ABSTRACT

The side scan sonar is the main tool for deep marine archaeology research but is also
equaled significant in mapping of underwater geophysical features. Ancient and modern
shipwrecks can be located with the correct translation of sonar records in conjunction
with visual inspection. During a short but difficult side scan sonar survey (for
documentary film purposes) in searching for the shipwreck HERAKLION (without
results), at the sea area north of Antimilos island (South Aegean Sea, Greece), we
recorded two interesting targets as well as geological features like mass flows, small
scarps and pockmarks. The surface sediments are instable due to varieties of slopes and
the pockmarks as seabed depressions indicating, with or without hydrothermal venting,
volcanic activity and/or seismic activity.
