Additional Information
There was an attempt from a group of divers to create an artifiicial reef before several years so they had collected and sunk purposely some metal objects -mainly domestic appliances- in order to foster marine life on the spot. The site seemed ideal for this initiative as the seafloor composition on the spot was partly sand but this was due to the damage and shrinkage that the seagrass ecosystem (Posidonia field) had suffered over the last decades, from the uncontrollable anchorage of leisure boats. Apparently even after several years this accumulation of sunken metallic objects didn't seem to act as an artificial reef and there was a potential danger of pollution as most of the household appliances and electrical devices (i.e air-con units, fridge unit) weren't disarmed from their tanks containing the cooling liquid (freon), or their electrical wiring containing mixed metals and plastic isolation.

Comments and Feedback
Most of the organic material and marine organisms that were found on the metallic parts and appliances -mainly sea urchins, fire worms- were carefully removed before the recovery of the sunken objects.
