What the hell are these huge moving lights in the middle of the ocean?

What the hell are these huge city lights about 200 to 300 miles of the coast of Argentina? Nothing should be there except the dark Atlantic Ocean and a couple of tiny dim lights in the Falkland Islands—Las Malvinas. What are those light formations then?

In the words of NASA: "There are no human settlements there, nor fires or gas wells. But there are an awful lot of fishing boats." Thousands of fishing boats loaded with extremely powerful lights to attract their catch to the surface. So powerful that you can see the swarms from space.


The night fishermen are hunting for

Illex argentinus,

a

species of short-finned squid

that forms the second largest squid fishery on the planet. The squid are found tens to hundreds of kilometers offshore from roughly Rio de Janeiro to Tierra del Fuego (22 to 54 degrees South latitude). They live 80 to 600 meters (250 to 2,000 feet) below the surface, feeding on shrimp, crabs, and fish. In turn,

Illex

are consumed by larger finfish, whales, seals, sea birds, penguins...and humans.

It's an extraordinary show. I'd love to see it in motion from the International Space Station.
