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.

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 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' behaviour. 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 ran 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 ran 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.

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 multi-decadal time series initially contains water current and temperature data from a single, near bottom instrument. A second, shallower instrument recording the same parameters was subsequently added after several years of successful operation. Conductivity data are similarly integrated into the time series after a further period of operation. The data are typically at hourly resolution. The mooring is situated in the Tiree Passage, between the Isles of Mull and Coll, off the west coast of Scotland. The specific site chosen was where the passage is at its narrowest (10 km), mid-way between the coasts of the two Isles. The mooring site is in water depths of approximately 45 m. Mooring activity began in June 1981 and consisted of a single RCM current meter placed 11 m above the seabed. The mooring design was modified to incorporate a second RCM current meter at 22 m above the seabed from November 1987. Aanderaa conductivity sensors were added at the two depths in 1993, with MicroCAT conductivity sensors being incorporated in 2002. There are some gaps in the record, most noticeably between January 2000 and May 2002, a period when the observations were temporarily suspended. Fishing damage has generated smaller gaps in the data set over the years. This region was chosen as a site for long term monitoring after radiocaesium studies showed that the major part of the water carried northwards from the North Channel in the Scottish coastal current passes between Mull and Coll. The mooring provides data for comparison with tracer studies and for an examination of the roles of wind forcing and buoyancy contributions to the coastal current. Tiree Passage mooring work is led by Colin Griffiths at the Scottish Association for Marine Science (SAMS).

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 dataset comprises of vertical profiles of water column properties (temperature, salinity, conductivity, pressure, depth, sound velocity and density) of the full water column in the South West region of the UK. Measurements were taken opportunistically at three main locations (L4, L5 and E1 Western Channel Observatory stations) as well from Plymouth Sound and the surrounding inshore areas. Data have been gathered using a Valeport MIDAS 606 CTD (with a passive flow induction cell, Platinum Resistance Thermometer and a strain gauge transducer) and extracted and processed using Valeport DataLogX2 software (version1.0.4.1270). The CTD was deployed using vertical deployment from the RV MBA Sepia and were hauled using a manually controlled hydraulic winch. The surveyors have been dependent on the sensor calibrations applied by the CTD manufacturer (Valeport). Manufacturer calibrations are applied to the in situ direct measurements via sensor specific microchips in the CTD unit. Derived parameters are calculated using the in-built processing provided with the units software: Datalogx2. The data have been collected in the framework of the long term monitoring of the Western Channel Observatory stations and the Plymouth inshore fisheries undertaken annually by the Marine Biological Association of the United Kingdom. The RV MBA Sepia department of the Institute carried out the data collection activities.

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

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 comprises of vertical profiles of water column properties (temperature, salinity, conductivity, pressure, depth, sound velocity and density) of the upper ocean (up to 500m) from 6 locations around St Helena Island. The locations were repeat sampled monthly over 22 months between December 2017 and September 2019, with opportunistic profiles taken from the two main seamounts (Bonaparte and Cardno complex) and the surrounding open ocean. Each individual cast, with up and down profiles, is contained in a separate .csv file. The file naming follows this schema: YYYYMM_stationname. An additional .csv file is provided with details of each serial number and CTD cast (with date, station names also included). Data have been gathered using a Valeport mini CTD (with a passive flow induction cell, Platinum Resistance Thermometer and a strain gauge transducer) and extracted using Valeport DataLogX2 software (version1.0.4.1270). The CTDs were deployed using vertical deployment from a 12m vessel and were hand hauled. No calibration has been applied when using the Valeport mini-CTD with acetal housing and have been supplied to BODC in raw format. The surveyors have been dependent on the sensor calibrations applied by the CTD manufacturer (Valeport). The data have been collected in the framework of the Darwin PLUS Initiative project 'Oceanographic influences on the St Helena pelagic ecosystem' (reference number 070). The data collection activities were carried out by the Government of St Helena with additional collaboration from the British Antarctic Survey (BAS), the Centre for Environment, Fisheries and Aquaculture Science (Cefas), and the International Commission for the Conservation of Atlantic Tunas (ICCAT). As part of the blue-belt initiative, St Helena was planning to declare a Category VI Sustainable use MPA in the entire maritime zone in early 2017. A key-part of ensuring sustainability is to understand the pelagic ecosystem and how seasonal or long-term changes in that system will impact the abundance and distribution of the whale sharks and fish on which the economy of the island depends. The Darwin project wanted to address key priorities including (i) improving conservation and management of the marine environment (ii) developing ecosystem approaches to marine management (iii) promoting sustainable fisheries and (iv) developing data systems on biodiversity.
