  • This dataset consists of underway meteorology, navigation and sea surface hydrography measurements from cruise JC044 and JC082 as well as 7 CTD casts for cruise JC082. Data were collected on two RRS James Cook cruises, JC044 and JC082, covering the Cayman Trough and Mid-Cayman Spreading Centre in the Caribbean Sea. Cruise JC044 took place between March 25th and April 22nd 2010 and cruise JC082 took place between February 6th and March 8th 2013. Navigation data were collected using an Applanix POSMV system and meteorology and sea surface hydrography were collected using the NMF Surfmet system. Both systems were run through the duration of the cruise, excepting times for cleaning, entering and leaving port, and while alongside. CTD data were obtained from a Seabird SBE CTD system fitted to a rosette and launched at stations along the cruise track. Data were collected as part of the NERC-funded project “Hydrothermal activity and deep-ocean biology of the Mid-Cayman Rise” which aimed to investigate the world's deepest under-sea volcanic ridge, the Mid-Cayman Rise, to advance understanding of patterns of biodiversity in the planet's largest ecosystem. By studying the geology and hydrography of the world's deepest seafloor spreading centre using established techniques, the project aimed to confirm the geological processes driving the vents and to reveal the evolutionary genetic relationships of their inhabitants to those in vents elsewhere. The project was funded by two NERC standard grants. The lead grant, NE/F017774/1, ran from 15 September 2009 to 01 March 2014, and was led by principal investigator Dr Jonathan TP Copley of University of Southampton, School of Ocean and Earth Sciences. The child grant, NE/F017758/1, ran from 19 July 2009 to 31 December 2013, and was led by Dr BJ Morton of National Oceanography Centre, Science and Technology. Underway navigation, meteorology and sea surface hydrography and CTD datasets have been received as raw files by BODC and are available upon request.

  • An Alternative Framework to Assess Marine Ecosystem Functioning in Shelf Seas (AlterEco) will utilise a small fleet of submarine and surface autonomous vehicles combined with ongoing observational programmes to capture a seasonal cycle of physical, chemical and biological measurements on repeat transects over ~150km in the North Sea between November 2017 and January 2019. This dataset contains near real-time hydrographic measurements through the water column obtained from submarine Slocum gliders and Seagliders. The submarine vehicles have also been equipped with auxiliary sensors such as turbulence probes, nutrient sensors and acoustic sensors. Data from these platforms will be converted into the international 'Everyone's Gliding Observatories (EGO)' exchange format. This dataset will also contain measurements taken from CTDs deployed on eight cruises to provide calibration data for the autonomous vehicles. AlterEco involves collaboration between scientists at a number of organisations (National Oceanography Centre (NOC, lead), University of East Anglia (UEA), University of Liverpool (UoL), Plymouth Marine Laboratory (PML), Scottish Association for Marine Science (SAMS) and the Centre for Environment, Fisheries and Aquaculture Science (Cefas). In addition, there are a number of UK and international project partners.

  • The dataset comprises scanned images of historical analogue charts and data ledgers from eight tide gauge sites around the UK. The sites include: Sheerness, Belfast, and several sites around Liverpool managed by the Mersey Docks and Harbour Company namely, Eastham, Gladstone, Hilbre, Princes Pier, Tranmere and Waterloo. The Sheerness ledger data represents some of the earliest records of sea level data in the UK and cover the periods - January 1870 to December 1881, July 1882 to October 1894 and December 1929 to April 1941. Data availability for the other sites are: Belfast analogue charts - 27 November 1901 to 24 May 1902; Princes Pier ledgers: - 1941 to 1950, 1951 to 1960 and 1961 to 1970; Eastham, Gladstone, Hilbre, Princes Pier, Tranmere and Waterloo ledgers: - 1982 to 1988. The data recorded in some of the ledgers also describe meteorological measurements for example, air pressure, air temperature, wind speed and direction, and precipitation and evaporation. Funding to rescue these historical sea level data came from the Marine Environmental Data and Information Network (MEDIN) and the British Oceanographic Data Centre (BODC).These images have now been added to the National Oceanographic Database and are freely available to registered users (subject to licence agreement).

  • Macrofauna and polychaete species abundance data were obtained from replicate megacore samples collected from inside the Whittard Canyon (N.E. Atlantic) and the adjacent slope to the west of the canyon during cruise JC036 in June and July 2009. Four sites were sampled, three in the Whittard Canyon branches (Western, Central and Eastern) and one site on the slope to the west of the canyon. Five deployments were conducted in the Western branch, six in the Central and Eastern branches and five at the slope site. One extra deployment was made in the Central and Eastern branches to compensate for the failure to recover sufficient cores. All sites were located at 3500 m depth. Samples were collected using a Megacorer fitted with eight large (100 mm internal diameter) core tubes. Core slices from the same sediment layer from one deployment were pooled to make one replicate sample. The number of cores pooled per deployment ranged from 3 to 7 and the area of seabed sampled varied accordingly. The top three sediment horizons (i.e. 0–1, 1–3 and 3–5 cm), were analysed in toto. Macrofauna were identified to higher taxa levels, and polychaetes to species level and counts of species/taxa recorded for each site. AphiaIDs have been assigned to the samples - where identification was only possible to genus or family level, the aphiaIDs for genus and family have been supplied. The supplied aphaIDs are those that were acceptable at the time of the analysis and not their more recent superseding terms. This cruise was part of the HERMIONE project and the data formed the basis of L. Gunton's PhD thesis 'Deep-Sea Macrofaunal Biodiversity of the Whittard Canyon (NE Atlantic)'.

  • This dataset consists of measurements of underway meteorology, navigation and sea surface hydrography as well as underway discrete salinity samples. A comprehensive survey of the Tropical Atlantic was undertaken between June and August 2017. Data were collected on RRS James Cook cruise JC150. Navigation data were collected using an Applanix POSMV system and meteorology and sea surface hydrography were collected using the NMF Surfmet system. Both systems were run through the duration of the cruise, excepting times for cleaning, entering and leaving port, and while alongside. 65 salinity samples were taken from the non-toxic underway supply. The non-toxic, pumped seawater supply intake was located 5.5 m below the sea surface. Sample analysis was completed using a Guildline ‘Autosal’ salinometer. This cruise formed the field component of NERC Discovery Science project "Zinc, Iron and Phosphorus co-Limitation in the Ocean (ZIPLOc)". The data were collected in order to determine the prevalence of zinc and iron limitation of APA in the phosphate deplete subtropical North Atlantic Ocean; to quantify the impact of zinc-phosphorous and iron phosphorous co-limitation on biological activity, specifically phytoplankton growth, primary production and nitrogen fixation; and to quantify the significance of zonc-phosphorous and iron-phosphorous co-limitation in driving phytoplankton productivity over basin scales and multi-decadal time scales. The Discovery Science project was composed of Standard Grant reference NE/N001079/1 as the lead grant with child grant NE/N001125/1. The lead grant runs from 02 January 2017 to 03 February 2017 and the child grant runs from 01 February 2017 to 31 July 2019. Dr Claire Mahaffey of University of Liverpool, Earth, Ocean and Ecological Sciences was the principal investigator of the lead grant of this project. Prof Maeve C. Lohan of University of Southampton, School of Ocean and Earth Science was the principal investigator of the child grant. The underway discrete salinity samples data and the underway navigation, meteorology and sea surface hydrography data have been received by BODC as raw files from the RRS James Cook, processed and quality controlled using in-house BODC procedures and are will be made available online in the near future.

  • The World Ocean Circulation Experiment (WOCE) sea level data set comprises data collected from approximately 160 tide gauge sites distributed around the world. The data are usually hourly heights of sea surface elevation, although some were collected and supplied at higher frequencies (i.e. 6 or 15 minute intervals) or as pressure values rather than elevations. The data are primarily from 1990 to 1998 (the WOCE period), but the dataset also includes historical data as a number of the tide gauges had been operating for many years. The total volume of data held is 3550 site years. A few sites have data extending back over 50 years and many over 20 years. The British Oceanographic Data Centre (BODC) was responsible, as a WOCE Data Assembly Centre (DAC), for assembling, quality controlling and disseminating this comprehensive sea level data set. Data were supplied by Argentina, Australia, Canada, Chile, China, Cuba, Denmark, Ecuador, France, Iceland, Japan, New Zealand, Peru, Philippines, Portugal, Russia, South Africa, Spain, Ukraine, the UK and the USA. Data quality control was carried out with the aid of sophisticated screening software which allows rapid inspection of the data. The sea level data were tidally analyzed and the residuals inspected. Parameters other than sea level, for example atmospheric pressure and sea surface temperature, were also visually inspected. This quality control identified spikes and gaps in the data in addition to timing problems and datum shifts. Any problems identified were resolved with the data supplier. Qualifying information accompanying the data was also checked and data documentation assembled. The data can be downloaded from the BODC web site, or made available on CD-ROM.

  • The data set comprises time series of wave height and period data from in-situ wave recorders at fixed locations. Principal parameters are significant/characteristic wave height and mean zero crossing period - usually derived from the analysis of 20 or 30 minute recordings taken at intervals of the order of 3 hours. Data holdings include over 1500 recording months of data from some 60 sites across the continental shelf areas around the British Isles and the NE Atlantic between 1954 and 1995. Recording periods vary from 2 months at some sites to over 15 years. The longer series are noted here: Channel Lightvessel (49 54.4N, 002 53.7W; 01 Sep 1979 - 31 Dec 1985); Dowsing Lightvessel (53 34.0N, 000 50.2W; 01 May 1970 - 30 Apr 1971; 01 Nov 1975 - 30 Jun 1981; 01 Jan 1982 - 31 Dec 1982; 01 Jan 1984 - 31 Dec 1984); Ocean Weather Ship Lima (57 00.0N, 020 00.0W; 01 Jan 1975 - 31 Dec 1983); Saint Gowan Lightvessel (51 30.0N, 004 59.8W; 01 Aug 1975 - 31 Jul 1976; 01 Dec 1976 - 31 Dec 1983); Seven Stones Lightvessel (50 03.8N, 006 04.4W; 31 Jan 1962 - 31 Jan 1963; 01 Jan 1968 - 31 Dec 1969; 01 Jul 1971 - 30 Jun 1974; 01 Apr 1975 - 31 Dec 1985). The data originate primarily from UK and Irish 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 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.

  • This dataset consists of measurements of horizontal and vertical current velocity and of vertical profiles of temperature and salinity collected during cruise PE372 in the Bosphorus Strait and South West Black Sea, June and July 2013 . Pelagia cruise PE372 formed part of the field collection of project "Flow dynamics and sedimentation in an active submarine channel: a process-product approach" which was composed of NERC Discovery Science lead grant NE/F020511/1 and 2 child grants: NE/F020120/1 and NE/F020279/1
