How are the blue tears in Pingtan Island formed?

The "blue tears" in Pingtan Island are formed by noctilucent algae.

"Blue tears" appeared in the waters of Dongmei Village, Pingtan, Fujian. At night, the long coastline glows with blue light, like blue tears under the beat of the waves, which is extremely romantic.

When the tide rises, more noctilucent algae gather on the shore. When a large number of noctilucent insects glow due to the disturbance of waves, fish or ships, the sea is covered with stars and looks like colorful fireworks. This phenomenon is called "sea fire". A large number of luminous insects are put into a bottle, and after continuous stimulation, the light they emit can shine. Formed a "blue tears" phenomenon. Nocturnal algae will glow when stimulated by the outside world, even if they leave the sea and touch them with their fingers.

Enlightenment from "Blue Tears" Event;

The beauty of Blue Tears is what we yearn for. Welcoming the sea, one of the "blue tears", is also called "blue sand" because it is so small that it is almost invisible to the naked eye. After being washed ashore by the waves, it can only survive 100 seconds. With the disappearance of energy, blue light disappears, and its life gradually dies. "Blue tears" are a gift from nature. The disappearance of countless seahawks has brought "blue tears" in just a few hours.

At the same time, "blue tears" are also warnings from nature. Eutrophication of seawater will bring harm to red tide, and relevant departments need to continue to pay attention to the water environment in the area where blue tears appear to prevent red tide.

What we have to do is to appreciate the beauty of "blue tears" and not leave a wound on this beauty. Don't litter, don't pollute the sea, and be a civilized "teary-eyed watchman"!
