There is a growing consensus that the open ocean is losing oxygen overall with a very likely loss of 0.5 − ,3,.,3,% between 1970–2010 from the ocean surface to 1000 m (medium confidence). Globally, the oxygen loss due to warming is reinforced by other processes associated with ocean physics and biogeochemistry, which cause the majority of the observed oxygen decline ( high confidence ).

When the A‐MBR system was bubbling with 10% CO 2, nitrogen removal capacity increased from 2.6 ± 0.4 g m −,3, d to ,3,.6 ± 0.4 g m −,3, d. Moreover, membrane fouling was reduced in the A‐MBR system with CO 2 addition, possibly because of overcoming mineral precipitation on the membrane due to lower pH.
