High-resolution marine magnetic surveys for searching underwater cultural resources
Main Article Content
Abstract
Recently two marine magnetic surveys, combined with the use of a multi-beam sonar (Kongsberg Marittime EM
300 multibeam: 30 KHz frequency echosounder for hydrographic purposes; acoustic lobe composed of 128
beams able to cover a 150° sector) a side-scan sonar (Simrad MS 992 dual-frequency sidescan sonar with echo
sounder transducers 150 Hz and 330 KHz) and a Remote Operated Vehicle (ROV a mobile tools used in environments
which are too dangerous for humans), were executed in two sites respectively in the Ligurian Sea and
the Asinara Gulf. The aim of these investigations was to test modern instrumentations and set new working procedures
for searching underwater cultural resources. The collected and processed magnetic data yielded very satisfactory
results: we detected submerged and buried features of cultural interest at both sites, at depths of 40 m
and 400 m respectively.
