What is the fluorescent sea by the sea in Huludao, Liaoning?

65438127 October, a rare fluorescent sea appeared at the seaside of Wanghai Temple in Huludao, Liaoning Province. The waves bring their own magical blue light, which illuminates the beach in Huludao at night. It is reported that the fluorescent sea is actually a bioluminescent phenomenon, which is formed by luminous plankton.

"Fluorescent Beach" is divided into two colors, one is mostly blue spots, and the other is constantly flashing green spots. In contrast, blue spots are more beautiful and dazzling.

At night, there are stars on the winding beach, and couples walk hand in hand, which is extremely romantic. However, such beautiful scenery is hard to last for a long time and will soon fade in a quiet environment. You need to stir the sea water or throw stones to re-glow.

Extended data:

The emergence of "bioluminescence bay" requires three important conditions:

The first one is a shallow bay, which has a small inlet connected with the ocean. In this way, it is difficult for flagellates to get in and out, and the concentration can only be seen by the naked eye when it reaches a certain level.

Secondly, there should be as little pollution as possible in the bay. Flagellates are very sensitive to pollution, and keeping the water clean is extremely important for their survival. Moreover, to see weak fluorescence, it is also required to minimize light pollution on the shore.

The third condition is to have mangroves, because the roots of mangroves can release rich vitamin B 12 and various nutrients, which are essential elements for flagellates to generate light. At the same time, the roots of mangroves can purify water and are important protectors of flagellates.
