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).

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 318b were to (i) recover four ADCP moorings, three adjacent temperature-logger moorings and STABLE, from 750-1000m depth east of Portimao Canyon (ii) perform deep water CTD casts (iii) carry out seismic sections using the NMF supplied Bolt airgun and streamer, accompanied by regular XBT and less frequent XCTD casts, iv) work with MV Poseidon to test novel seismic data acquistion strategies. 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

Estiamtion of the abundance of pelagic fish present in the North-east Atlantic waters in spring which is the spawning period for these fish species, but focussing in sardine and anchovy. Complementary to this main objective the survey design and strategies will allow the enviroment be characterised by recording differente variables (i. e. temperature, salinity, fluorescence, plankton, winds or air temperature) in vertical and horizontal profiles along the surveyed area with no noticeable extra-effort. As it was pointed out, these variables will help the acoustic estimations be improved whilst an extensive environment characterisation at the spawning time will be done.

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.
