Icebergs are made up of freshwater ice, which has a lower freezing point than seawater. The salt in the seawater reduces its freezing point, making it harder for the icebergs to melt. In addition, the dense, cold freshwater from the iceberg forms a protective layer around it, insulating it from the warmer seawater.
cold ocean water is more dense than warm water
Cold salty water will be the most dense.

Oh, dude, ice melts in cold freshwater because the freezing point of freshwater is 0 degrees Celsius, so when it's in contact with ice, it warms up and melts the ice. In cold saltwater, the freezing point is lower because of the salt, so the ice would actually melt slower. But hey, no need to lose sleep over it, ice is gonna do its thing regardless!

Seawater becomes more dense when the temperature decreases or when salinity increases. Cold water is denser than warm water, and water with higher salt content is denser than water with lower salt content.
As water gets colder it eventually becomes ice. So judging by that, as water gets colder the water gets denser to the point of being a solid. Cold water is more dence than warm water. Ice is less dense than water (which is why it floats) so... but I think the above is still correct.
Seawater's density varies by temperature and salinity. I.e., cold water is more dense than warm water, and water with a higher salinity (more dissolved salt) is less dense than water with a lower salinity.
As seawalter gets colder it becomes more dense, so cold sea water is more dense than warmer water.
Cold and dense
Mixing zone
the warm air is pushed down because its lees dense than the cold air if cold air is more dense.
Cold water is more dense.
cold ocean water is more dense than warm water
When dense,cold air meets less dense,warmer air, the warm air is pushed up
