A centuries-old ocean glow mystery has been solved by scientists from Colorado State University. The phenomenon, known as “milky seas,” has been reported by sailors for over 400 years. Characterized by a vast area of glowing ocean water that can last for months and stretch up to 40,000 square miles, it was previously unknown what triggered this rare event.
Researchers found a relationship between milky seas occurrences and the overlap of monsoon season, which may hold the key to predicting future events. They believe an increase in milky seas events could be associated with deep-water upwelling, bringing nutrient-rich water to the surface during summer monsoon months.
Bioluminescence is the ability of living organisms to emit light, and it’s estimated that 80% of ocean creatures are bioluminescent. However, milky seas are different as they’re a widespread, uniform glow spanning vast areas of the ocean. Scientists think weather patterns may be driving this phenomenon, with changes in wind and currents influencing biological activity.
This discovery brings scientists closer to cracking the code of milky seas, an incredible expression of our biosphere whose significance is still not fully understood. The research provides new insights into unexplored connections between the surface and sky, and microscopic roles of bacteria in the Earth system.
