Why tank or ocean freezes from the surface not from the bottom in winter?

In winter, when the atmospheric temperature starts falling well below 0 degree C, the water at the surface of a tank or ocean initially at temperature of 4 degree C beings to radiate heat to the atmosphere, so the temperature of water starts falling. When the temperature of water at the surface falls, water contracts, so its density increases and therefore it sinks to the bottom. This continues till the temperature of the entire water reaches to 4 degree C.
In short this happens due to anomalous expansion of water.

Why doesnt Antarctic bottom water freeze?
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.
What is the opposite of bottom?
The antonym is bottom.
How are the seas of the Antarctic different in the winter than in the summer?
