Talking about blue tears by the sea

Recently, there have been many wonders of blue tears on the seaside in Xiamen. Fantastic blue fluorescence is like a star falling into the sea, beautiful and romantic. Blue tears spectacle, also known as "fluorescent sea" or "Martian tide", is formed by the reaction of luminous plankton in seawater after being stimulated.

The rare phenomenon of fluorescent sea has attracted much attention because of its fantastic beauty, and only a few places have been observed. Some cover a sea, such as a dreamy and gorgeous Xinghai; Some meander along the coastline, like a long blue dragon; Sometimes hidden, confusing, covered with a layer of fantasy and mystery.

Recently, this phenomenon has also appeared in many places such as Yaodang Lake in Xiamen and the seaside around the island road. When tourists disturb the seawater, the deep seawater immediately excites blue light, which spreads like a dream with the waves. In the words of tourists, it is "beautiful! The water here can change color! "

When I was in high spirits, I threw a handful of water out, and every drop of water on the surface aroused a blue aperture. Numerous blue apertures, large and small, interacted with each other, flashing and gradually restored calm until the water drops fell. Tourists are deeply moved by the romance of this scene and call this spectacle "Blue Tears".

It is said that art comes from life. Perhaps the inspiration for the blue ocean in the movie Son of the Sea Beast comes from the fluorescent sea. The romantic and mysterious blue water is fascinating because of its strange beauty on the one hand, and daunting because of its unpredictable depth on the other.

If it was in ancient times, the blue fluorescent sea phenomenon might be interpreted as some celestial phenomenon or sign. Now, we are used to seeing the essence through the phenomenon and know that it is actually caused by a luminous plankton in seawater.

Nocturnal algae in seawater contain luciferase and fluorescein. When the sea water is disturbed by waves, the noctilucent will emit light blue light when stimulated, which may be a defensive measure against predators. As the saying goes, "The more charming, the more dangerous".

In addition to the beauty of "blue tears", people are deeply worried about the water quality when this phenomenon occurs. There is a saying that this is one of the precursors of seawater eutrophication, which may form a red tide, leading to suffocation and death of other marine life; There is another saying, on the contrary, the existence of blue tears is a good expression of local ecology. At present, the two views are still colliding fiercely.
