MIT Identifies Counteracting Effect: Antarctic Sea Ice May Not Cap Carbon Emissions As Much as Previously Thought
 

By Jennifer Chu, Massachusetts Institute of Technology October 1, 2020
 

The prevailing theory has been that sea ice can act as a lid to keep carbon in the ocean from escaping back to the atmosphere. However, researchers at MIT have now identified a counteracting effect that suggests Antarctic sea ice may not be as powerful a control on the global carbon cycle as scientists had suspected.

Study suggests sea ice blocks the flow of carbon both into and out of the ocean, in roughly equal measure.

The Southern Ocean surrounding Antarctica is a region where many of the world’s carbon-rich deep waters can rise back up to the surface. Scientists have thought that the vast swaths of sea ice around Antarctica can act as a lid for upwelling carbon, preventing the gas from breaking through the ocean’s surface and returning to the atmosphere.

However, researchers at MIT have now identified a counteracting effect that suggests Antarctic sea ice may not be as powerful a control on the global carbon cycle as scientists had suspected.
