How long can melt the iceberg?

There are several versions of the death of "Titanic." But the most famous three of them: a collision with a large iceberg, the explosion of fire in the holds of coal; design errors during the construction. The most probable cause of the accident is the iceberg, though its none of the survivors saw and the collision is not felt. But it is possible to say that the surface of the water from the iceberg is a very small area (about 10% of the total weight). For this reason, punching the side of the ship can only be underwater (larger) part that is invisible, but serving in the deep as a battering RAM to 100 meters or more. Pouring into the holds water it could lead to an explosion of coal that was smoldering due to self-heating. However, there remains another contentious issue: could a breakaway glacier to fall into the latitude where he faced the Titanic? Anyway, long live the floating icebergs and what are they in scale? Photo: Depositphotos Greatest number of icebergs "makes" Antarctica. Second place in Greenland. Shapes and sizes of icebergs can be very different. Even in color they are very different. But they have one common property: they float under the influence of wind and sea currents. The latter can bring the ice mountain anywhere. Scientists have long follow the "travelling" of icebergs. And here not only of scientific interest, but for purely practical purposes, the safety of ships. Regular observations began in 1913. Then they expanded and are now conducted not only ships and aircraft but also by using satellites from space. All large icebergs (about 900) listed in the special register, and the data about their movement are changing every day. The problem is that there are many more unaccounted icebergs of medium and small size. For this reason, in the last century, in addition to "Titanic," icebergs collided and sank together with the crews of two large ships: the brig pyatimetrovy "Copenhagen", who died in 1928, and the ship "Hans Chetkof" — 30 years after this incident. Both ships belonged to Denmark. "Copenhagen" in the picture Pedra Christian Petersenite: ru.wikipedia.org Floating ice mountains, observed in many countries. Then, of course, as of melting ice, they were gone. On average, the process of extinction of the iceberg can last 10 years — provided that the currents bring it in pretty warm water and he sat there stranded. Here the work enters the sun which can do much more than warm water. But history knows cases when the icebergs are in very cold waters and live there for many decades. In particular, the icebergs of Greenland currents sometimes bring in the direction of the North pole. More precisely, in the direction of Russia. Sitting on the ground, such icebergs gradually gained the snow. He turned into ice. The center of gravity changed, and the iceberg did a "somersault" — was overturned, lifting themselves from the bottom of a huge amount of soil. From outside could seem that the sea has a new island. Remember the famous land of Sannikov. Photo: Depositphotos was in the Northern ocean and many more like real Islands. But after a century the climate warming they all disappeared and the theme of the "unknown" Islands in the Arctic ocean has been closed to research completely. In place of Islands found then only the shallow banks — the remnants of the sludge that settled to the bottom after the melting of icebergs. ...
