Experts explain Fluorescent sea phenomenon is caused by the dinoflagellates glow Prove that the recent sea high cleanliness

"Dalian sea appear this kind of phenomenon is likely because the water there was some kind of special nutrients, makes light-emitting microbes in the appropriate environment continues to glow. Of course, the ocean climate, ocean currents, nitrogen, etc are all contribute to the cause of the phenomenon. Such as dalian sea water temperature is relatively high this year, and now is the time to reproduce these algae."Cai Hengjiang further explanation, crucially, the sea pollution condition improved a lot, and now this season, visitors to the beach is relatively small, cleanness of the water is relatively high, "dinoflagellates is sensitive to pollution, once water pollution, they will die. In addition, near the light pollution is poorer, also is the main reason that appear fluorescence sea phenomenon."

There are three elements of bioluminescent bay to produce

Is a shallow bay, there are very small and the ocean and water entry.So, dinoflagellates almost exclusively in not out, concentration gathered to a certain extent, can be visible to the naked eye.The gulf should have less pollution, dinoflagellates are sensitive to pollution.Surrounded by a mangrove forest, the root of mangrove can release rich vitamins and a variety of nutrition elements, these are the dinoflagellates and brightening essential elements.
