... it gets dark pretty quick down there. Even at 100ft/30m you've lost a lot of the color spectrum. So they'll take a lot of lights with them. Okay, fine. Don't expect any sweeping vistas -- the background's going to be black.
What are they going to film for Avatar 2 that they can't film a few thousand feet shallower? Neat rock outcroppings? The only thing I can think of are bizarre critters, which will be done in CGI anyway.
I'm all for exploring the depths, but whoever said the Avatar 2 angle is a tax write-off was dead on.
I've collaborated on research using Twitter traffic as a predictor so I applaud their efforts, but a 79% correlation with telephone responses is not as high as it sounds. For example, the minimum acceptable correlation for interrater reliability is typically 80%.
Put simply, the Twitter data can only account for about two thirds of the variation in phone responses. That's useful but there's still a lot of unexplained variance -- we have a long way to go.
With your bare hands?!?
