Xiamen has many wonders of blue tears. What caused this phenomenon?

Blue tears have appeared in many places in Xiamen, so how did this phenomenon happen? Let's talk together today.

In fact, blue tears are caused by a glowing marine plankton. His name is firefly, and the western-style Bay Lake Camp is only three millimeters long. When it emits light, its maximum wavelength depends on the salinity and ph value of water, and the wavelength is between 448 and 463 nanometers, so it also means that the light emitted by fireflies is cold light.

China Taiwan Province Province, Qinhuangdao, Fujian, Zhejiang, Qinhuangdao and other places are the main distribution areas of fireflies. Fireflies can only survive by the energy of seawater, and the survival time after leaving seawater is less than two minutes.

Fireflies have a light-emitting gland in their bodies. When fireflies encounter waves or other stimuli, the light emitted by fireflies will secrete a luciferase and fluorescein, which can convert chemical energy into light energy, but this light energy is very weak, so this weak blue light is produced.

The best time for blue tears is usually from May to August every year. If you want to enjoy it, you'd better go to the seaside on a sunny night, so you have a great chance to see it. The best viewing time is after 10 at night. I went too early to see it. And if it is not before 1 in the morning, it is basically gone. If you want to know whether there were blue tears that night, it is really fate, because besides temperature, weather and other factors may affect the appearance of this landscape.

Although the scenery of blue tears looks romantic, it is really short-lived. Blue tears, as microorganisms in the ocean, need certain conditions for their appearance, such as suitable temperature. They are blue at high tide and low tide, and tears are washed ashore with the waves. When choosing viewing places, it is best to choose some places with long coast, less light pollution and beautiful and pollution-free environment.

You can see blue tears in the following places. One is the Yushan Islands in Ningbo, that is, the Yushan Island in Little Ma Dai, which is known as the first fishing ground in Asia. This island is like a picturesque quiet fishing village, with romantic flowers and Chenda Island in Taizhou. No one came, there was no noise of cars going, there was only reassuring warmth. There is Sanshui Island in Taizhou, also called Hero Island, which faces the canteen across the sea. On the east of the island, there is a gravel beach, which is the best place for sightseeing on the island. There is also Zhoushan Flower and Bird Island, which has a very good Far East 1 lighthouse.
