Ocean oxygen: The role of the Ocean in the oxygen we breathe and the threat of deoxygenation
EMB Future Science Brief No. 10 highlights the most recent science on Ocean oxygen, including causes, impacts and mitigation strategies of Ocean oxygen loss, and discusses whether “every second breath we take comes from the Ocean”. It closes with key policy, management and research recommendations t...
