The strange sight of blue tears has appeared in many places in Xiamen. Experts went to the local area to study and found that it was caused by fluorescent phytoplankton algae.
In 2021, many things have impressed people in China. The first thing is that the epidemic has not ended, but China has completely controlled the epidemic. This is still the case in the world. None of them have been done. The second thing is the sand and dust weather in northern China, which is still fresh in people’s memories. There were two sand and dust weather events in March this year, and the last one will enter 2021. After that, the Xiamen area The spectacle of blue tears has appeared in many bays. Today I will talk about these blue tears.
When many people hear blue tears, the first thing they think of is the blue sun in Beijing and other places, but the two are not related. Blue tears are a type of sun that appears in the coastal waters of Xiamen According to expert research and inspection, this phenomenon is caused by the luminescence of a type of phytoplankton algae.
In February and March this year, blue fluorescent seawater appeared in some coastal seawater and individual lakes in Xiamen. Netizens called it blue tears. It was very strange and beautiful, just like Just like fluorescence sprinkled on the sea, the blue light ripples in the water, constantly changing its shape, like dancing, like the blue stars falling in the water.
According to the explanation of relevant experts, this is produced by a kind of phytoplankton in the water. It is a kind of fluorescent algae. Its name is also called "blue tears". It can be said to be a very surprising species, but this fluorescent algae is not harmful to water bodies, but is food for many fish.
This kind of algae is very small. It gathers together during reproduction and is brought to the waters of Xiamen, China by ocean currents. The reason why this kind of algae can glow is because it contains blue pigment and fluorescence. The enzymes are washed close to the coast by the sea water. Due to the stimulation of the waves and current factors, they will emit a faint blue light. When they gather together, it is what we call the spectacle of blue tears.
