Thailand’s fishermen fight extreme bright-green marine ‘dead zone’: ‘this is the first that I’ve seen it so bad’

An unusually dense plankton bloom off the eastern coast of Thailand is creating an aquatic “dead zone”, threatening the livelihood of local fisherman who farm mussels in the waters.

Marine scientists say some areas in the Gulf of Thailand have more than 10 times the normal amount of plankton, turning the water a bright green and killing off marine life.

“This is the first that I’ve seen it so bad,” said marine scientist Tanuspong Pokavanich. “It is very severe.”

Plankton blooms happen one or two times a year and typically last two to three days, experts say. They can produce toxins that harm the environment, or they can kill off marine life by depleting the oxygen in the water and blocking sunlight.
