Hi everyone,
out of curiosity- are you aware of a reliable housing or something similar that can be mounted for example on a rosette during deep casts?
I'm looking into the available technology but of course in most cases only ROVs are used for dives that reach 1000m. It is not meant for research- we're simply looking for a "cheap" way to obtain videos during CTD casts.
The best scenario would be if we can build something ourselves to mount for example a gopro with a light source in a housing onto the frame.
Any ideas are more than welcome !
Thank you in advance,
Naomi
Hi Naomi!
I don't know of any commercially available housing for such an application. However, the first idea that comes to my mind is using a short piece of galvanized tube (e.g. 3 inches wide), with threads on both ends, fitted with a cap on one end, and a drilled cap with an o-ring and a transparent acrylic sheet (~15-20mm) on the other (see image). Your camera could be then put inside, facing the acrylic window on one end.
Of course you would need some machine shop experience to do this, but I would argue that it can be constructed quite easily and also cheaply (probably less than 100 euros), while the tube would be strong enough for the pressures you are describing (~ 1000 dbar).

Hope this will at least be a starting point.
Good luck with the project!
