Is deoxygenation detectable before warming in the thermocline? [PDF]
Biogeosciences, 2020 Anthropogenic greenhouse gas emissions cause ocean warming and oxygen depletion, with adverse impacts on marine organisms and ecosystems. Warming is one of the main indicators of anthropogenic climate change, but, in the thermocline, changes in oxygen ...

Ocean deoxygenation: Past, present, and future
Eos, Transactions American Geophysical Union, 2011 To a first order, the oxygen content of the ocean interior is determined by the influx of the gas across the air‐sea surface (i.e., ventilation) and consumption due primarily to microbial respiration. As these two competing processes vary in space and time, so does the concentration of oxygen in the ocean interior.
