Scientists have discovered a giant “dead zone” in the Atlantic Ocean – ID Altapress

So-called “dead zone” of natural origin discovered in the Atlantic Ocean, scientists.

If you are usually “dead zones” – areas with low levels of oxygen in the water, formed under the influence of human activities, a new kind of zone has a different origin and is formed naturally without outside interference.

The fact is that, as a rule, in the discharge of industrial waste water is the cause of this place “dead zone” because the microscopic algae die and delee It begins the process of refining their bacteria. It requires large amounts of oxygen, which is consumed by bacteria, thus greatly impoverish the water.

However, oceanographers have recently stumbled upon a “dead zone”, the formation of which is not related to human activities.

It turns out , in the Atlantic Ocean off the coast of Africa, there are peculiar funnel in which the rotating water masses do not have time to exchange oxygen with stagnant water, which leads to oxygen-depleted top of this education.

According to experts, the diameter of such entities It reaches more than 100 kilometers and a depth of several hundred meters. It was assumed that the oxygen content of 100 m the surface water may be about 1 ml per liter of water. However, as a result of the measurements revealed that the figure actually is 0.3 ml per liter.

Scientists believe that the movement of natural rotating funnels very dangerous for all life in the ocean, because getting into the funnel, living organisms can die from lack of oxygen – wrote informing.
