If you really think that's not a barrier, and it doesn't prohibit the two kinds of water from mixing. then you're disagreeing with science, not just with the verse that I quoted. Because if there's no barrier, as you say, then what is the halocline which is right between the fresh and salt water? Is the halocline just a "line in a diagram" meant to simpliify for the purpose of explanation? If so, I'd like to see a source or an article that supports that claim.
Furthermore, the halocline doesn't just prevent the fresh and salt waters from mixing. Even leaf litters, soda cans, and other light trashes are prevented from falling into the denser saltwater. And completely different set of life-forms live below and above the barrier. Even the level of oxygen in the water is different below and above it. Here's some science reading for you if you don't believe me:

Damn, you were totally right, Rhythm. There's no barrier at all.

Quote:Like oil on water, freshwater that seeped into the cave from the surface floats above a denser layer of saltwater from the ocean. These layers meet and mix in a lens of brackish water called the halocline. If left undisturbed, the halocline can be paper thin, yet still visible to the naked eye. Whereas saltwater and freshwater are clear, the halocline appears somewhat like a hazily defined liquid body rippling within the water. It can act like a barrier, preventing leaf litter from the surrounding forest — along with plastic bags, soda cans and other light trash — from sinking into the denser saltwater. Along with the debris, the upper freshwater layer contains more oxygen than the saltwater below, and it supports a completely different set of life-forms.
The halocline divides the freshwater and saltwater throughout the cave system of limestone passageways — so narrow in parts that a diver must detach from his oxygen tanks to fit through — and caverns sometimes large enough to drive a semi-truck through them.
Damn, you were totally right, Rhythm. There's no barrier at all.
