THE blue glow that has been observed in waves at beaches in eastern Singapore over the past few nights will likely last for the next two to four days, said a marine microbiologist.

The bright blue waves are caused by a bloom of marine microorganisms called dinoflagellates, whose bioluminescence is activated when the waters are disturbed.
