What Kind of Sound Does Photosynthesis Make? Apparently, It Goes Ping.

If you imagine what an underwater scenery is like, you would probably see hues of blue and green with some light peeking through, various plants and animals filled with color and life, and the soothing sounds of the sea. But, amidst all of that, we have the tiny organisms called algae which also photosynthesize.

Underwater, that process of converting sunlight and carbon dioxide into energy and oxygen sends tiny bubbles spiraling toward the surface. And according to new research, when each bubble detaches from the seaweed, it goes ping. The scientists behind the discovery suggest that, like a heartbeat heard through a stethoscope, measuring that unique sound could be a new way to monitor the health of a coral reef.

Listen to the faint sound of the bubble produced by photosynthesis on Sarah Keartes' article at Hakai Magazine.
