  • This dataset comprises 39 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in July 2008 from stations in Liverpool Bay and Eastern Irish Sea. 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 Proudman Oceanographic Laboratory as part of the National Oceanography Centre (formerly the Proudman Oceanographic Laboratory), Liverpool Bay/Irish Sea Coastal Observatory initiative.

  • The RAPID-AMOC (Rapid Climate Change - Atlantic Meridional Overturning Circulation) data set consists of pressure, current velocities, temperature, salinity, density, oxygen, alkalinity, pH, PCO2 and inorganic carbon time series. Measurements are collected by moored instruments deployed in arrays across the Atlantic at approximately 26.5N for the Monitoring the Atlantic Meridional Overturning Circulation at 26.5N (MOC) project and the Atlantic BiogeoChemical Fluxes (ABC Fluxes) project. The data set also consists of conductivity- temperature-depth (CTD) profiles, and ships' underway monitoring system meteorology and surface hydrography collected during the mooring deployment and servicing cruises. The RAPID-AMOC data set follows on from the original Rapid Climate Change (RAPID) Programme oceanographic dataset and the RAPID-WATCH dataset. It spans data collected from 2015 to the present and is intended to continue to collect data until approximately 2020. The main aims of the RAPID-AMOC Programme are to provide oceanographic measurements that continue the long time series of the Atlantic Meridional Overturning Circulation to be derived for use in climate change research. The MOC and ABC Fluxes projects are led by scientists at the National Oceanography Centre in Southampton.

  • The dataset comprises 25 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North Sea area specifically along the east coast of Scotland and the Moray Firth to the Firth of Forth, during May of 1993. 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 Scottish Office Agriculture and Fisheries Department Aberdeen Marine Laboratory.

  • The dataset comprises 24 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, within the North East Atlantic Ocean area, incorporating the Dunstaffnage Marine Laboratory Rockall via Anton Dohrn (Ellett Line) section from east of the seamount to Rockall, plus a north-south section over the seamount. The data were collected during May of 1982. 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 Scottish Marine Biological Association.

  • The dataset comprises 242 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North East Atlantic Ocean (limit 40W) area specifically the Iberian shelf and shelf edge during August 1994. 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 University of Wales, Bangor School of Ocean Sciences.

  • The dataset comprises 61 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North Atlantic Ocean, Inner Seas off the West Coast of Scotland and the Irish Sea and St. George's Channel areas specifically to the West of Scotland and the NW of Ireland, during November and December of 1999. 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.

  • This dataset consists of measurements of underway meteorology, navigation and sea surface hydrography, sound velocity profiles, gravimetrics, swath bathymetry and seismic activity in the Mid-Atlantic Ridge. Data were collected by RRS James Cook cruises JC102 (06 – 18 April 2014), JC109 (11 October to 5 November 2014) and JC132 (14 January to 24 February 2016). The data were collected in the Mid-Atlantic Ridge as part of an investigation into the role and extent of detachment faulting at slow-spreading mid-ocean ridges. Sound velocity profiles were created using a Valdeport midas sound probe deployed once on each cruise. Gravity data were collected using a Lacoste_Romberg air-sea gravimeter. 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 cruises, excepting times for cleaning, entering and leaving port, and while alongside. Swath bathymetry data were collected using a Kongsberg EM-120 multibeam echosounder, which was run throughout the duration of each cruise. These cruises formed the field component of NERC Standard Grant project "Role and extent of detachment faulting at slow-spreading mid-ocean ridges". Data were collected with the aim to determine (1) the sub-surface geometry and extent of the detachments beneath the ridge axis, (2) the amount and detailed distribution of magmatic crust, and (3) the asymmetry of spreading rates associated with oceanic core complexes and the volcanic seafloor. The Discovery Science project was composed of Standard Grant reference NE/J022551/1 as the lead grant with child grants NE/J02029X/1, NE/J021741/1. The lead grant, NE/J022551/1, runs from 01 April 2013 to 31 December 2019, and is led by Professor Timothy Reston, University of Birmingham, School of Geography, Earth and Environmental Sciences. Child grant NE/J02029X/1 runs from 01 March 2014 to 31 January 2019 and is led by Professor Christine Peirce, Durham University, Earth Sciences. Finally, child grant NE/J021741/1 runs from 01 January 2014 to 31 December 2018 and is led by Professor Christopher John MacLeod, Cardiff University, School of Earth and Ocean Sciences. All data have been received by BODC as raw files from the RRS James Cook. Underway navigation, meteorology and sea surface hydrography from JC132 and JC102 have been processed using BODC in-house procedures and are available online. JC109 underway as well as sound velocity data for all cruises will be processed and made available online in the near future. Remaining data have been archived and are available as raw files on request.

  • The dataset comprises 87 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from all across the North Sea area during July and August 2005.
