Description:
The TOMO-ETNA experiment was performed in the framework of the
FP7 “MED-SUV” (MEDiterranean SUpersite Volcanoes) in order to gain
a detailed geological and structural model of the continental and oceanic
crust concerning Etna and Aeolian Islands volcanoes (Sicily, Italy), by
means of active and passive seismic exploration methodologies. Among all
data collected, some 1410 km of marine multi-channel seismic (MCS) reflection
profiles were acquired in the Ionian and Tyrrhenian Seas during
two of the three oceanographic cruises of the TOMO-ETNA experiment,
in July and November 2014, with the aim of shading light to deep, intermediate
and shallow stratigraphy and crustal structure of the two
above mentioned areas. The MCS sections, targeted to deep exploration,
were acquired during the oceanographic cruise on board of the R/V
“Sarmiento de Gamboa”, using an active seismic source of 16 air-guns,
for a total volume of 4340 cu. in., and a 3000 m long, 240-channels digital
streamer as receiving system. High-resolution seismic profiles were instead
collected through the R/V “Aegaeo”, using two smaller air-guns
(overall 270 cu. in. volume) and a 96 channels, 300 m long digital
streamer. This paper provides a detailed description of the acquisition
parameters and main processing steps adopted for the MCS data. Some
processed lines are shown and preliminarily interpreted, to highlight the
overall good quality and the high potential of the MCS sections collected
during the TOMO-ETNA experiment.
