Introduction Supplemental Table 1 presents the station number, location, depth, potential density (sigma theta), oxygen concentration (micromol/kg), percent oxygen saturation ([O2]/[O2]sat*100), and delta18O of dissolved O2 (‰) for the 77 SAVE-2 samples analyzed in this study. The four samples with anomalous [O2] relative to the SAVE-2 Winkler [O2] data have been excluded. The isotopic reference for O2 is air. 2007gb003162-ts01.txt Save-2 samples: Station number and location, and sample depth (m), density (sigma), oxygen concentration (micromol/kg), oxygen saturation (%), and delta18O (‰).
