Is Sea Ice Drinkable?

Can you drink melted sea ice? New ice is usually very salty because it contains concentrated droplets called brine that are trapped in pockets between the ice crystals, and so it would not make good drinking water.

Is sea ice pure water?

As the ocean water begins to freeze, small needle-like ice crystals called frazil form. These crystals are typically 3 to 4 millimeters (0.12 to 0.16 inches) in diameter. Because salt doesn't freeze, the crystals expel salt into the water, and frazil crystals consist of nearly pure fresh water.

Can you drink a melted iceberg?

Even though icebergs are floating in saltwater, the ice has no salt. It's compressed snow. If you melted an iceberg you would get drinkable fresh water after you killed any germs. Icebergs have never been used as a major source of drinking water because of the costs and risks associated with moving them.
