Off the coast of Antarctica, trillions of tons of cold salty water sink to great depths.
As the water sinks, it drives the deepest flows of the"overturning" circulation – a network of strong currents spanning the world's oceans.
Our projections show a slowing of the Antarctic overturning circulation and deep ocean warming over the next few decades. Physical measurements confirm these changes are already well underway.is to blame. As Antarctica melts, more freshwater flows into the oceans. This disrupts the sinking of cold, salty, oxygen-rich water to the bottom of the ocean.
The resulting overturning circulation carries oxygen to the deep ocean and eventually returns nutrients to the sea surface, where they are available to support marine life., 5 kilometers below the surface. These nutrients will be lost to marine ecosystems at or near the surface, damaging fisheries.
