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. We combined spatial data relating to the environs of the study sites from a number of sources (Ordnance Survey Digital Terrain Models, Ordnance Survey Boundary Line, Environment Agency Saltmarsh Extents, Natural England Priority Habitat Inventory). These were rasterised and quadrat values were extracted on a pointwise basis for elevation and proximity (distance to creek, habitat edge and high water mark). Tidal height was calculated with reference to the relevant Tidal Gauge and Admiralty Standard Port information. This data was derived 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.

This is a high resolution spatial dataset of Digital Terrain Model (DTM) data in South West England. The DTM along with a Digital Surface Model (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 DTM represents the topographic model (height) of the bare earth. The dataset is a part of outcomes from the Centre for Ecology & Hydrology South West (SW) Project. There is also a Digital Surface Model (DSM) dataset covering the same areas available from the SW project.

Spot heights (elevation values in metres) for areas within the Plynlimon catchments; digitised from scanned topographic maps of Plynlimon Catchment Areas.
Elevation contour lines within the Severn catchment at 10 metre intervals. Digitised from the scanned topographic maps.
Hydrologically corrected digital terrain model (DTM) of Plynlimon catchments. The DTM was derived from digitised elevation data from scanned topographic maps.
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/.

Elevation contour lines within the Wye catchment at 10 and 20 metre intervals. The contour lines have been digitised from a scanned topographic map.
The 26 North dataset comprises moored temperature, conductivity and salinity, current velocity, acoustic travel time and bottom pressure time series. Data have been collected in the North Atlantic between latitudes of 23.7 degrees N and 28 degrees N in three sub -arrays at the Western Boundary (76.9 degrees W to 69.4 degrees W), Mid-Atlantic Ridge (52.1 degrees W to 40.9 degrees W) and Eastern Boundary (24.2 degrees W to 12.2 degrees W ). A number of instrumented moorings, some of which are full depth, have been deployed in each sub-array. Data have been collected since February 2004 and the moorings have been turned around every year. Data have been collected using a variety of moored instrumentation including conductivity-temperature-depth (CTD) sensors, current meters, Bottom Pressure Recorders (BPR), Inverted Echo Sounders (IES) and Acoustic Doppler current profilers (ADCPs). Data are collected in order to calculate and continuously monitor the Meridional Overturning Circulation (MOC) and provide a long term time series of the strength of the MOC. The 26 North dataset comprises moored data collected by the RAPID: monitoring the Atlantic Meridional Overturning Circulation at 26.5 degrees N since 2004 (RAPIDMOC) project and the Meridional Overturning Circulation and Heat-flux Array (MOCHA) project. Data are held at the British Oceanographic Data Centre.
The dataset comprises 1 hydrographic data profile, collected by a conductivity-temperature-depth (CTD) sensor package, from across the Inner Seas off the West Coast of Scotland area specifically Loch Shieldaig during August 2006. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Fisheries Research Services Aberdeen Marine Laboratory.
The RAPID-MOCHA-WBTS dataset comprises measurements of current velocity, temperature, salinity and pressure. Oceanic volume transports are calculated from these variables resulting in continuous measurements of the Atlantic Meridional Overturning Circulation (AMOC). Data collection is obtained from a mooring array across 26.5N in the Atlantic Ocean and cable measurements across the Florida Straits. The measurement array extends from the Bahamas to the African coast. The data have been measured continuously between April 2004 and September 2018. The data are collected periodically (currently every 18 months) from various UK and USA research cruises. Measurements between the Bahamas and Africa were made using a variety of MicroCat CTD sensors, various current meters and ADCP. All instruments are located on 18 moorings in various locations at 26.5N. An undersea cable makes current velocity measurements across the Florida Straits. The RAPID-MOCHA-WBTS programme aims to deliver a multi-decadal time series of observations of AMOC. The observations will be used with data from other sources to determine and interpret recent changes in the AMOC, to assess the risk of rapid climate change due to changes in the MOC, and to investigate the potential for predicting the MOC and its impacts on climate. The RAPID-MOCHA-WBTS programme is a joint effort between NERC in the UK (the UK Principal Investigator is David Smeed), NOAA (Molly Baringer) and RSMAS (Prof. Bill Johns) in the USA. The Atlantic MOC transport (and its components), calculated from the above data, and gridded files of temperature and salinity are held by BODC in NetCDF format.
