Labrador Sea a key player in providing oxygen for deep North Atlantic life
Researchers from Cornell University have pinpointed the source of oxygen that sustains deep-sea life in the North Atlantic Ocean: the churning waters in the Labrador Sea.
A Cornell University study has identified the Labrador Sea as a vital source of oxygen that sustains deep-sea life in the North Atlantic Ocean. Published in Nature Geoscience, the research highlights the crucial role this region plays in the ocean's oxygen transport system. The Labrador Sea, located between Greenland and Newfoundland, contributes significantly to the strength of the Atlantic Meridional Overturning Circulation (AMOC), the major current system in the ocean.
By mixing oxygen-rich surface waters with deeper waters, the Labrador Sea exports enough oxygen to meet the biological needs of a vast portion of the deep North Atlantic Ocean. This discovery is crucial as global oxygen levels decline due to warming temperatures. The study, led by assistant professor Una Miller, emphasizes that understanding the Labrador Sea's processes is essential to comprehending the future of deep-sea ecosystems, especially in the context of deoxygenation trends.
