Mystery of the discovery of the Atlantic Ocean Dead Zone
Mystery of the discovery of the Atlantic Ocean Dead Zone.
The world has some vast oceans, one of which is the Atlantic Ocean. This ocean has a very large area and has characteristics that distinguish it from other oceans
Scientists discover 'dead zones' in tropical waters of the North Atlantic. Fish and other sea creatures in the zone are potentially dead.
A team of German and Canadian marine biologists, for the first time witnessed an area that could be called a 'dead zone' or Dead Zone in the Atlantic Ocean.
This statement is not just issued without a solid foundation. There is a team of biologists who became the first to see this area, the "Death Zone" in the Atlantic Ocean. They are some scientists from Canada and Germany.
This zone of death is an area or area where there is no life in it that can survive. This is because the oxygen content is virtually absent there. In fact, areas with almost nonexistent oxygen have been mentioned even found elsewhere, ie coastal offshore just south and east of the United States. The difference is the discovery of this time is located in the middle of open sea.
It is also discussed in the journal Biogeosciences in the form of papers. The researchers claim that there is a low oxygen bag in the Atlantic Ocean. This area has a large enough area, which is 100 square miles. Even this area turns out to be traveling and seasonal. The largest area ever found has been found in the Gulf of Mexico. This is because the microbes and nutrients are stirred or mixed massively in other places. Zone of death with a large amount of algae is very unique.
Dead zones or dead zones are commonly found in shallow waters, where not a lot of mixing takes place. While the Atlantic ocean is clearly very different, that creates a riddle.
The Dead Zone is often caused by the decay of algae because of the abundance of algae, such as this one off the coast of La Jolla, San Diego, California.
The latest survey shows there are areas located in the North Atlantic, precisely west Africa, which has an oxygen content 20 times lower than originally expected.
The researchers found that the dead zone is disguised as a 'vortex' or otherwise known as 'eddies' which is basically a large oceanic cyclone in a rotating ocean or a vortex, which is no different from how the weather can sometimes do the same thing same as happened in the mainland.

They can spin undisturbed for months. This spinning vortex spin creates a 'wall' around its central core - a process that can rapidly extract oxygen from the region, and as a result, a dead zone or dead zone is finally created.
with the surrounding sea. In addition, the circulation creates a very thin layer of several hundred feet above the swirling water and supports intense plant growth. "
What surprises him and his team is that the rate of oxygen depletion found earlier in the 'dead zone' is deadly: before the study, the general estimate puts dissolved oxygen only about 1 milliliters per liter of seawater.
Karstensen and his team, despite finding the lower end of the spectrum in the Atlantic, contain only 0.3 milliliters of oxygen per liter of sea water. Meanwhile, the oxygen concentration outside the vortex reaches 100 times greater.
patan vortex, chemical concentration, weather pattern and earth rotation.
The researchers are worried that despite being in the middle of the Atlantic Ocean, the existence of 'Dead Zone' or the Dead Zone can even have an effect on people living on land, especially in Cape Verde.
"Given that although some of the 'Dead Zones' we observed are scattered less than 100 kilometers north of the Cape Verde archipelago, it is unlikely that the 'dead zone' in open seas will only hit the island at some point," explains Kartsensen.
"This can cause the coast to be flooded with very low water oxygen levels, which can put heavy pressure on coastal ecosystems and can even trigger the death of fish and marine life or other ecosystems. "
When dead, algae will sink to the sea floor and will be broken down by bacteria. In the decomposition, bacteria need oxygen. Areas with a lot of algae will usually be "Dead Zone" or Death Zone
