You people are priceless. This is very basic chemistry and fluid dynamics. The fact that all of you believe that fresh and salt water do not mix simply defies belief and shows how and why you believe in AGW.
They are able mix, but the rate of diffusion is very low and it takes mechanical action to achieve mixing. That is it takes additional energy added to get them to mix.

Waves http://hyperphysics.phy-astr.gsu.edu...s/watwav2.html Nice little explanation of how waves work. Water in waves just goes around in a circle unless they brake. Mixing? None. Currents, two bodies of water moving past each other, Mixing minimal. In the Bosporus as I've alluded to the waters flow in opposed directions with minimal mixing. In the Back Sea The less dense surface water and the more dense deeper water never overturn and there is not enough mixing to oxygenate the deeper water. The name Black Sea comes from the anaerobic conditions in the deeper parts of it. Tides, all the water moves together, not much mixing.
If you want to talk real mixing you have to look at upwellings driven by off shore winds. This action brings the deep water up and over turns that water column. Goolge El Niño for an explanation of what happens when the upwelling off of Chile brakes down.
In the real world in the real sea they don't mix that well.
More lying Global Warming BS. I regularly check a web site that shows that the govt. is altering old data, and lying through its teeth about how the temp goes up every year. Typical of our govt. today. Lies, lies, lies. There's no discernable change in the climate that has any negative effect on the life of most people. No seas rising, no permanent droughts, nothing.
Thank you for that thought-provoking response backed up by actual data...

This is liberal lunacy. Salt water and fresh water are completely able to mix. To suggest otherwise shows a complete ignorance of physics and chemistry.
There is a little issue called "equilibration" in which two fluids with different osmolarities, even when separated by a semi-permeable membrane, will equilibrate and have the same osmolarity over time. It is simple chemistry.
Further, via statistics and knowledge of entropy, two adjacent gases or fluids (provided they are miscible) will assume the same density of solute. It is statistically impossible that this NOT OCCUR.
Or there is very little I can do for you if you aren't going to look at what things actually do. Yes they do mix, and yes they don't mix, It is a matter of rate of mixing. The black sea is a good example. Fresh water flows in, it mixes with salty sea water and the mix flows out the Bosporus, the salt content is replace by saltier water flowing into the black sea and it does this at quite a clip. The surface water is less dense and heads into the Mediterranean. Water from the Mediterranean flows along the bottom and heads the other direction.
You realize that sugar is an organic compound and salt is an ionic, inorganic compound, right?
Do you realize that complex sugars are used for chemical separation density gradients to isolate compounds of different molecular weight/water content? Do you know why they do not use ionic salts for such density gradients?
Actually -- it does mix -- but as you have observed, not easily.
But you are looking at answer three not one.

And you do realize that when you say the addition of large amounts of fresh water to the North Atlantic will not slow or stop heat transfer you are wrong?
Now if that very dense brine can get a large distance (vertical) from the newly frozen sea water it will take time for it to get back there. It drops to the bottom. This drives a lot of the global sea water circulation.

And when the ice melts the water it is in is less salty than the rest of the ocean. The salt that was in the water that froze is a long way away from it when it melts.

What the hell is wrong with you? When are you going to accept that the climate is changing and because of that there will be serious repercussions? You claim to be a scientist, but nobody believes that because of your ridiculous posts.
I was a commercial fisherman and docked my boat in an inlet that had a river running into it. There was several feet of fresh water on the surface...This prevented sea life, like barnacles and mussels from growing on my boat....
It is far past time for you to admit that you are wrong about this issue, but from what I have seen, you are one of those people that cannot ever admit that you are wrong about anything...
When fresh water and saltwater meet in an estuary, they do not always mix very readily. Because fresh water flowing into the estuary is less salty and less dense than water from the ocean, it often floats on top of the heavier seawater.... NOAA's National Ocean Service Education: Estuaries
