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 second leg was an interchange of high resolution seismic work with the combined recording on OBH/Ss, a streamer, heat flow measurements and observations of the ocean floor using the TV sled. 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. |
