Main Question or Discussion Point

Hi,
How far does sound travel underwater, and more importantly does it travel further in water than in air? If so why? I know that sound travels faster through water than air for obvious reasons (density), and I intuitively assume further, but I cannot explain why. Any help is appreciated.
Thanks

This is not explanatory, but whales, using very low frequency sound, can communicate across oceans.

To expand a little on what Kenneth Mann said, whales can emit sounds so loud they cavitate water. I have heard it suggested that before the days of motorized ships it would have been possible for a whale at the north pole to have been heard by one at the sourth pole.
