Icebergs that are hundreds of years ago broke away from the mainland and still swim in the ocean — some of the most beautiful creations of nature.
Every year hundreds of thousands of icebergs break away from glaciers and sliding into the sea near the North and South poles.
The researcher glaciers Robert Gilmore, which happens every year in Antarctica in expeditions to Polar Latitudes of the organization, said: “They melt incredibly slow. And slow moving, with a maximum of two nodes depending on the current. Icebergs vary greatly in appearance. Darker streaks on some of them can occur when freezing water penetrates into the cavity and refreezes. Blue icebergs are older and smaller, so they don’t refract the light and it turns a kind of optical illusion”.
On the surface of the water you can see only 10% of the total volume of the iceberg, and the rest is hidden under water.
Some of the icebergs, formed from the clumps of snow, swim more than 30 thousand years.
