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.
