The ocean is stratified with denser layers below less dense layers.
a stratification is a term generally used for layering of sediments. Thus a "stratified" ocean is one in which a layer of sediments accumulate at the bottom of the ocean and over time, sediment infill from the continents fill up small local areas around the points where fresh water meets saline ocean water. These areas fill with so much sediments, eventually they become stratified with sediment layers and dry up.
