Baselines Matter: Mass Spectrometric Assessments of Biological O2 Supersaturation (ΔO2:Ar) Benefit from Two-Point Calibrations

Introduction Click to copy section linkSection link copied! Mass spectrometric measurements of the ratio of oceanic Oxygen (O2) and Argon (Ar) are becoming a widely applied tool in biogeochemical research to estimate local and regional net community productivity (NCP) and draw conclusions regarding ecosystem functioning.
