Deep-sea pressure unlocks hidden nutrients from sinking particles, study finds

Scientists have discovered that extreme pressure in the deep ocean squeezes nutrients out of marine snow, the tiny particles of dead algae and organic matter that sink from the surface. This process provides an unexpected food source for microbes living in the deep sea. The findings also indicate that more carbon escapes into deep ocean water than previously thought. This could significantly alter current understanding of Earth's carbon cycle. Researchers believe the discovery will help improve the accuracy of future climate models.
