Abstract | The main purpose of 49 leg 3 was to find locations for ODP later drilling proposals (Wefer et al.) aiming to study Quaternary sediments deposits as well as paleo-oceanic history of the area. Therefore during M49/3 the northern part of the oceanic margin in the Argentinean basin was investigated using seismic, bathymetric and other geological methods. During the entire cruise Hydrosweep and Parasound Data were collected. 9750 km of multi beam echosounding profiles were taken. The used Hydrosweep is a multibeam echosounder using a frequency of 15.5 kHz. The quality of profiles varies coherent to weather conditions and ship course. Though multibeam data was recorded, it was not the main focus of the cruise and no further information have been provided by the responsible party. |
