deep zone
The densest ocean water will be found towards the poles, were sea water is freezing. The salt of the sea water does not easily fit into the ice crystal mass of the ice floes, and will blow off into the ocean. Thus increasing its density. Called the Thermo-haline current, and of great importance in creating oceanic circulation.
A basic answer is that the densest ocean water is the saltiest - a ship floats higher in salt water (sea) than in fresh water (lake). Also cold water tends to sink towards the ocean floor, or may form a layer mid way.
the most densest region of the ocean is inside the red rectal system galaxy of the 3rd quadrant. the last time me and the homeboys went there yall homies were all up in my grizzle. word.
salt water is densest
From its Wikipedia page: "Being the densest water mass of the World Ocean, AABW is found to occupy the depth range below 4000 m of all ocean basins that have a connection to the Southern Ocean at that level." The Southern Ocean freezes at about a depth of eight to 12 feet during the winter months, which is not deep enough to freeze the bottom water.

Ocean water is generally slightly basic.
Polar regions produce the densest waters because of the cooling and freezing there.
Because water is densest at 4C, so it will sink to the bottom of the ocean.
There is a deep saline lake under the ocean water in the Gulf of Mexico. I believe that would qualify. See what the Geekologists have to say in the link below. Of course, the "no kidding, duh" answer is "At the bottom."
It is the Atlantic Ocean. The Pacific is closed off by Siberia and Alaska in the Straight of Bering, and the Indian Ocean is almost in the Souther Hemisphere. The biggest flow of Artic water goes into the Atlantic as the densest and coldest layer of water in the Northern Hemisphere called North Atlantic Deep Water.
