[PSUBS-MAILIST] Cave Dive

[Alan via Personal_Submersibles]

Thanks Keith,
I believe we were both at Simon Mitchell's talk on diving the Niagra, years ago.
He was the doctor I referred to that was part of this team.
Shanee's suggested was to use ROVs but I think that would be impossible as although the depth was 250M, the length was over 600 meters with lots of entanglements.
Perhaps an AUV with range finding & a good program could get a bit further.
You could get the AUV in to the point the divers went to using their dive 
profile & some collision avoidance.
BTW it was a 76 year old caver Peter Crossley, that asked me about my sub
going in their. Peter originally mapped the Abbey rd caves along with myriads
of others.

Cousteau did use the Denise sub on the Niagara when here. We had a Triton sub dive project set up for the past weeks to dive the Niagara but on hold due to the Covid-19 situation. Both divers were involved with the Thai cave rescue - Harry was the Doc who  sedated the boys and Craig assisted with diving them out - they have recently co-written a great book on the rescue well worth a read. You wouldn't get far with a Exo in the Pearce cave system.
