Underwater Internet and how sharks chew on it

99% of international data is transmitted by cables lying on the ocean ground and called submarine communications wires. Internet in the saltwater... How? The Internet in regular water already sounds crazy, right? Okay, fewer emotions - more facts. Wires length distances hundreds of thousands of miles, and some of them are placed at a depth of 9 km.

How is it put there? Science!

Cable establishment is carried out by specialized stacking ships. They not only drop the cable with the cargo connected to the bottom but also ensure that it passes only on a flat surface, avoiding coral reefs, wreckage debris, and other common barriers.

The width of the classic wire is around 6 cm, but the deep-sea cables are much thinner - as a simple marker. The difference is explained by the usual vulnerability factor -not much happens at a depth of over 2 km, so the cable does not need to be covered with a galvanized shielding layer. Wires placed at shallow depths are buried at the bottom using directional jets of water under high pressure. Although the value of putting one mile of the submarine wire varies depending on its entire length and purpose, this process always costs hundreds of millions of dollars. But even then, underwater Internet wires are quicker and cheaper than satellites. Obviously.

Sharks part

When you can't connect to the Internet, there is a 0.0001% chance that in sea one shark is trying to eat it. Why? Possibly this is somehow related to electromagnetic fields. Or sharks are just curious. Or mean. Oh! I got a theory! Perhaps in such a way, sharks are trying to destroy our communications infrastructure ere a land invasion. Yeah. Sounds reasonable. 

To be honest, I don't know why sharks do such a thing. Well, it's not just me, even scientists do not know why sharks enjoy biting underwater wires. Anyway, the fact that sharks actually chew on our Internet is hilarious. Sometimes they are even successes and damage the insulation of wires. (Should we go back to my invasion theory?) Anyway, to avoid Internet chewing, "big fish" companies as Google cover their communications with a protecting Kevlar sheet. 

1: 0 in favour of Google. It remains to wait for what the sharks will answer to this.
