Overall objectives in the EU GO project are to assess the promising potential of seismic imaging for physical oceanography, in view of its combination of fine resolution and coverage unmatched by conventional oceanographic measurements. D318 was to provide the means of assessment by obtaining a unique, comprehensive, oceanographic and seismic dataset at the same time and place. Specific objectives for R.R.S. Discovery cruise 318a were to deploy four ADCP moorings, three adjacent temperature-logger moorings and STABLE, in an L-shape array in 750-1000m depth east of Portimao Canyon, carrying out adjacent CTD stations, deploy two OBH moorings, carry out seismic sections using the Ifremer high-frequency air-guns and streamer, accompanied by regular XBT and less frequent XCTD casts. In addition underway data was logged including ship-borne ADCP, surface temperature and salinity, meteorology, gravity and magnetics (to test new NERC magnetometers).

Oceanographic research cruise collecting chemical, biological and physical continuos and discrete data measurements of the water colum as part of the "TInto Odiel river ocean study" (toros) program. A major goal of this study is to understand th eimputs of th Tinto an Odiel Rivers, two acidic and trance metal-rich fresh water source inputs, to the continental shelf and Gulf of Cadiz, Spain. The TOROS program is funded in the framework of the European Union Environment and Climate and the European Land Ocean Interacion Studies (ELOISE)program

The overall objective of the cruise was to identify the pathways of sediment transfer from the conjugate margins of Algeria and of the Balearic Promontory to the Algerian Basin from the Early Pliocene flooding of the Mediterranean to the Present.The cruise is the result of a co-operation between the University of Barcelona and OGS within HERMES (Hotspot Ecosystems Research on the Margins of European Seas) Integrated Project.The proposed research complies also with the objectives of the Collaborative Research Programme ESF-EUROCORES on EUROMARGINS 'WEST-MED' and 'SPACOMA'. The survey has been planned in order to fill the bathymetry among existing data sets:- Spanish EEZ project (Instituto Espa?ol de Oceanografia and Instituto Hidrografico de la Marina);- The BALCOM Project (Instituto Espa?ol de Oceanografia);- And the MARADJA Project (Universite de Bretagne Occidentale and IFREMER).In addition the survey area covers the track of multichannel seismic profile MS-46 acquired by OGS in 1972.The cruise went very smoothly, helped by excellent weather conditions and proper functioning of the instrumentation. Departure from Palma on Sep 20 15:50. Begin of multibeam and chirp sonar survey the same day at 20:00. Start of multichannel seismic survey on Sep 27 at 17:45. End of operations on Sep 29 at 24:00. Arrival in Cartagena on Sep 30 at 12:00.
