Overview
Research indicates that high pressure in the deep ocean facilitates the extraction of nutrients from organic particles descending through the water column. This mechanism suggests a novel food source for deep-sea microbial communities.
Research Context
Deep-ocean ecosystems, characterized by extreme pressure and limited light, rely on organic matter sinking from surface waters as a primary energy source. The transformation and availability of this organic matter under deep-sea conditions have implications for understanding marine food webs and the global carbon cycle.
Findings
Scientists discovered that extreme deep-sea pressure squeezes valuable nutrients out of sinking organic particles. This process provides an unexpected food source for ocean microbes.
Why This Matters
The finding could rewrite understanding of both deep-ocean ecosystems and how carbon is stored on Earth.
