What happens to photons of light that only penetrate the open ocean so deep? Why don't they hit the seafloor?

They are absorbed by the water molecules, and as a result the water heats up. If you want to look at it on a photon level, each has a probability of getting absorbed as it propagates, and the probability that it does not get absorbed approaches zero as it propagates deeper and deeper. Multiply this by a bajillion photons and you have a very very small number reaching the bottom.
