Antarctica s ice free lake Why Antarctic lakes are ice free lakes

In 1960, the Japanese scholar Torii Iron analyzed the measurement data and found that the water temperature under the thin ice on the surface of the lake was about 0, and the water temperature continued to increase as the depth increased. At a depth of 16 meters, the water temperature rises to. This temperature has been maintained steadily to a depth of 40 meters.

Below 40 meters, the water temperature rises slowly. At a depth of 50 meters, the increase in water temperature suddenly increases. At a depth of 66 meters, the water temperature is as high as 25, which is not much different from the surface water temperature of the East China Sea in summer.

In 1974 and 1976, scientists found that in the ice world of Antarctica, there is an ice-free lake with an area of about 10,000 square kilometers. This lake is hidden from time to time. In 1981, the former Soviet Union and the United States sent a 26-member Antarctic expedition.

They searched for the location of the lake as shown on Sputnik**, but they couldn't find it. The team members only found countless bubbles with high temperatures in the waters of the ice-free lake.

This strange phenomenon aroused great interest among scientists, who investigated it in depth and put forward various opinions.

Some scientists have suggested that this is the result of the interweaving of air pressure and temperature under special conditions. They believe that in the Antarctic region, the water temperature is higher than the temperature on the ground because the sea water at a depth of 500 meters does not come into direct contact with the cold air. This temperature difference causes the sea to move vertically, creating a whirlpool.

With the power of this whirlpool, the sea water at a depth of 500 meters is swept to the surface of the sea, forming an ice-free lake.

Another view is that in the coastal areas of Antarctica, there are some peculiar saltwater holes. These saltwater holes emit heat, which condenses into huge blocks of ice. When the weight of the ice is too large, it sinks to the bottom of the sea.

Frozen lakes are formed by the squeezing of huge ice masses, which are warmer at deeper depths and rise to the surface. After the lake water came into contact with the cold air for a while, the lake water formed large ice cubes again, and the frozen lake disappeared again.

Some scientists even believe that there is a secret base built by aliens under the ice in Antarctica, and that the heat emitted by them melted the ice here. Other scientists point out:

It's a warm lake, and it's likely that there's a big hot spring under the water that raises the temperature and melts the ice.

There are many different views on this question, and there is no convincing answer yet.

Because that's the heart of Antarctica.

Its heart is always hot.

Tell us not to be too cold.

Hehe, I digress.

Ten kilometers west of Lake Vanda in Antarctica, there is a small lake. This small lake does not freeze at -50, and people call it "Tongpan Lake". Tangpan Lake is very small, with a diameter of several hundred meters; And the lake is also very shallow, only 30 centimeters.

The water in Tongpan Lake is relatively salinity, and if you splash a glass of lake water on the ground, a thin layer of salt will appear in the blink of an eye. Scientists have observed that Tompan Lake does not freeze even when it reaches -57, so people call it "the lake that does not freeze". So, why doesn't this lake freeze?

Some people will say that because the salt content of the lake is relatively high, it will not freeze. Some scientists say that the problem is not so simple, and that the fact that the lake does not freeze in such cold conditions may be due to the geothermal heat around it.

Because of the relatively high salinity and the abundant geothermal resources nearby, it does not freeze in cold weather. 14 million square kilometers of Antarctic land is almost entirely covered by a few hundred to several kilometers of hard ice. The temperature here has reached minus 50 degrees, and everything here has lost its vitality.

However, in this snow-covered place, scientists unexpectedly discovered thawed lakes.

This unfrozen lake covers an area of more than 2,500 square kilometers. In 1960, Japanese scholars analyzed and measured the data and found that the water temperature under the thin ice layer of the lake was about 0. As the depth increases, the water temperature keeps rising.

At a depth of 16 meters, the water temperature rises to. The temperature has been steadily maintained at a depth of 40 meters. Below 40 meters, the water temperature rises slowly.

At a depth of 50 meters, the water temperature suddenly rises. The bottom of the lake is 66 meters deep, and the water temperature is as high as 25, which is almost the same as the surface water temperature of the East China Sea in summer.

Some scientists believe that this is the result of a mixture of air pressure and temperature under special conditions。They believe that in the Antarctic region, the water temperature is higher than the ground because the sea water at a depth of 500 meters is not in direct contact with the cold air. This temperature difference causes the seawater to move vertically, creating eddies.

Under the action of this whirlpool, the sea water at a depth of 500 meters rolls to the surface of the sea, forming an unfrozen lake.

Another point is that there are some special saltwater caves in the coastal areas of Antarctica. These saltwater caves emit heat that condenses into huge blocks of ice. If the weight of the ice is too large, it will sink to the bottom of the sea.

Under the pressure of huge ice blocks, the warmer sea water at deep depths rises to the surface, forming an unfrozen lake. After the lake has been in contact with the cold air for a while, the lake has formed a large ice block, so there is no freezing? The lake is gone.

Many scientists speculate that aliens have established secret bases in Antarctica. Even some scientists believe that there is a very likely secret base built by aliens under the Antarctic ice. The heat energy they release at the event site melts the ice here.

Other scientists have pointed out that this is a warm lake, and it is likely that there is a large hot spring underneath it to raise the temperature of the water and melt the ice.

The debate about non-frozen lakes in Antarctica continues, but so far no one has found an answer that convinces everyone. As a result, exploration continues in the hope of finding out why the lake is not frozen.

The millennium-free lakes in Antarctica do not freeze because the freezing point of the lake is too high.

Why doesn't the Antarctic "frozen lake" freeze, and what is the truth about scientists' alien secret bases?

The temperature in this place is not very low, so it is said that it will not freeze.

I think it's probably because it has a lot of salt in it, so it doesn't freeze.

It may be that there is a lot of stuff in the sea in that place, so it doesn't freeze easily.

Antarctica's 14 million square kilometers of land are almost completely covered by hundreds to thousands of meters of ice, where the temperature reaches minus 50 degrees Celsius, and everything is devoid here. However, in this icy and snowy place, scientists unexpectedly discovered an ice-free lake. This ice-free lake covers an area of more than 2,500 square kilometers, and there are no human footprints here, and life is extremely rare.

Even more surprising is that there is not only one such lake in Antarctica, and the former Soviet expedition team used radio wave devices to discover nine more ice-free lakes under the ice up to 3,000 meters thick near their base.

This is a puzzling question. Geologists have found that there is no volcanic activity around the lake. The water of the lake is no different from any other water on the earth's surface. Why didn't the water solidify into ice under such conditions?

Some scientists believe that this is the result of a mixture of air pressure and temperature under special conditions. Based on the relationship between air pressure and the thawing point of solids, these scientists explain the mystery of the ice-free lake from the perspective of the special pressure on the water of the Antarctic lake. Indeed, under more than 3,000 meters of ice, the pressure on the lake can reach 278 atmospheres.

Under such intense pressure, the ice melts at around minus 2. At the same time, the ice layer can effectively prevent the heat from being dissipated, so that a large amount of ice in the recess of the Antarctic continent will melt and become "lake water". However, this argument has been refuted, because if this is the case, then all the lakes in the Antarctic region should not freeze, so why is this the case here?

Some other scientists believe that there is a large hot spring under the water of this "warm lake", which has raised the temperature of the water and melted the ice. However, this view has been questioned by other scientists because it is not properly verified.

To this day, no one has been able to come up with a convincing example to prove this view.

Some scientists speculate that the lake is actually heated by the sun. They believe that the lake, surrounded by icebergs, is actually a pool of stagnant water, and its heat is difficult to dissipate.

The ice here acts like a lens that focuses the sun's rays and acts as a source of heat on the lake. Over time, this ice-free lake on the glacier has been formed. However, this view has been challenged in a similar way to the first one.

Cosmologists then came up with the "alien theory", which suggests that there is a high probability that there is a "secret base" built by aliens under the ice in Antarctica, and that the ice is melted by the heat emitted by their activity sites. However, there is not enough evidence to date whether there are aliens in Antarctica.
