What exactly are these structures under Antarctic glaciers called “Fingers of Death”?

As can be seen from the given name, these structures represent the Antarctic seas and seas. has a negative impact on glaciers. So much so that these structures have an unusual structure.

Bride, Details about the fingers of death let’s see.

Researchers have discovered that these creepy fingers of death are crawling beneath the Antarctic ice to the seabed and freezing everything they touch.

Although these fingers of death give the same feeling as an alien invasion movie with long fingers, thankfully there is no alien activity involved here. This is an ice cube with salt water that grows in a few hours. That is, bricinula.

When sea ice forms, the salts in the seawater do not become part of the structure. Instead of, does not freeze due to the high salt content in the ice, They form pockets of cold, salty water.

If you get a chance to escape to the water below, this salty water will sink.

In other words, this salinity makes it much denser than the water it enters. As the saltwater flow decreases, the seawater around it freezes and thus are formed pools of salt water, even fingers of death.

Bricinules, also called icicles, form when they reach the seabed. It can continue to spread, causing the ground and everything above it to freeze. This is why this formation is called fingers of death.
