While this site relates to pilots, there are other websites and group discussion forums with folks that do this sort of underwater work full time. (thankfully, most are closed, and by invitation based on verifiable qualifications) This search has been a technical and logistical fiasco.
I know of many entities in the industry that have been trying to provide input into the search, but like most adventures of this type, it has been relegated to the blowhards.
Good luck.
