The dataset details global positioning system (GPS) locations recorded for survey quadrats at six UK saltmarsh sites. Three of the sites were in Morecambe Bay, North West England and three of the sites were in Essex, South East England, each of these sites consisted of a salt marsh area and adjacent mudflat area. Each site comprised 22 quadrats on the unvegetated mudflat and 22 quadrats on the salt marsh. The locations indicated by this dataset correspond to the south-east corner of the quadrats which were 1m square and oriented with their sides aligned North-South and East-West. This data was collected as part of Coastal Biodiversity and Ecosystem Service Sustainability (CBESS): NE/J015644/1. The project was funded with support from the Biodiversity and Ecosystem Service Sustainability (BESS) programme. BESS is a six-year programme (2011-2017) funded by the UK Natural Environment Research Council (NERC) and the Biotechnology and Biological Sciences Research Council (BBSRC) as part of the UK's Living with Environmental Change (LWEC) programme.

The data set comprises temperature, pressure, position and occasionally wave data from nine drifting buoys that were deployed across the Southern Hemisphere. Data were collected from 1979 to 1981. Each buoy carried surface pressure and sea temperature sensors, and seven of the buoys were equipped with drogues in order to aid the study of large scale, near surface ocean currents, and to complement concurrent oceanographic observations made in the area by the research ship RRS Discovery. Two of the buoys were designed with good wave following characteristics and contained accelerometers and simple processors so as to yield good wave information. The buoys were equipped with UHF telemetry transmitters to relay data to the ARGOS system on board the polar orbiting meteorological satellites Tiros-9 and NOAA-6. The buoys were were deployed by the Institute of Oceanographic Sciences Wormley Laboratory UK as part of the First Garp Global Experiment (FGGE) Southern Hemisphere Drifting Buoy Network.

This data was collected during two Antarctic field seasons (2013-14, 2014-15) using two Leica GS10 dual-frequency Global Position Systems (dGPS). We installed 53 2m aluminium stakes in the snow surface along lines perpendicular to ice divides on four ice rises in the Ronne Ice Shelf region. In each season we used the dGPS units to measure the position of each pole. During most position measurements we deployed a rover unit for 20 minutes at each stake while a static base station dGPS unit was left in place for 5 or more hours. In the minority of cases the power to the base station unit failed and data from the rover unit is not accompanied by base-station data.

This dataset consists of measurements of underway meteorology, navigation and sea surface hydrography from RRS Discovery cruise DY072 in the Central Atlantic. Data from DY072 were collected between 28 Feb 2017 and 02 April 2017 along the Mid-Atlantic Ridge near the Chain and Romanche Fracture Zones. 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 for the duration of the cruise, excepting times for cleaning, entering and leaving port, and while alongside. This cruise formed the field component of NERC Discovery Science project ‘Passive Imaging of the Lithosphere Asthenosphere Boundary’ (PiLAB). The project aims to systematically image the entire length of an oceanic plate, from its birth at the Mid-Atlantic Ridge, to its oldest formation on the African margin, in order to determine the processes and properties that define and strengthen a plate. The Discovery Science project was composed of Standard Grant reference NE/M003507/1 as the lead grant with child grant NE/M004643/1. The lead grant runs from 01 February 2016 to 31 January 2019 and the child grant runs from 01 February 2017 to 31 July 2019, and is led by Dr Catherine A Rychart of University of Southampton, School of Earth and Ocean Sciences. Child grant NE/M004643/1 is led by Professor Michael Kendall of University of Bristol, Earth Sciences. 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 Discovery, processed and quality controlled using in-house BODC procedures and are available for download on the BODC website.

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.

The Carbon Uptake and Seasonal Traits in Antarctic Remineralisation Depth (CUSTARD) data set comprises hydrographic data, including measurements of temperature, salinity and currents, complemented by bathymetric, meteorological and nutrient data. All the observational data from the project were collected at, and south of, the Ocean Observatories Initiative (OOI) Global Southern Ocean Array, located south-west of Chile. Data collection activities span from November 2018 to January 2020 over 3 cruises (DY096, DY111 and DY112). The main aim of the CUSTARD project is to quantify the seasonal drivers of carbon fluxes in a region of the Southern Ocean upper limb, and estimate how long different quantities of carbon are kept out of the atmosphere based on the water flow routes at the observed remineralisation depths. The lead grant was funded by the NERC grant reference NE/P021247/1 with child grants NE/P021328/1, NE/P021336/1, NE/P021263/1. NE/P021247/1 was held at the National Oceanography Centre, led by Adrian Martin. Child grants were lead by Mark Moore of University of Southampton, Simon Ussher of University of Plymouth and Dorothee Bakker of University of East Anglia respectively.

The data set comprises of geophysical observations in the source regions of the 2004 and 2005 great Sumatra earthquakes. Geophysical surveys were carried out to determine the seabed bathymetry and underlying structure and geometry and included the collection of seismic reflection, magnetic, gravity, and sidescan sonar data. In addition, Conductivity-Temperature-Depth (CTD) and Sound-Velocity Probe (SVP) data were collected, as well as continuous meteorological (air pressure, air temperature, radiance, relative humidity, wind direction and speed) and sea surface (temperature and conductivity) data. Data were collected in the Indian Ocean, west and north west of Sumatra between 8 degrees South, 6 degrees North, 94 and 108 degrees East. The data were collected during three cruises, SO198-1, SO198-2 and SO200 over two legs SO200-1 and SO200-2. The three cruises took place between May 2008 and February 2009. The data collection focussed on the areas around two earthquake segment boundaries: Segment Boundary 1 (SB1) between the 2004 and 2005 ruptures at Simeulue Island, and Segment Boundary 2 (SB2) between the 2005 and smaller 1935 ruptures between Nias and the Batu Islands. Measurements were taken using a variety of instrumentation across all three cruises including: the long-term deployment of 50 Ocean-Bottom Seismometers (OBS) deployed on cruise SO198-1 and retrieved on cruise SO200-1; 154 Expendable Bathythermograph (XBT) probes; high resolution multichannel seismic reflection (MCS) profilers; Swath bathymetric and backscatter echosounders; SVPs and CTDs which were deployed simultaneously; and a gravity meter and Parasound sub-bottom profiler were operated continuously within the survey areas. In addition, sea surface and meteorological measurements were made using the underway system throughout the three cruises, although there are no data for days at the beginning and end of the cruises of up to 10 days. During the two legs of SO200 additional instrumentation was deployed including: a 30 kHz deep-towed sidescan sonar system (TOBI); piston cores and megacores collected along the plate margin; and heatflow probes long transects. The UK Sumatra Consortium project aimed to characterise the subduction boundary between the Indian-Australian plate and the Burman and Sumatra blocks (including subduction zone structure and rock physical properties), record seismic activity, improve and link earthquake slip distribution to the structure of the subduction zone and to determine the sedimentological record of great earthquakes (both recent and historic) along this part of the plate margin. The project will allow better assessment of future earthquake magnitudes and locations, and further the general understanding of the earthquake rupture process. The UK Sumatra Consortium project was led by the National Oceanography Centre Southampton (NOCS) and involved five UK partners; NOCS, the universities of Cambridge, Oxford and Liverpool, and the British Geological Survey as well as numerous international partners including French, German, American, Indonesian and Indian Collaborators. The principal investigator was Dr Timothy Henstock from NOC. The Natural Environment Research Council (NERC) funded data will be managed by the British Oceanographic Data Centre (BODC).
