A deep dive in a strange deep place to test a prototipe of a couple of 12K lumen video lights.
Video nothing special, just a proof of concept for an upcoming project.
Out there, a few hundreds of meters apart from mooring buoys, nearby walls, reefs and wrecks there is a unknown world waiting to be (re) discovered. (https://goo.gl/P4yc1E)
Is the case of this huge underwater crack in Giannutri island, discovered by chance during a scooter ride on the lunar-like seabed. Simone Nicolini has told me so much about this place that we jokingly nickname it "Nicolini's Abyss". Later I discovered that "The Crack" was well known to other seasoned tech divers but nobody was able to give me a convincing description: depth, lack of reference points, low visibility played an important role giving this place an aura of mystery.
Hence the idea with Simone to film and document The Crack. Unfortunately we dove it just once in a low viz.
After seeing the clips my son is absolutely convinced that The Crack is no less than Godzilla's lair but geologists have a different opinion...
The Crack is located in this position: https://goo.gl/maps/ij2vbcjFfLv
Typically, moving out to sea, the island seabed slopes away up to 30/35 meters when a cliff side drops vertically to 50/60 meters. The seabed slopes away again to 70/90 meters where rock masses form small cliffs. Further on it gently slopes off to 100 meters and beyond.
The Crack has a rippling profile which follow the shape of a rock mass at about 95 meters and beyond. Its orientation is north-south, approximately parallel to the island west coast. In some points the crevice is just few centimeters wide while in a couple of points it is over one meter wide allowing a diver to carefully explore it inside. It looks like a tight cave follows the crack profile on the bottom.
We didn't find any dragon-tooth but my son didn't change his opinion
