They form or were all formed in the atlantic and pacific ocean which is salt water, but salt helps melt ice so is it actually saltless water? or is it just so cold that it freezes anyway?

Icebergs are chunks of ice cap or glaciers which have "calved." Icebergs contain bits of dirt and rock from the land and ocean wave splash puts a thin rind of salt on the exterior, as it floats along. However, icebergs are frozen rain and snow from the land - not sea water.
On the other hand, _Sea Ice_ is sea water that has frozen in the sea, usually at the poles. NASA explains "Although sea ice is made from salty sea water, the salt molecules are rejected back into the liquid as ice forms. There isn't much room for salt molecules to be trapped in the close-knit structure of sea ice." http://southport.jpl.nasa.gov/polar/iceinfo.html

people get confused about the difference between icebergs and sea ice.
Sea ice is generally not much more than feet thick, and comes and goes with the seasons. They are formed from salt water, but the salt is frozen out.
Icebergs are bits broken of glaciers. Glaciers are frozen rivers that flow down to the sea and break off. They are fresh water.

No, there is no salt in ice-burgs. As previously answered, the Ice-bergs are formed by glaciers meeting the sea. Interesting fact, the largest desert in the world is Antarctica. Virtually no participation . Most of the snow there fell tens of thousands of years ago . Pretty neat, ey ?

They are fresh water. The ice forms on top of the water and the salt doesn't get included in the ice.

For the most part icebergs are fresh water. The reason is that when ice
freezes slowly enough to not trap salt water inclusions, the complex crystal
structure of ice
does not provide any space for the salt to become incorporated into the
crystal structure.

salt doesn't melt ice, salt lowers the freezing temperature of water.
which means the water with salt in it has to be colder to get to the freezing point. Interestingly experiments with super cooled magnets show them spinning a levitating...interesting to think of when the magnetic north and south poles are both frozen.....
sorry i sort of got off the topic there...
Yes you are right " it is just so cold it freezes"

They have small traces of salt and other minerals. Icebergs even contain air entrapped from decades and even centuries ago.

yes they form from ocean water... which is salt water

No. Icebergs come from glaciers, which arise from precipitation of fresh water.

no they are the biggest resource of fresh water in the world. even rain doesn't amount up to ice burgs.
