Michelle McKeown: Shedding light on the wild world of bioluminescence
Bioluminescent waves illuminating the shoreline
On certain calm summer nights in West Cork, something remarkable happens beneath the surface of Lough Hyne. As paddles cut through the water or fish dart below, the dark lake bursts into shimmering streaks of blue-green light. This dazzling glow isn’t a trick of the moon or a trick of the eye.
