In reality, however, in order to get the amount of detail required to locate relatively small
artifacts, their operative range was limited to no more than 70-75 m. Unfortunately the
remotely operated vehicle (ROV) available on Hercules malfunctioned after only a few
dives. As a result, most of the acquired targets in the deep waters of Croton remain
uninvestigated.
Considering that the 47 km of coastline from the Neto River to Praialonga
represents a remarkably large area to investigate in less than a month, we created small
adjoining navigational grids. Each sector could be covered in eight or nine hours with
Juno and Hercules, weather permitting. The survey’s swaths were set using PDS 2000
navigation software. At the end of the campaign, approximately 50% of the designated
survey area had been covered. The area between the harbor of Croton and Capo Cimiti
from 5 m to 75 m deep was nearly entirely surveyed. The two research vessels could
cover only a small fraction of the sea from Capo Cimiti to Le Castella; the seafloor
between Le Castella and Praialonga remains totally unexplored (Fig. 22).
