It depends on the concentration of salt, but at the average salinity of the open ocean (about 3.5%) the water freezes at about 28 degrees F

The first marc above has it wrong..... Water freezes at about 0 degrees CELSIUS (32 degrees F.)... that's without salt...
But like the person said about me, salt LOWERS the freezing point depending on the amount of salt (salinity) in the water...
It is a linear function, in that the more salt you add, the colder the water will have to be in order to freeze. Double the amount of salt, and the temperature needed to freeze it, lowered by a factor of two as well.
Average sea water, which has a salinity of 35, will freeze at -2 degrees CELSIUS...

Of course it can. Dissolved salt only drops the freezing point. But if the weather is colder than the freezing point, as is the case in most of the Artic, the sea will freeze (at least for now). That is why we have "ice breaker" ships that clears the sea lanes in winter.

Yes. Salt water freezes at right around 0 degrees farenheit. Depends on the concentration of salt in the water.

Yes, but at a lower temperature than normal watter depending on the amount of salt and other non volatile solutes (non gaseous) in it.

Of course, it just freezes at a slightly lower temperature. What do you think an iceberg is?

yes, concentration of salt also affects freezing

yes at around 0F. much colder than pure water.

it should-----the salt should not effect it
