The Ocean Takes a Deep Breath

Arne Körtzinger,* Jens Schimanski, Uwe Send, Douglas Wallace

Deep convection is the major mechanism for replenishing oxygen in the deep interior of the world ocean, and its variability affects the use of atmospheric oxygen to monitor the global carbon cycle. Sensors mounted on autonomous floats allow this episodic breathing of the ocean to be monitored in near real time. The results suggest that the tools are available now to make oxygen a key parameter in marine global change research.
