The sea water just touches emits blue light

This rare underwater optics makes many people think of images only in sci-fi films.

Optical in nature is an extremely interesting and wonderful scientific phenomenon. We have become accustomed to the "Nothern Lights" numbness, the aurora that transforms the northernmost sky into a spectacular performance. However, no need to go so far, you absolutely can enjoy the beauty of nature in a sea off the coast of Tasmania, the state is considered Australia's paradise.

Earlier this year, the online community, especially those who love travel, love exploring nature, handed over many images of rare and wonderful natural optical phenomena occurring in a sea area. Western Australia. In the photos, one can see a sea of ​​water strewn with clumps of water as if it is capable of producing very magical light.

When you throw a stone in the water, it immediately turns blue and then dissolves.

Even step into the water.

The water suddenly turned blue, miraculously like magic.

Explaining this amazing natural phenomenon, the scientists say these bright spots appear to be due to the concentration of billions of glowing single-celled and planktonic algae . They are disturbed by currents and are brought ashore by waves.

Photographer Brett Chatwin, a man who has lived a long life in this waters, is one of those lucky enough to witness this amazing natural sight. For him, it was the first time in his life that he saw firsthand such a phenomenon occurring in the waters he lived in.

When night falls, the beach changes to a bright blue.

Speaking to the Advocate in an interview, he said: "It is great to see the waves that carry piggyback on the back of the blue electric shimmer. It is unknown when this phenomenon will appear but it will certainly make a big contribution to the development of the local tourism industry , " he added.

The sea glows in the night.

Current currents and warming of water affect the appearance of this optical phenomenon.

The professor of aquatic plants at the University of Tasmania, Gustaaf Hallegraeff, said this bioluminescent phenomenon reappeared in 1860 in Sydney Harbor after a long time of disappearance. By 2000, it was discovered that it "drifted" along the sea to the south, however, it now appears in Tasmania and is here for a long time.

"We have some evidence that ocean currents and warming of water in the ocean are factors that affect the appearance of this underwater optical phenomenon, in about 20 years. , we predict, it will appear with a thicker frequency , " Professor Gustaaf said.
