Measurements of oxygen to argon molar ratios at Station ALOHA

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). This version has corrected longitude data (in decimal degrees east).
