Answer to Question 1

When seawater freezes to form sea ice, salts do not become part of the ice; therefore, the salinity of the remaining seawater increases. An increase in salinity results in an increase in density.

Answer to Question 2

Deep-ocean circulation is driven by density differences in the water column, where denser water sinks to the bottom. The density differences are due to temperature and salinity; temperature is referenced by thermo and salinity by halinehence thermohaline circulation.
