The word “iceberg” is of Scandinavian origin and literally translated into Russian as “ice mountain”. These are huge, free blocks of ice drifting in the sea or ocean usually break off ice shelves of the North Pole, or Antarctica. Icebergs fascinate with its cold, majestic beauty and awareness the hidden danger they carry for ships. Over by the water surface, as a rule, only about 10% of of the total volume of ice, most of the iceberg is deep down below. That is why ship captains are doing their best staying as far away as possible from these giants is very difficult for sure determine the shape and volume of the bottom ice mass to avoid collisions.
Icebergs are of great interest to both glaciologists and and for representatives of many other fields of science. Some scientists examine them to determine the prospects for global warming, others try to solve the problem of water supply in the poor with their help and arid countries (though so far to no avail). Whatever icebergs are one of the most unique and impressive phenomena of inanimate nature. We suggest you find out which the largest icebergs were known to people throughout stories.

Joseph Fletcher Iceberg
This huge ice island, separated from the ice shelf Ward Hunt, was first discovered in the 40s of the XX century by American a pilot named Joseph Fletcher, in whose honor and subsequently an iceberg was named. The array is 50 meters thick and has an area of 90 square kilometers has long served as a location drifting scientific bases conducting polar research. Closer to The 1980s, research activities on the island were curtailed, and the ice island was carried away by the current to the North Atlantic Ocean, where gradually melted.
Iceberg in the Northern Hemisphere
An ice mass of about 200 meters thick discovered in 2010 year near Greenland was a unique phenomenon, since most often such large blocks are found only near Antarctica. Greenland Glacier Breakaway Area Peterman’s fragment was 260 square kilometers, which, for example, four times the size of a New York island Manhattan Slowly moving south, he is quite could be a real threat to the ships of the North Atlantic. TO fortunately, he changed the route on time and was melted by the warm current Gulf Stream.
This iceberg is located in the western part of the Ross Sea, it drifting off the coast of Antarctica since 2002. Climatic features of the area in which he found himself contribute extremely slow melting. The area of the giant block of ice reaches 5.5 thousand square kilometers, which is several times larger than the size Of London. Despite the inaccessibility of the location of the iceberg, surrounded by other, smaller pieces of ice, to researchers managed to install measuring and navigation equipment. It is noteworthy that in addition to the official name C19A, he also received the name Melting Bob.
Iceberg, code-named A-38, separated in 1998 from Antharctic Filchner-Ronne Glacier. He had 144 kilometers in length and 48 wide, and the area was approximately 6900 square kilometers. After a long drift across the North Atlantic, the icy the block split in half, which was recorded by the MODIS satellite in mid 2000s. Its eastern part moved to northwest, where it apparently melted, while another stretch drifted along the shores of South Georgia.
The largest iceberg in the history of our planet has been discovered and investigated in the year 2000. This massive ice island with an area of 11 thousand kilometers, which exceeds the size of Jamaica, breaking away from Antarctica, caused a catastrophic decline in population Adélie penguins because they interfered with prey penguins on time get to the cubs. He was also a serious obstacle. to supply resources to several scientific polar stations. By According to researchers, the weight of this giant was three trillion tons, and the water in it would be enough to feed the Nile River in for eight years.
In 2005, the B15 lost the title of greatest, splitting into several fragments after a collision with an ice tongue Drigalsky.
The infamous iceberg, the collision with which led to the death of the largest at that time liner “Titanic”, separated from the Greenland glacier. At the time of the collision, its height It reached 105 meters, and it weighed about 420 thousand tons. One of reasons why the ship noticed too late approach ice giant, was his color. He belonged to flipped icebergs that are much darker due to inclusions of veins of more dense ice and inclusions of various rocks captured during drift. Such a “black” iceberg It has long been considered sailors many times more dangerous than ordinary white blocks. After a terrible disaster that claimed the lives of 1,495 people, he continued drift until he ran aground near the land of Franz Joseph.
The tragedy caused by the clash served as a powerful impetus to the creation of improved route forecasting systems drifting ice that made seafaring in the north and south latitudes are more secure.
Iceberg “Santa Maria”
A huge ice mass of 31,000 square kilometers It was opened in 1956 in the northern expanses of the Atlantic Ocean. Its length and width were 97 and 55 kilometers, respectively. “Santa Maria” underwent a surface study by specialists with USS icebreaker USS Glacier but more thoroughly to study it was not possible, since he soon melted away.
Iceberg at the Falkland Islands
The highest iceberg on the planet was discovered in 1904 in South Atlantic, near the Falkland Islands. Unique fragment drifting ice struck scientists, but unfortunately, imperfection research methods and technical equipment of the early XX century led to the fact that he was not thoroughly investigated. Height of this nameless iceberg was 450 meters, which exceeds Empire State Building height indicator of one of the most recognizable skyscrapers of the world.
