| Abstract | The working area of the METEOR cruise M79, Leg 2 was located in the region of the Azores in the eastern North-Atlantic. During the cruise, one seismic wide angle refraction line was acquired in the region of São Miguel. A second line crosses an aseismic section of the Gloria Fault in the further east. Here, the acquisition has been designed to study the crustal structure of the African-Eurasian collision zone. Gravity and magnetic data were simultaneously collected during profiling; this data will be used for combined seismic and potential field modeling. Bathymetric measurements have been carried out mainly with the hull mounted EM120 swath sounder. A swath of 256 preformed beams is emitted periodically with signal frequencies of 12 kHz. In areas shallower than approx. 300 m bathymetric measurements were carried out by the EM710 swath sounder in order to get a higher resolution and to prevent system failures. The EM710 is operating with a signal frequency of 70-100 kHz. |
