 January 1996 to 01 January 2007. The dataset was generated by the Proudman Oceanographic Laboratory Coastal Ocean Modelling System coupled with the Wave Modelling model (POLCOMS-WAM) as part of the Natural Environment Research Council (NERC) CoFEE project which ran from April 2007 to September 2010. The eastward and northward current components were used as input conditions into a coastal processes and sediment transport model which looked at the response of the north Liverpool coastline to extreme flooding events. The dataset was generated by the Proudman Oceanographic Laboratory (since April 2010, part of the UK National Oceanography Centre). The dataset consists of 132 data files in Climate and Forecast (CF) compliant NetCDF format.

  • The LOCATE (Land Ocean CArbon TransfEr) project in the UK consists of measurements of dissolved organic carbon (DOC), nutrients, temperature, salinity, alkalinity and sediment in rivers and estuaries combined with a terrestrial model to predict the future evolution of the land ocean carbon flux. LOCATE samples identify the amount of organic carbon, washed from soils, enters the oceans, with emphasis on estuaries and coastal waters. The LOCATE project integrates knowledge and skills across NERC terrestrial, freshwater and marine research centres to transform the UK’s ability to measure, model and predict land-ocean fluxes in a changing environment. LOCATE is a collaboration between the National Oceanography Centre (NOC), the Centre for Ecology and Hydrology (CEH), the British Geological Survey (BGS) and the Plymouth Marine Laboratory (PML). LOCATE is funded by the Natural Environment Research Council (NERC) from 2016 until 2021. The estuarine and oceanographic data are held by the British Oceanographic Data Centre (BODC), the river data are held by the Environmental Information Data Centre (EIDC).

  • The dataset consists of 2580 tiff images of tide gauge charts from Bowling, River Clyde. The images were taken from annual bound volumes of tide gauge charts (~1 page per week, 52 pages per volume). A typical volume measures 37 x 34 x 3.5 cm and pages are single sided. The ledgers for Bowling begin in 1888 and end in 1952, but under this project, only the charts up until 04/01/1939 were photographed. The trace on the original charts was generated by a float tide gauge. The float inside a stilling-well was connected by a wire run over pulleys to a pen that moved up and down as the tide rose and fell. The images were generated by a commercial scanning organisation (TownsWeb Archiving Ltd) using a planetary overhead book scanner. In July 2016 The Peel Group Ltd. (Glasgow) approached BODC to donate their tidal archive, due to office redevelopment. The archive consists of ledgers of tide gauge charts (345 annual bound volumes) and handwritten ledgers (91 bound books) from several locations along the Clyde, with the earliest record beginning in 1841 from Glasgow Harbour. Later that year BODC received a grant from the Marine Environmental Data and Information Network (MEDIN) to photograph a selection of the ledgers. MEDIN released these funds to support small Data Archiving Projects that increase access to industry marine data. Ledgers also exist for Broomielaw, Dalmuir, Gourock, Govan Wharf, Greenock, Partick Wharf Glasgow, Queen's Dock Entrance Glasgow and Rothesay Dock. Most begin in the late 19th Century and run to the mid-20th century. It is hoped that these will be digitised in the future, subject to funding.

  • 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.

  • Monthly output from an integration of the UK Global Ocean, GO6, configuration of the NEMO (Nucleus for European Modelling of the Ocean) ocean and sea-ice model, forced by the JRA-55 (Japanese 55-year atmospheric reanalysis: Tsujino, 2018) surface field dataset. GO6 consists of version 3.6 of NEMO and version 5.2.1 of the CICE (Community Ice CodE) sea-ice model, and the present simulation is on the global eORCA025 1/4° grid. The ocean is initialised from a climatology based on the EN3 monthly objective analysis (Ingleby and Huddleston, 2007) averaged over years 2004–2008, and is integrated from 1958 to 2020. The sea-ice fields are only available for the period 1989 to 2001. The model was run on the Archer supercomputing platform through the Rose/Cylc interface on Puma, and the run ID on the Puma system is u-ba494. The integrations were funded by the Natural Environment Research Council (NERC) under the Atlantic Climate System Integrated Study (ACSIS) project (NE/N018044/1).

  • This CD-ROM set contains the volume 1 Snow, Ice, and Oceans data collection. The data covers a 24 month period, 1987-1988, and all but one are mapped to a common spatial resolution and grid (1 degree x 1 degree). Temporal resolution for most datasets is monthly; however, a few are at a finer resolution (e.g., 6-hourly). This dataset contains data covering: *Global snow depth *Sea surface temperature *Weekly Northern Hemisphere snow cover *NMC/ECMWF Reanalysis sea ice

  • The data set consists of bathymetric contours, at 100m intervals, from a depth of 100m to 5000m. The data were digitised from two charts of the Northeast Atlantic compiled by geoscientists at the Institute of Oceanographic Sciences (IOS), Wormley, Surrey and published by the UK Hydrographic Office, Taunton. Admiralty Chart C6566: Bathymetry of the northeast Atlantic (IOS Sheet 1) - 'Reykjanes Ridge and Rockall Plateau' by A.S. Laughton, D.G. Roberts & P.M. Hunter published in February 1982 and covering the area (47° to 64°N, 13° to 37°W). Admiralty Chart C6567: Bathymetry of the northeast Atlantic (IOS Sheet 2) - 'Continental Margin around the British Isles' by D.G. Roberts, P.M. Hunter & A.S. Laughton published in February 1977 and covering the area (47° to 64°N, 6°E to 18°W). The data set is included in the Centenary Edition of the GEBCO Digital Atlas (GDA) as sheet G.02. Please note that within the GDA data set some areas covered by sheets IOS sheets 1 and 2 have been replaced by higher resolution data sets. Through the GDA software interface the data may be exported in ASCII or shapefile format.
