Dalian is now a large "luminous beach" as far as the stars
The sea is not only romantic but also interesting. Amazing: big black stone now "luminous sea" blue light dot green light dot starlight piece. Experts who know photoluminescent film say this phenomenon may be caused by the accumulation of luminous microorganisms in the sea. On the evening of the 16th, the reporter visited the site and found that the big black stone seaside. It was really shining at night, just like the "star river", which attracted many nearby citizens and college students to come and have a look. Experts from dalian ocean university said the luminous sea may be caused by the accumulation of luminous microorganisms in the seawater, which continuously emit light.
Scene: seawater glows like "starry sea"
Luminous light from photoluminescent film is divided into two kinds, one is a continuous flashing green point of light, and the other is a patch of blue point of light. Blue spots, by contrast, are more beautiful but less sustainable. Stones must be thrown into the sea to appear. The twinkling sea is mysterious and romantic, just like the starry sea.
"In fact, the last few days in this area of the sea luminous more beautiful, larger scale." Wang, a university student near the big black rock, said he had been to the seaside for three days to watch the 'starsea'. "
A few days ago, the luminous light came with the waves to the shore. Wang said that in recent days, more and more people have been watching the beach, and the mysterious fluorescence in the sea seems to be "shy" and gradually fade away. "But still beautiful!
Explanation: luminous microorganism makes
"luminous sea"
Reporters learned in the interview, the luminous sea beauty in Puerto Rico, Australia and the maldives and other places have appeared, attracting many tourists.
Opinions vary on the cause of the luminous sea. Wang bin, a teacher at the college of Marine science and environment at dalian ocean university, believes that the luminescence of seawater is usually due to the aggregation of flagellum and other luminescent microorganisms in seawater.
"These self-luminous
algae or bacteria fluoresce when the surrounding environment is suitable. To determine which microbes are glowing, we need to collect seawater samples and carry out specific observation and analysis in the laboratory." Wang bin said that it is rare to see a night sea in dalian. It may be
presence of a particular nutrient in the water, which allows the bioluminescent microbes to glow continuously in the right environment.
