Bang Saen beach in Chonburi has turned green due to plankton bloom, a common phenomenon in the ocean caused by phytoplankton, microscopic plants that float in the upper, sunlit layers of the ocean. Large numbers of phytoplankton concentrating in one area can cause the color of the water surface to change.
According to a Facebook post of Narongchai Khunpluem, mayor of Tambon Saensuk Municipality as reported by The Nation, the water on Bang Saen beach in Chonburi is expected to return to normal. He said the water on the beach has been green since August 19 because of the plankton bloom.
Naorongchai said the sea has plenty of plankton of the Noctiluca species and the chlorophyll in the planktons turned the sea green.
The mayor also said that though the sea has a strong smell of ammonia in their cells, the plankton is not emitting a toxic substance, therefore, it is harmless.
Many fish had died, added the mayor. Because when the plankton died, they were digested by bacteria and the process reduced oxygen in the water.
Plankton bloom phenomenon has occurred for times this year. The first was in February, then in March, July, and again this month, said the mayor.
This year the plankton bloom phenomenon has occurred four times in February, March, July and again this month, the mayor added.
