| Abstract | The origin of the Ionian Sea lithosphere and the deep structure of its margins remain a little investigated part of the Mediterranean Sea. To shed light on the plate tectonic setting in this central part of southern Europe, R/V METEOR cruise M111 set out to acquire deep penetrating seismic data in the Ionian Sea. M111 formed the core of an amphibious investigation covering the Ionian Sea and island of Sicily. Prior to bathymetric mapping with the Simrad EM122 system a sound velocity profile was acquired using an expendable XSV probe down to 2000 metres water depth, beyond which the profile has been extrapolated. Bathymetric data were mainly acquired for the need of correctly locating the OBH/OBS positions as well as the airgun shotpoints and their resulting water wave. |
