What are blue tears?
Blue tears belong to the ocean." "Red tide" is a phenomenon that can be vividly called "marine blooming period". It is mainly caused by two kinds of luminous marine plankton - "Historia's seafly" and "Noctiluca". The luminescent glands in their bodies will emit light blue light when stimulated by the beating of waves, so when a large number of sea fireflies and noctiluca gather in an explosive manner, a beautiful fluorescent blue sea will be formed, just like tears flowing from the sea.
When do Pingtan Blue Tears appear?
Pingtan Blue Tears usually appear from April to August every year. Among them, noctilucent algae-type blue tears occur from April to May, so now is the early stage of the appearance of noctilucent algae blue tears. Since Noctiluca is a cold-water algae, when the water temperature exceeds its upper limit of survival, the "blue tears" will naturally disappear. The duration of this type of blue tears is also relatively short, usually about 30 seconds, and tear chasers must always be prepared.
July to August is the outbreak point of sea firefly blue tears. The sea firefly itself is larger than Noctiluca, so the particle size of the blue tears will be clearer and brighter. Moreover, the survival time of sea firefly blue tears can reach 120 seconds, making them easier to capture. Depending on the marine environmental conditions, the duration of "blue tears" appearance varies each year, ranging from 1 to 2 weeks to 1 to 2 months.
