Where is the fluorescent beach in Dalian?

Dalian Fluorescent Beach is located in Ganjingzi District, Dalian City.

The beach near Daheishi Village Bathing Beach is about 30 kilometers away from the city center. It has 3.5 kilometers of golden coastline and 160 natural and artificial landscapes. Among them, the famous Moon Bay Bathing Beach is more attractive to tourists.

Every night in mid-April, a large area of ??blue luminous seawater will appear near the Daheishi Bathing Beach in Ganjingzi District, Dalian. From a distance, it looks like a blue galaxy falling into the world. There are two types of fluorescence, one is a continuous flashing green light spot, and the other is a patch of blue light spot. In contrast, blue light spots are more beautiful, but difficult to last. You have to throw rocks into the sea to appear. The sparkling water is mysterious and romantic, like a sea of ??stars.

The beauty of fluorescent beaches has appeared in places such as Puerto Rico, Australia and the Maldives. The phenomenon of fluorescent sea in Dalian is very rare. This may be due to the presence of some special nutrients in seawater, which allows the luminescent microorganisms to continue to glow in this suitable environment.

Causes of the formation of fluorescent beaches:

The fluorescent sea is actually a bioluminescence phenomenon. The so-called bioluminescence phenomenon refers to the process in which organisms convert chemical energy into light energy and release it through certain chemical reactions in the body.

There are quite a variety of bioluminescent species in seawater, ranging from single-cell dinoflagellates, to coelenterates such as luminous jellyfish, annelids such as marine polychaetes, and molluscs such as various luminous cephalopods. Even arthropods such as krill and sea fireflies. Judging from the "fluorescent beach" phenomenon in Dalian, larger jellyfish and cephalopods can be ruled out. Arthropods such as sea fireflies cannot produce such strong fluorescence, so it is most likely caused by the reproduction of single-celled dinoflagellate organisms. .

Dinoflagellates are a very primitive type of single-celled algae. Many of their characteristics are between those of bacteria belonging to prokaryotes and protists belonging to eukaryotes. Currently, they are generally classified as dinoflagellate algae. . The body of dinoflagellates is usually covered by cellulose decks. There are 2-3 flagella in the grooves formed between the decks. The algae rely on these flagella to swim in the water and feed.
