Campaña: ANTARTICA 2012

Hydrograpich survey. Antartctic cruise CTM2009-06256-E CTM2009-08287-E

The scientific goal of the cruise is to improve our knowledge of the geodynamic evolution of the Gibraltar Arc System (GAS) from improving the existing dataset in particular margin segments of the westernmost Mediterranean. Particularly, the Miocene to Holocene tectonic evolution of the shallow crust, as determined by its deformation pattern, tectonic partitioning and kinematics, neotectonics and active tectonics. The survey was conducted in three different crustal scenarios: 1) a relatively thinned continental crust at the Palomares and Cartagena margins; 2) an anomalous or oceanic crust at the ocean-continent boundary located at the foot of theses margins, and to the east of the Alboran Basin; and 3) a highly fractured and sismogenic continental crust at the Alboran southern margin (Morocco Margin). The survey consisted in acquiring multichannel seismic profiles and concurrent, multibeam bathymetry, and magnetometer and gravimeter records.
