From: Characterization of water masses around the southern Ryukyu Islands based on isotopic compositions
δ18O–δD cross-plots for seawater on the Okinawa Trough (a, b) and Pacific (c) sides of the study area. a Cross-plots for < 433 m depth; b, c plots for seawater collected from all depths. Outliers for which δ18O and/or δD values are not within the mean ± 2σ range for individual water masses are not shown. For abbreviations, see Fig. 3
