more dense
The ocean is most dense towards the bottom of the sea. As the water in the ocean gets colder it gets more dense.
Thermohaline circulation is the process of cold water at the poles creeping along the ocean floor. It meets with north and south polar water creates a dawdling subsurface circulation.
Deep ocean currents are created by differences in water density. Cold or salty water is more dense and sinks, whereas warm or less salty water is less dense and rises. In polar regions, much of the ocean water is tied up in ice sheets. The salt remains in the liquid water, so the water in these areas is very salty as well as very cold. This water is consequently very dense and sinks. It is replaced by water from lower latitudes. The deep, dense water then moves slowly across the ocean floor and eventually rises in warmer latitudes. These currents are connected, and are sometimes called the ocean "conveyor belt." One circuit can take 1000 years to complete0_O
cold ocean water is more dense than warm water
This section of the ocean from floor to surface is called the water column.
If water is evaporated salt remain in the ocean.
The water from a melted glacier is less dense than the water of the seas.

deep ocean currents form by the differences in the density of ocean water
Heavy rainfall makes water less dense because an increase in salinity leads to an increase in density. Rain does not contain any salt. Therefore heavy rainfall makes ocean water less dense. =)
