  • This is a high resolution spatial dataset of Digital Surface Model (DSM) data in South West England. It is a part of outcomes from the CEH South West (SW) Project. There is also a Digital Terrain Model (DTM) dataset covering the same areas available from the SW project. Both DTM and DSM cover an area of 9424 km2 that includes all the land west of Exmouth (i.e. west of circa 3 degrees 21 minutes West). The DSM includes the height of features on the bare earth such as buildings or vegetation (if present). An overview of the TELLUS project is available on the web at http://www.tellusgb.ac.uk/. Full details about this dataset can be found at https://doi.org/10.5285/b81071f2-85b3-4e31-8506-cabe899f989a

  • This resource is the raw data from a topographic survey of the Sourhope field experiment site, conducted by the Department of Environmental Science, University of Stirling in April and May 2000. The data are available to match to other data sets from the field site, or to analyse in more detail. The data were collected as part of the NERC Soil Biodiversity Thematic Programme, centred upon the intensive study of a large field experiment located at the Macaulay Land Use Research Institute (now the James Hutton Institute)'s farm at Sourhope in the Scottish Borders (Grid reference: NT8545019630). During this time, the site was monitored to assess changes in above ground biomass production (productivity), species composition and relative abundance (diversity).

  • Historic sea level data from 6 sites on the South coast of England, recovered as part of a PhD on sea level trends in the English Channel. Devonport: 1961-1986, 1988-1990 Newhaven: 1942-1948, 1950-1951, 1953-1957, 1964-1965, 1973, 1988 Portsmouth: 1961-1990 Southampton: 1935-1979, 1982-1990 St. Marys: 1968-1969, 1973, 1975, 1977-1978, 1987-1989 Weymouth: 1967-1971, 1983-1987 There are raw data files and cleaned data files. The cleaned files have been corrected for datum changes which are recorded in the readme files for each site.

  • The data set comprises time series measurements from offshore pressure gauges mounted on the sea floor. The data holdings are approximately 100 observation months from 30 sites. The data are mainly from trans-ocean sections in the North Atlantic. Data records contain date/time, total pressure (or relative pressure) and, occasionally, temperature. The sampling interval is typically 15 minutes or hourly, over deployment periods ranging from 1 to 6 months. Data were collected mainly by the Proudman Oceanographic Laboratory (POL), now the National Oceanography Centre (NOC) at Liverpool, and are managed by the British Oceanographic Data Centre (BODC).

  • A large number of charts (originals and copies) together with tabulations of data are also available, some of which date back to the 1850s. A more detailed description of these will be available once they have been systematically catalogued and archived.

  • Historical sea level data for the Thames region. These data were originally screened as part of an Environment Agency project on extreme sea level in the Thames estuary. Coryton: 1966-1970, 1973-1974 North Woolwich: 1950, 1955-1963, 1965-1967, 1969-1970, 1973-1974 Southend: 1981-1983 Tilbury: 1931-1945, 1960-1961, 1967, 1970, 1984 Tower Pier: 1928-1942, 1944-1945, 1947-1951, 1954-1955, 1958, 1960-1966, 1973

  • The data set comprises time series of sea level data from coastal tide gauges. The data holdings include over 1000 site years of data from about 200 sites comprising about 10 million records. About 75 per cent of the data are from some 100 sites around the British Isles - the remaining data are from coastal sites and islands scattered across the globe. Data are primarily hourly values. Recording periods vary from one month at some sites to over several years.There are three short series from around the Irish coast which were collected in 1842.

  • The UK national network of sea level gauges was established after violent storms in the North Sea in 1953 resulted in serious flooding in the Thames Estuary. The data are required for research and operational use and to facilitate specific scientific studies of coastal processes such as tidal response, storm surge behaviour and sea level rise; and for underpinning local and national operational systems such as the Storm Tide Forecasting Service at the Met Office. BODC has a special responsibility for the remote monitoring and retrieval of sea level data from the network. Daily checks are kept on the performance of the gauges and the data are downloaded weekly. These are then routinely processed and quality controlled prior to being made available.

  • 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.

  • The Mediterranean-Alpine Experiment (MEDALPEX) data set comprises over 200,000 hourly sea level measurements. Data are included from 28 sites around the northern coast of the Mediterranean and one in the Atlantic at Cadiz. Measurements were collected from December 1981 and September 1982, with a special observing period (SOP) between 15 February and 30 April 1982. Twenty eight coastal sites were instrumented with conventional stilling wells, while one offshore site off Corsica used a bottom pressure recorder. The data are stored, together with benchmark information, as time series at each site with hourly values of sea surface elevation recorded to the nearest millimetre. The aim of the MEDALPEX Experiment was to study the role of atmospheric forcing on the dynamics of the Western Mediterranean. Data were supplied by laboratories in Belgium, France, Monaco, Italy, Spain, UK and former Yugoslavia. Responsibility for assembling, quality controlling and analyzing the sea level data collected during MEDALPEX was vested in the British Oceanographic Data Centre (BODC).
