The Ocean's Biological Pump: In Situ Oxygen Measurements in the Subtropical Oceans

open access: yesGeophysical Research Letters, 2022
The magnitude and distribution of the ocean's biological pump (the downward flux of organic carbon (OC) from the ocean surface) influences the pCO2 of the atmosphere and the O2 content of the deep sea, but has not been well quantified.
