NASA has found a new iceberg the size of London

Scientists from the NASA Earth Observatory showed a future iceberg, which was formed due to the many kilometers cracks in the Brunt Ice Shelf. Ice Block affects primarily by its size: according to the researchers, an area of ​​1, 7 thousand square kilometers. This is comparable to London or a small area of ​​countries in Africa (Mauritius). Details are reported on the organization's website.

Now on the Brunt Ice operates the world's first fully mobile Arctic station - Halley VI. The latter will have to change their position, because as soon as the two cracks on the glacier unite, it will break away from a huge iceberg, which will be the largest in the history of observations of this object. crack propagation velocity is about 4 kilometers per year.

Trace the movement of cracks can be due to the photographs taken in 1989 and in January 2019.

Research Brunt Ice started in 1915, research stations working on it for more than 60 years. Because of the cracks have moved the Halley VI three years ago. It is possible that this time again need to shift the Arctic station.

The Antarctic ice sheet in 2017 lost more than 250 billion tons of ice. In the next few decades, the melting of ice in Antarctica could add to global sea level rise of several meters. It may seem that the ice is still a lot, but in fact the loss is already catastrophic. To blame for climate change, which leads to a sustainable reduction in the mass and area of ​​Arctic sea ice.
