Short summary
Here we studied how tiny polar ocean plankton (foraminifera) breathe, using micro-sensors and 3D imaging to see if their respiration changes in responds to climate and environmental change. We found that the dominant polar species, Neogloboquadrina pachyderma, exhibits metabolic stability across large changes in temperature and ocean chemistry. This suggests its shell chemistry is not strongly affected by metabolism, supporting its use for reconstructing past polar ocean climates.
