Finally, scientists have unraveled the mystery of ghostly halo on the sea

Scientists have finally deciphered the 60-year-old mystery called halo, which means that the halo appears scattered on the sea, in images taken from space.

The team of scientists led by Elizabeth Madin at the Hawaii Institute of Marine Biology (USA) finally found the truth about the strange and spooky halo halo that had been a scientific headache for 60 years ago.

The halo appear confusing in satellite images of Earth from the universe. They are scattered in the seas not too far from the shore, radiating miraculous light. Although it has long been trying to find and discover that bare sand rings are located between algae and seaweeds , surrounding coral reefs. However, the way it appears mysteriously in the sea is still a puzzle for decades.

Since the 1960s, a fascinating theory called the grazer hypothesis suggests that halos can be created by hungry organisms that live in coral reefs. To protect yourself from predators in open waters, sea urchins and other herbivorous fish species have used algae as shields, gradually building the enclosure wall of seagrass and sand. However, for decades, no one has observed or verified this hypothesis.

This team has embarked on a multi-year decoding by establishing a series of cameras surrounding a large coral reef near Heron Island (Australia).

As a result, they not only confirmed the "grazer hypothesis" that existed for nearly six decades , but also realized that halo is reporting the health of coral reefs, which humans can follow from space. .

In waters less prone to human hunting and pollution, the halo is usually smaller and more. Not being attacked by humans, many small creatures eat healthy plants, which means there will be many "collective houses" bearing the halo name that exist in that sea. Big carnivores are also not caught, resulting in small fish that are forced to hold themselves in small halo to better protect themselves, instead of leaping into the open waters and creating big halo .

The natural ecosystem guaranteed by human absence means that the coral reefs in that area are secured, because many previous studies have shown that the corals on the earth are being seriously degraded by pollution and moves that upset people's ecosystems.

"This will pave the way for the development of a new solution to monitor large areas of coral reefs, manage healthy coral reef ecosystems and develop sustainable fisheries trends." - researcher Madin said.
