Type of Debris Tires
Comments Inside tires and large bottles; had Octopus Mollusc

The largest and heaviest debris that had to be removed with cranes are the tires they install as a defense of the fiscal spring.

Pistons of a large engine.

Tires stuffed on the seabed


Considering that there was a large amount of garbage, a previous diagnosis was made with a side-scan sonar (enterprise Viejo Lobo de Mar). The result of underwater sonar prospecting was vital in planning seabed clean-up

Prior to the seabed cleaning activity, 3 talks and a diving briefing were given by the Master Scuba Trainer Instructor PADI # 395352
