This dataset is comprised of CTD temperature, salinity and potential temperature collected using seal tags. Data were collected as part of the NERC-funded project 'Ocean processes over the southern Weddell Sea shelf using seal tags'. Data were not collected as part of a cruise as seals were used as data activity platforms. 20 Weddell seals were tagged at the eastern end of the shelf-break north of the Filchner-Ronne Ice Shelf between 11 February 2011 and 03 May 2011. The aims of the project were: 1. The resulting data from the seals’ dives will provide the most comprehensive picture to date of the ocean conditions over the southern Weddell Sea continental shelf. 2. By mapping the temperature of the water near the sea floor it will be possible to determine the locations where dense waters leave the shelf, and the processes involved: either a direct flow down the slope under gravity, or initially mixing at the shelf edge with waters from off the shelf before descending down the slope. 3. To determine where the source waters come onto the shelf. 4. Though the research was primarily oceanographic, the movements and diving behaviour provide insight to seal biologists studying the animals' beahviour. Data were collected as part of NERC standard grants NE/G014086/1 and NE/G014833/1. NE/G014086/1 was the lead grant and was led by Dr Keith William Nicholls of NERC British Antarctic Survey, Science Programmes and runs from 01 April 2010 to 31 December 2018. The secondary grant, NE/G014833/1, was led by Professor Michael Fedak of University of St Andrews, Sea Mammal Research Unit and runs from 01 October 2010 to 28 February 2014. The seal tag CTD data have been received by BODC and are currently available in original format upon request.

Sea surface temperature and salinity data have been collected around British coastal waters and in the North Atlantic between 1963 and 1990. The data were collected by ships regularly plying routes between ports in the British Isles and the Continent, and along routes to the North Atlantic Ocean Weather Stations (OWS). Thirty individual shipping routes have been involved, approximately weekly measurements being taken at intervals ranging from 10 to 50 miles depending on the route. The following list details shipping routes and dates of data collection: Bristol - Finistere (Jan 1963 - Nov 1968); Clyde - OWS Alpha (May 1963 - Feb 1974); Clyde - OWS India (Jan 1963 - Jul 1975); Clyde - OWS Juliet (Jan 1963 - Jul 1975); Clyde - OWS Kilo (Mar 1963 - Dec 1972); Clyde - OWS Lima (Mar 1963 - May 1965, Jul 1975 - Dec 1990); Felixstowe - Rotterdam (Aug 1970 - Dec 1990); Fishguard - Cork (Jan 1963 - Oct 1968); Fishguard - Waterford (Jan 1963 - Dec 1966); Folkstone - Boulogne (Jan 1963 - Aug 1966); Heysham - Belfast (Feb 1965 - May 1977); Holyhead - Kish (Jan 1963 - Feb 1966); Hull - Kristiansand (Jan 1963 - May 1976); Larne - Stranraer (Jan 1963 - Feb 1966, Jan 1971 - Dec 1986); Leith - Bremen (Jan 1963 - Apr 1972); Leith - Copenhagen (Jan 1963 - Mar 1968); Liverpool - Belfast (Dec 1970 - Nov 1978); Liverpool - Douglas (Mar 1965 - Nov 1968); Liverpool - Dublin (Mar 1965 - Aug 1979); Liverpool - Larne (Jan 1987 - Dec 1988); Newhaven - Dieppe (Apr 1963 - Feb 1990); Scilly - Shamrock (May 1967 - Mar 1974); Southampton - Le Havre (Jan 1963 - May 1964); Southampton - St. Malo (May 1963 - Sep 1964); Swansea - Cork (May 1970 - Mar 1979); Weymouth - Channel Islands (Nov 1970 - Nov 1985); Weymouth - Cherbourg (Apr 1986 - Sep 1986); Whitehaven - Anglesey (Feb 1965 - Jan 1969). These observations provide useful information on the seasonal and short-term variability of temperature off-shore, and may enhance our knowledge regarding extreme values. The data were collected on behalf of the Ministry of Agriculture, Fisheries and Food, Lowestoft Fisheries Laboratory and are stored at the British Oceanographic Data Centre.

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.

A novel temperature dataset for northern high latitude Seas (ATLAS) is a dataset of three-dimensional temperature derived from combining quality controlled Argo float measurements with marine mammal mounted Satellite Relay Data Loggers (SRDLs) profiles. Using data values gathered from across the North Atlantic region, a 1×1 degree gridded temperature dataset of the average monthly values from January 2004 to December 2008, with 15 vertical layers between 0–700 m was produced. Built as complementary to existing ship-based fields, the ATLAS dataset is a community resource to help determine the impacts of climate change on the Labrador and Nordic Seas regions. The data were collated by the National Oceanography Centre (NOC) and are made available from the British Oceanographic Data Centre (BODC).

This dataset contains Radium (Ra) and Iron (Fe) concentrations along with supporting oceanographic measurements such as temperature and salinity of the water column. Data are from glacial melt waters around the West Antarctic Peninsula and Greenland as well as from the open southern ocean and at hydrothermal vents along the Mid-Atlantic Ridge. The data were collected for the Radium in Changing Environments: A Novel Tracer of Iron Fluxes at Ocean Margins (RaCE:TraX) project. The RaCE:TraX project is running between June 2017 and June 2022 and uses measurements of Radium (Ra) and Iron (Fe) along with knowledge of the half-life of Ra to predict supply and removal rates of Fe in the marine environment. The results hope to answer the questions 1) how much Fe comes from continental shelf sediments, 2) how much Fe is supplied by glacial meltwater, and 3) how rapidly is Fe scavenged from the metal-rich fluids at hydrothermal vents? Addressing these key gaps in the understanding of the marine Fe cycle will help determine how sensitive marine systems are to current Fe supply, as well as predict the impacts of changes in Fe supply on phytoplankton health, the biological pump, and global climate. The project is led by the University of Southampton School of Ocean and Earth Science and is a collaboration with the University of Bristol. The project received funding from the Natural Environmental Research Council (NERC, grant reference number: NE/P017630/1).

The North Atlantic Norwegian Sea Exchange (NANSEN) data set comprises hydrographic profiles (temperature and salinity) and time series of current velocity, temperature and occasionally conductivity from the North Atlantic Ocean. The measurements were collected between 1986 and 1988 using conductivity-temperature-depth (CTD) profilers, moored current meters and thermistor chains. Data collection was undertaken by six laboratories in four countries (Faroes, Germany, Norway and the UK). The NANSEN project was conceived by the International Council for the Exploration of the Sea (ICES) Oceanic Hydrography Working Group. It aimed to study the hydrography and circulation of the Iceland Basin and the temporal and spatial variability of the inflows and outflows across the Greenland-Scotland Ridge. Current meter data from a number of laboratories involved in NANSEN and CTD data collected by UK participants are managed by the British Oceanographic Data Centre (BODC). A further 50 current meter series have been collected, but have not yet been acquired by BODC. The data will be subjected to the usual BODC quality control procedures for current meter series. The hydrographic data set collected during the NANSEN experiment has been compiled by the ICES Secretariat.

This dataset contains measurements of temperature, salinity, raised/non-raised mackerel egg numbers, raised/non-raised horse mackerel egg numbers as well as adult fish total length, weight, maturity and sex. Data were obtained on the RV Bjarni Sæmundsson which sampled North of Scotland to Iceland. The project altogether obtained data along the Portuguese coast from February and continued until July to the waters west of Scotland. The egg survey was carried out from the 02/05/2016 to 13/05/2016 with the adult mackerel sampling taking place on 11/05/2016. A total of 4 pelagic trawl hauls were carried out to collect adult mackerel samples using a pelagic WB trawl. Sampling of the fish eggs was carried out with a High Speed Plankton Sampler Gulf VII, which had a 280 micron mesh sized net and an opening diameter of 20cm. A small skrips-depressor of 30 kg was also attached to the sampler. Water filtered during each haul was measured using an internal Valeport electronic flowmeter. An external flowmeter was in turn mounted on the frame, as well as a Seabird 911 plus CTD attached with an altimeter, which measured depth, temperature and salinity. Samples were sorted for fish eggs using the spray method and mackerel eggs were staged according to the sampling protocol. For quality assurance, 10% of the samples were checked and sorted again. All eggs were counted and identified to species level. The data were obtained as a part of an international Atlantic survey, carried out by 10 different European institutes to monitor the spatial and seasonal distribution of Atlantic mackerel and horse mackerel. Planning and coordination of the survey was made within the ICES Working Group for Mackerel and Horse Mackerel Egg Surveys (WGMEGS). In 2016 the following countries participated in this survey: The Faroes, Denmark, Germany, Ireland, Norway, Portugal, Scotland, Spain, the Netherlands and Iceland. The data present here has been obtained by Marine Research Institute in Iceland.

This document describes CTD data collected on three cruises undertaken within the Dogger Bay Bank between August and November 2004, the RV Endeavour 12/04 (September 30 – October 10), 13/04 (August 31 – September 04) and 14/04 (October 22 – November 01). Ship-deployed CTDs were used to collect data at stations throughout each of the cruises. The cruises formed the research component of CEFAS project A1225 – North Sea Dogger Bank. This project is aimed at achieving a better understanding of the dynamics of the circulation processes of the seas around the UK, in order to characterise the extent and nature of density driven and seasonal jet-like circulation which acts as a direct and rapid pathway for transport of material. This project was conducted by the Centre for Environment, Fisheries and Aquaculture Science (CEFAS), Lowestoft Laboratory, led by Dr. Stephen Dye. The CTD data have been received by BODC as raw files from the RV Endeavour, processed and quality controlled using in-house BODC procedures and are available online to download from the BODC website.

The Drake Passage is a hydrographic section, occupied almost annually since 1993, consisting of full-depth CTD stations and lowered and shipboard Acoustic Doppler Current Profiler measurements. It is occupied annually to detect changes in the Antarctic Circumpolar Current (ACC) and variability of the ocean transport. The standard section includes measurements of the physical properties of the ocean, i.e. temperature, salinity and currents. The Drake Passage section lies on a satellite ground track with the northern end on the south side of Burdwood Bank, south of the Falkland Islands, and the southern end off Elephant Island at the tip of the Antarctic Peninsula. The data have been collected in months between November and February, since 1993 (with the exception of 1995/96 and 1998/99). Measurements were taken using conductivity temperature depth (CTD) profilers and Acoustic Doppler Current Profilers (ADCPs). The Drake Passage provides the link between the Pacific and Atlantic Oceans, as it constricts the ACC to a narrow geographical region, which makes this the best place to measure its properties. The Drake Passage is a series of sustained observations which are taken to identify small changes in the ACC. The work was initially led by scientists from the Institute of Oceanographic Sciences at Wormley, and more recently by teams from the National Oceanography Centre at Southampton. The main partners have been from NERC's British Antarctic Survey. Data, from the section, are held at the British Oceanographic Data Centre.

The dataset consists of temperature, salinity and sea surface height data generated from a 40 year run of the Proudman Oceanographic Laboratory Coastal Ocean Modelling System (POLCOMS) numerical model. The dataset consists of 41 data files in Climate and Forecast (CF) compliant NetCDF format. The data are supplied as a gridded dataset covering the entire northwest European continental shelf and extending out into the Atlantic Ocean. The grid resolution varies from 7.8 km to 14.2 km along the longitudinal axis and is at 12.3 km on the latitudinal axis. The model contains 40 depth layers. The model run was from 01 January 1964 to 31 December 2004 and the generated data were averaged over a 25 hour tidal cycle to create daily mean values. The data were generated from the Proudman Oceanographic Laboratory Coastal Ocean Modelling System (POLCOMS) numerical model. The model simulations were run on the HECTOR supercomputer managed by the University of Edinburgh. The dataset was generated to look at multi-decadal variability and trends in temperature of the northwest European continental shelf. The data were generated by the National Oceanography Centre (NOC) Liverpool as part of Natural Environment Research Council (NERC) National Capability (NC) funding.
