Unique lake

Scientists have found a planet 117 million lakes: the Most unique among them is multi-colored, salty and deadly

The total length of the banks of water bodies on the planet is 250 times greater than the length of the equator.

Estonian and Swedish scientists conducted a study, which was conducted counting all the lakes on Earth. According to a press release from Uppsala University, led the research group of Professor Limnological Institute Lars Sund. He and his colleagues developed a method to automatically find satellite images of all lakes with an area of at least 0.2 ha (about a quarter of the area of a football field).

According to the data obtained on Earth were found about 117 million lakes, covering almost 4% of the surface of the earth’s surface, the subglacial lake in Greenland and Antarctica was not taken into account.

It is noted that the total length of the banks of water bodies 250 times greater than the length of the equator.

The study was conducted in the framework of the project “Color of water”, which examines changes in the composition of organic substances contained in the water.

On the planet there is a considerable number of unique characteristics of the lakes.

So, for example, there are lakes, deadly to all living things, including humans. For example, the lake Continue reading

The Most dangerous lake on the planet

 

The scenic lake Kivu, which is on the border between the Democratic Republic of the Congo and Rwanda, attracted the attention of scientists from all over the world, but the popularity of the reservoir is not linked to its beauty.

Under a layer of water of the lake keeps dangerous deposits of carbon dioxide and tens of billions of cubic meters of methane generated by bacteria in the pond. This deadly combination makes lake Kivu the real bomb. If in these parts there’s an earthquake, deadly ingredients are “mixed” and the lake will simply explode.

Scientists estimate that lake Kivu is a threat to at least two million people who live in a dangerous area. In the event of volcanic activity or earthquake they will be killed by the explosion of methane and of carbon dioxide poisoning.

LAKE KARACHAY, RUSSIA

Lake Karachay is located in the Urals, on the territory of the chemical plant “Mayak”, and is by far the most deadly lake in the world.

In 1951 the lake was used for storage of liquid radioactive waste, and over the past decade there has accumulated about 120 million curies of radioactive materials, mainly cesium-137 and strontium-90. The lake is so toxic that a five-minute Continue reading
