Ziel der Reise / Objectives of Cruise:

Recovery of 30 ocean bottom seismological stations (OBS) in the Alboran Sea that have been deployed in August of 2009 during the cruise P393 of RV POSEIDON. Deployment of 24 OBS in the Gulf of Cadiz. OBS record in both survey areas the local, regional and teleseismic earthquakes for 5-6 month. The major aim of the research is understanding seismotectonics and hence delinating featres that may cause seismic hazards in the Alboran Sea and the Gulf of Cadiz. In addition, recorded travel times from earthquakes will be used to derive a crustal and upper mantle velocity model of the area. POSEIDON left Malaga on January 15, 2010 at 8:20 a.m. local time and stated recovery in the Alboran Sea after 6 h of transit. All stations were recovered in the afternoon of January 18, 2010. During the night POSEIDON sailed westward, reaching the fist deployment position in the Gulf of Cadiz at 8:15 a.m. local time. On January 22, 2010 the last station was deployed at 11:00 a.m. local time. In total 30 ocean bottom seismometers were recoverd from the Alboran Sea and 24 seismometers redeployed in the Gulf of Cadiz.
