World Oceans

Posts Tagged ‘oceans’

Almost until the beginning of the XX century, mankind had little idea of the oceans . Emphasis was placed on the continents and islands . They opened eyes travel to the era of great geographicaldiscoveries, and at a later time. Ocean during this time became known mostly only that he was almost three times more than the entire land. Under the surface of the water remained a great unknown world, whose life could only guess at the basis of isolated observations to construct a variety of assumptions. The hypotheses, especially fiction, were not lacking, however, was poorer than the fantasy of reality.

We used to call their planet Earth from outer space while it appears blue. This color is due to the fact that three quarters of the planet surface is covered with a continuous blanket of water – oceans and seas – and just over one quarter left to share the land. The surface of the ocean and land quality varies, but they are not isolated from each other: between them is a constant exchange of matter and energy. Huge role in this exchange belongs to the water cycle in nature .

Flow more strongly in the South Pacific trade winds from east to west. This is usually one of the biggest trends in the world. Stronger in the pursuit of its parts, which is north of Ecuador. Is "start " of the Gulf of Panama (in this case there is an analogy with the Atlantic Ocean and the Gulf of Guinea: there is also a similar equatorial flow). In the Galapagos flow – more than 20 miles per day, further west increases to 80 to 100 miles per day. This is more than the speed of some lowland rivers. Therefore not surprising that the islands of the sea has huge flow faster with multiple switches. When you 're standing in a bank may give the impression that the island is moveable, and not the sea, and that ' re in it sailing to South America. South-wind on the plane is a heating (+25- 28 C) and cold (+15- 20) of water. The latter are formed not only by the entrance of the cold Peruvian current, but also by the rise of deep water. Cold water is distinguished by its dark green dark blue warm waters. Jet of cold water corals inhibit the life of the Galapagos Islands, located in Ecuador. restless waters of this stream. What people say about them in the report of the expedition "Venus " (the beginning of the nineteenth century.): "The sea is divided into time slots interspersed with parallel bands of random surface and was worried chirped one. very thick blue, while in others it was smooth, dotted with jets of bright white. In these bands, the sea looked like a vast space of propagation, reminiscent of what passes under the bridge foundations in the river, the only difference that here the bubble extends to the vast space. "Rich and peculiar life in the waters of this trend. To describe it better also turn to the witnesses, and early twentieth century. Here 's how to describe B. Beebe, aboard the Arcturus plyvshy ": " 2 ° 36 'north latitude and 85 west * was discovered this wall of water formed by the meeting of the two warm currents from the west (note that this in open ocean, without any relation to the waves and winds aut -. Com) .. On a calm sea surface could be seen in zig-zag narrow band of foam (is tracking more than 100 miles – approx. Aut). Numerous birds – fulmars, boobies and frigate birds – flew over the area and is in constant appropriation of water extraction.  In the area of foam was an extraordinary accumulation of marine organisms, microorganisms have been here in such abundance, that in some places they gave the water the consistency of soup at once swam the trunks of trees, many of them were covered with mosaics of shells, there were numerous well as flying fish, sea snakes, up to three feet, and sharks.

How the oceans? The answer to this seemingly simple. About how he dared, until recently, we've talked. In the relief of the planet 's original deep depressions eventually filled with water. That 's it. But it was only the beginning of a long road to knowledge of the true history of the oceans and the actual processes that occur in them. Over the past decades due to widespread use of the latest research methods and measurement techniques, scientists have made many unexpected discoveries and surprising. The most paradoxical of them lies in the fact that the sea was younger than the ocean itself. In fact, the ocean geologic formations that are more than 140-160 million years – the age at geological time scale young.The paradox is that there are numerous and unequivocal evidence of ancient oceans, indicating that the oceans of the surface of our planet, there are at least 2.6 to 3 million years to a total age of the Earth 4.6 billion years. Where has "disappeared " at least four million years of Earth history? How to explain this paradox?
