Out There #2: The Crack

20 October 2015 - 12:44 AM

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 :)



Mezzo Canale Shoal [Tuscany - Italy]

I'm a bit embarassed to post a low quality video like this but the dive was amazing with a huge biodiversity of deep bentonic species.


I'm servicing my housing so Nauticam lent me a NA-A7 housing with a Sony A7 and a 10-80mm lens.

I used the camera without having the time to study all settings and for the Murphy's Law I had the wrong format: a 1440x1080 mov at 12Mbs :(

Moreover I had the camera set to FF while the lens is APSC. I thought that zooming in a little bit would do the trick but I was wrong.


Anyway, Next video with this setup will be better, I hope ;)




Mezzo Canale Shoal ( http://goo.gl/maps/mGpNj) allows you to experience in a single dive most of the excitements which attract us to the underwater world: the encounter with rare and captivating sea creatures and the sense for both adventure and exploration of a spot in the middle of nowhere. Feelings enhanched by that sense of peacefulness and inner silence, typical of underwater diving.
The huge biodiversity of bentonic species of this shoal reminds us of how the Mediterranean sea would be and what it is we've got to lose with our social behaviour.

NA-A7 buoyancy

I have a sony A7 with a 10-18mm in a NA-A7 housing and some.

Do you know if it has a negative or positive buoyancy?

Thank you in advance
