The word "iceberg" in translation from German means - "ice mountain". Icebergs are formed when a large block of ice breaks away from ice shelves in the Arctic and Antarctica. Since the density of ice is 920 kg / m³, and the density of seawater is about 1025 kg / m³, about 90% of the iceberg's volume is under water.
Interestingly, these ice giants travel enormous distances. For example, icebergs from the Arctic swim almost to Bermuda, located at a distance of 4, 000 km from the place of their formation. But Antarctic icebergs can be seen in the area of the Brazilian city of Rio de Janeiro. And this is more than 5, 000 km from the coast of Antarctica!
Some icebergs are huge. For example, in 2000, a giant of more than 10, 000 square kilometers broke away from the Ross Glacier in Antarctica.
Huge blocks of ice floating in the ocean pose a hazard to shipping. Everyone knows the tragic fate of the British passenger liner Titanic, which collided with a huge iceberg on April 14, 1912. This disaster killed about 1, 500 people.
Soon after this tragedy, the International Ice Patrol was created, which monitors the movement of icebergs and warns ships of possible danger. This service is funded by 17 countries. Interestingly, since the beginning of the work of the ice patrol in the North Atlantic, more than one person has not died from a collision with icebergs.
In the coastal waters of Antarctica, about 100, 000 icebergs are constantly floating. In terms of fresh water content, they surpass all rivers and lakes combined. Projects are being developed to use this water for irrigation in drylands. For this, it is planned to move icebergs over long distances using special tugs.
There are other original ways to use iceberg water. One Canadian company produces drinking water from melted pieces of icebergs that are fished off the coast of Newfoundland.
Lovers of spirits can also appreciate the taste of ice water. In the same Canada, vodka "Iceberg" is produced, which includes water extracted from icebergs. Producers are confident that this is the purest vodka in the world, because the average age of ice is 12, 000 years. An interesting advertising slogan for this product is “the best vodka in the world that you have tasted over the past 12, 000 years”.
