The Noah flood was celestial. It never happened on earth. The guys saying the Black Sea is the result of the Noah flood have a need to keep the funding coming in so they started this cockamamie stuff because gullible morons throw money at it just so long as it is something about Noah because they see how much funding people get trying to locate the ark. Notice too how the ark is never quite done away with. The door is always left open on this story. "We climbed Ararat and we could see the back end of the ark above the snow. It was amazing! And so HUGE!!!!!! But before we could close in, a big snowstorm hit and forced us back. But we would certainly like to return to the area as soon as the spring thaw hits." Somebody will offer to fund another expedition.
I'm assuming the guys in the Black Sea Flood theory know that the more astute among us know they're bullshitting about the flood in order to continue funding their true work. The problem is, they're now tied to this thing and it brings on the point at which your academic career becomes one of entertainment. You become a talking head if not a subject on "alternative science" programs rather than being a scientist.
