This data set provides measurements of oxygen to argon molar ratios from discrete samples collected within the mixed layer at the long-term sampling site (Station ALOHA) of the Hawaii Ocean Time-Series program, within the North Pacific Subtropical Gyre, between November 2013 and January 2019 (near-monthly cruises). Samples were measured by membrane inlet mass spectrometry following Ferrón et al. (2015). Version 2 had corrected longitude data (in decimal degrees east). Version 3 includes a new file with estimated rates of net community production, gross oxygen production and community respiration for the mixed layer.
