| Abstract | Leg M70/1 focused on the geobiology of bathyal coral ecosystems in the central Mediterranean Sea.Deep-water corals with their large fossilisation potential migrated even into the eastern Mediterranean Sea during the Pleistocene as is evidenced by fossil coral assemblages on all seamounts and hard substrate slopes investigated. The acoustical geophysical devices employed during the surveys involved a SIMRAD EM120 and a SIMRAD EM710. Also the sub-bottom profiler PARASOUND was performed along some lines. The multibeam System SIMRAD EM710 operates at 70-100 kHz, it records depth measurements, multibeam side-scan and echo amplitudes providing bathymetric data up to 2000 m. The multibeam System SIMRAD EM120 operates at 12 kHz. It records depth measurements, multibeam side-scan and echo amplitudes providing bathymetric data within a swath width that can reach up to 5.5 times the water depth. |
