JB, water does cut out more light than air, water is 40 times more dense than air. Take a light reading 30 feet above sea level, one at sea level and one 30 feet below, for sure there will be a large difference between the other two and the one at 30 feet below.
Interesting thread, and TONS of information to absorb. Doug
