  • This dataset contains a variety of hydrographic measurements including temperature, salinity, sound velocity, current speed/ direction and seismic data. Hydrographic profilers provided measurements of temperature, salinity, sound velocity and density. Four mooring stations were also installed as part of this project, with three minilogger chains providing temperature data and four moored ADCPs measuring current veloicty. The project ran from February 2006 to September 2009, however all of the data were collected between 17 April 2007 and 14 May 2007 during two cruises which took place in the Gulf of Cadiz. The research was conducted using two research vessels, the RRS Discovery (cruise D318) and the RV Poseidon (cruise PO350). The RRS Discovery cruise D318 was split into two legs, D318a, which took place between 17 April 2007 and 23 April 2007 and D318b, which took place between 29 April 2007 and 14 May 2007. For the second leg of cruise D318, the RRS Discovery was joined by the RV Poseidon. Hydrographic measurements were taken using a variety of instruments, including expendable bathythermographs (XBT), expendable CTDs (XCTD), conductivity-temperature depth (CTD) profilers, acoustic doppler current profilers (ADCP) and VEMCO minilogger chains. Airguns and streamers were used in the recording of the seismic data. The main objectives of the Geophysical Oceanography (GO) project were A) To evaluate and improve new research methods in the developing field of seismic oceanography by exploiting the opportunity of two-ship operations between RSS Discovery and RV Poseidon and B) To study the internal wave field and mixing processes in the Gulf of Cadiz and demonstrate quantitative links between seismic and oceanographic measurements. The cruise was coordinated by Durham Univerity and funded under an EU grant as part of the Framework 6 NEST programme. Eight scientific institutions were involved in the project. These were: the University of Durham, the Proudman Oceanographic Laboratory (POL), the Helmholtz Centre for Ocean Research Kiel (IFM-GEOMAR), the French Research Institute for Exploitation of the Sea (IFREMER), the Italian National Agency for New Technologies, the Energy and Sustainable Economic Development (ENEA), the Spanish National Research Council (CSIC), the University of Western Brittany and the University of Lisbon. Data from the programme are held at the British Oceanographic Data Centre.

  • This dataset consists of (1) Bulk properties of sea surface waves, including significant wave height, period and direction. Some additional wave properties relevant to their impact at the sea bed are also included: friction velocity, bottom orbital velocity, direction and period at the sea bed. (2) Depth-averaged eastward and northward current components and sea surface height above sea level. Additionally, eastward and northward current induced stresses at the sea bed. The modelled two datasets are prepared on the same regular grid. With a resolution of around 1/9th x 1/6th degree, i.e. ~ 12km. The continental shelf model extends from 48 to 63 degrees longitude north and from 12 degrees longitude west to 13 degrees longitude east. The dataset was generated by the Proudman Oceanographic Laboratory Coastal Ocean Modelling System (POLCOMS) and the spectral wave model (WAM). The data are available in single monthly files, for a 10 year period from January 1999 to December 2008, the POLCOMS data are 30 minute averages, and the WAM data are hourly. The dataset was generated by the UK National Oceanography Centre, Liverpool. The dataset consists of 240 data files in Climate and Forecast (CF) compliant NetCDF format, 120 from POLCOMS and 120 from WAM. This work is funded by the Aggregate Levy Sustainability Fund (ALSF) under contract MEPF 09-P114 and NERC National Capability funding. More information about the modelled data set and its applications can be found in Bricheno et al. (2015), and Aldridge et al. (2014).

  • Nitrogen Fixation was determined from samples collected during CTD profiles at the surface and chlorophyll maximum once per day from the North Atlantic at approximately 24.5 degrees North on cruise D346 between 5th January and 19th February 2010. The samples were incubated at sea-surface temperature for 24 hours, filtered onto ashed-GF/F's and dried in oven at 50 degrees for further 24 hours. The data are being used as part of a wider study in the role iron has in nitrogen fixation. David Honey collected these data as part of his PhD, supervised by Martha Gledhill and Eric Achterberg.

  • 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.
