What is the mechanisim responsible for causing the very high density of Antarctic bottom water?

The mechanisms are temperature and circulation.
Sea ice concentrates salt. Seas in the Southern Ocean -- the Weddell and the Ross -- freeze over during the Antarctic winter -- and during that process produce polynyas which open surface water to the cold winds that blow off the continent. This freezes the water more quickly and . . . concentrates the minerals.
The water becomes laden with salt, and is colder, so it sinks, creating Antarctic bottom water.

What is an Antarctic density current?
Describe the Antarctic denisty current
How does a density current form in Antarctic?
it forms wind I think?
Name three density currents that form in the polar regions?
The Antarctic Bottom Water, North Atlantic Deep Water, and Antarctic Intermediate Water are three density currents that form in polar regions.
What is the density of antarctic bottom water?
1.028 grams per cubic centimeter
Which is a cause of density currents?
- evaporation - particles mixing with water - freezing
Is water density is responsible for water color?
No, it is not.
How does the volume and density of a substance change when it is heated?
The volume of a substance increases when heated, causing a decrease in density.
What is the transfer of heat causing differences in air density called?
Convection
What are spiral density waves responsible for?
They initiate new star formation. Therefore they are responsible for the formation of new stars.
What is responsible for the summer and winter stratification of lakes?
I believe it is because of density of water.
Density changes are responsible for which methods of thermal energy transfer?
Convection.
What is true of upwelling?
It is driven by temperature differences causing differences in density. It requires a gravity field.
