Specialists Oceanographic school at the University of Washington in Seattle (School of Oceanography at the University of Washington in Seattle , USA, have discovered the source of the abiotic (non-organic) synthesis of hydrocarbons in the bottom of the Atlantic ocean, reported ScienceDaily. Biotic (organic) hydrocarbons, including the components of oil and gas reservoirs, are formed from the remains of prehistoric plants and animals. This time the analysis excluded the variant of organic origin. The report on the results of work of scientists published in the journal Science. According to experts, in open their source of hydrocarbons are born as a result of simple chemical interaction of water with rocks. The source is in the middle between America and Africa, the North Atlantic ridge at a depth of 800 m in hydrothermal field, which is called the “Lost city”. It was opened in 2000 and received its name in Association with the name of the mountain massif “Atlantida” (Atlantis), on which it is located. Continue reading
Christopher Swann – professional diver, photographer and writer from Britain. Having started in the distant 1965, Christopher and to this day never ceases to surprise and delight fans of his work from around the world. Today we present to your attention a series of incredible photos taken at the coast of the Azores in the Atlantic ocean.
The photographer managed to capture mnogumina frenzied battle for life – violent hunting of dolphins, sharks and Mediterranean petrels on a huge shoal of the blue Jack mackerel. In the photo we see thousands of fish gather in huge shimmering ball, about 9 meters in diameter, in a vain attempt to maintain their fragile life. Hungry underwater predators ruthlessly hit a flock of helpless fish. Trying to escape, mackerel rises up to the surface of the water. However, here they were waiting for another danger – Mediterranean petrels, wishing to receive the part of production. Continue reading
In subtropical latitudes of the Atlantic ocean in the warm season of the prevailing air mass is the Maritime tropical air in winter air from temperate latitudes.
In the warm season in the Western parts of the ocean subtropical latitudes prevailing winds blowing from low latitudes to high, and in the East of the high latitudes in low. Therefore, in the Western parts of the ocean in a warm season are observed at higher temperatures than in the East. It should be noted that in the warm season in the Eastern parts of the ocean subtropical latitudes water temperature is below the temperature of air, which prevents the development of convection. Therefore, in the Eastern parts of the ocean subtropical zone of the precipitation falls in the summer few. So, on the island of Madeira, the amount of precipitation for the period June-August is just 15 mm In the Western parts of the ocean, the air comes in the subtropical zone of the low latitudes. It significantly dampened. In these parts of the ocean water has a higher temperature than the air that leads to the development of convection and the formation of deposits of local importance. Because of this precipitation during the warm season in the Western parts of the ocean subtropical zone falls much. On the Bermuda Islands, located in the Western part of the subtropical zone of the Atlantic ocean, precipitation for the period June-August is about 300 mm Continue reading
