Additional file 1 of Origin of interstitial water beneath the continental shelf offshore northwestern Australia: insights from hydrogen and oxygen isotope compositions

Supplementary Material 1: Fig. S1 Lithostratigraphy and depth profiles of salinity, major ion (Br⁻, Cl⁻, and Na+) concentrations in interstitial water at sites U1461–U1464. WD: water depth; mbsl: meters below sea level. The dotted line indicates the average chemical composition of seawater: salinity ~35 (Gieskes et al. 1991). Lithology and the major ion compositions are from Gallagher et al. (2017a). For interstitial water classification, see subsection “5.1 Interstitial water classification”
