Oxygen is critical to the health of the ocean. It structures aquatic ecosystems and is a fundamental requirement for marine life from the intertidal zone to the greatest depths of the ocean.

"The Ocean is Losing Its Breath" presents a summary of scientific experiments, observations and numerical models addressing questions such as how the oxygen content in the open ocean and coastal water changed over the past century and through geological time and what the mechanisms behind this oxygen decline are.
