Purpose | |
Abstract | During the second leg of cruise M12 seamounts were analyzed using geophysical methods (refraction seismic) to investigate the structures of these seamounts and the area around them. Additionally other geophysical methods like magnetic measurements were done. The collected data was used to investigate if these seamount are fixed hotspots or if they intruded in weak zones in the oceanic plate (intraplate volcanism). During the entire cruise Hydrosweep Data were collected- 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. |
