Marine breathing plays on the climate

A research group of the IFM-GEOMAR, institute for marine sciences of the community Leibniz, publishes in the last edition of Science the conclusions of works according to which the ocean "breathes". Kiel scientists have used exclusively in the sea of
Labrador, a measuring robot with oxygen sensors.

Research, carried out as part of an international project, shows that in winter, this sea "inspires" large quantities of atmospheric oxygen. Like a lung, the Labrador Sea seems to feed much of the deep Atlantic Ocean into oxygen. The measurements also show that absorbed oxygen is rapidly redistributed through ocean currents throughout the ocean.

This could have significant consequences for climate research because oceanic oxygen concentration is closely related to that of the atmosphere. This discovery opens the way for new research on climate change.
