I just watched the movie Battleship the other night. Aside from some awesome braddah-braddah cameos and a sprinkling of pidgeon, it’s mainly explosions. But there is a scene where the Japanese captain uses a buoy grid off of Oahu to track an alien ship’s movement.
Now my suspension of disbelief is okay with weird-handed extraterrestrial invaders leap-frogging their way across the ocean, but immediate wave height data from a buoy and a grid that seems to contain a station every 20 miles? Yeah, right.
