The number of lakes under the ice of Antarctica has increased to 231.
85 new lakes have been discovered under the ice of Antarctica. Now the number of lakes has increased to 231. The new research says that the lakes found under ice of Antarctica can make the danger bigger by increasing the sea level. The new lakes found here are at a depth of several kilometers near the surface of the South Poll. It has been discovered with the help of the Cryosat satellite of the European Space Agency. This claim has been made in the published research in the journal Nature Communication.
The height figures of a decade found from the Cryosat satellite were analyzed. Scientists detected small changes that occur during the filling of lakes and during drying. During this time rare information about Antarctica’s water system was found.
How was it revealed?
Sally Wilson, researcher at Leeds University, says that during this time five such networks were also detected which are connected to lakes. It is difficult to detect such subglesal lakes because they are buried in the depth hundreds of kilometers below. It is difficult to monitor these lakes filling and drying up. It takes from several months to years.
She says the Cryosat Mission was launched in 2010. Its satellite recorded a change in ice thickness and height over Antarctica. Using radar ultimatry, small changes related to the activities below were monitored.
Researcher and Professor of Leeds University Anna Hogg says that it was interesting to know that these lakes could change during waterlogging or drainage cycles. This shows how much is there in Antarctica. Therefore, these lakes to be developed in the future should be monitored.

What a big danger this?
This research helps in understanding the migration of water under the ice sheet. According to Sally, many models are used to estimate the increase in the water level of the sea due to snow, but it is not mentioned by lakes.
The new research will help to understand what kind of process the flow of water under Antarctica changes. Such lakes are formed by the accumulation of melted water due to friction caused by the heat of the ground and the friction arising from the snow. The friction can decrease due to the timely filling and emptying of these lakes, causing ice to move towards the sea rapidly and affect the water level of the world worldwide.
Experts say that water has been lying separate in such lakes for millions of years. There can be such microorganisms, bacteria or viruses that can be unknown for humans. There may be a threat to humans.
Such lakes allow water to flow rapidly under the glacier. This process can increase the water level of the sea by making it unstable the snow sheet. If this continues to happen then there will be a threat on a large scale.
Recently, researchers at the University College, Cork, Cork in Ireland and Barcelona University in Spain, surprised the locations hidden in Antarctica. It was claimed that the depth of some underwater valley is more than 4 thousand meters.
