Abstract | The main objectives of SO146 was a multidisciplinary geophysical and geological investigation in the waters near Peru near 15 °S and 5°S. This study focused on a quantitative characterization of the structures and geodynamics of the Peruvian section of the Andean subduction zone and the associated gas hydrate systems in a region with differing tectonic development. The first leg focused upon the acquisition of 6 wide angle profiles shot with three airguns over 9 to 14 OH/S instruments. During SO146 the HSDS was used for continuous bathymetric recording, but it was not the main focus of the cruise and the responsible party provided no further acquisition information. |
