Figure 7. Sulfate vs. sediment depth. A. Gorda Transect. Symbols (from onshore to offshore) are solid square = Site 1019; open square = Site 1022; open circle = Site 1020; and solid circle = Site 1021. B. Conception Transect. Symbols are solid square = Site 1017 and solid circle = Site 1016. C. Baja Transect. Symbols are solid square = Site 1011 and solid circle = Site 1010. D. Coastal Transect. The inshore sites of the three onshore-offshore transects are included in this panel as well. Symbols (from north to south) are solid square = Site 1019; solid triangle = Site 1022; solid diamond = Site 1018; solid circle = Site 1017; open square = Site 1014; open triangle = Site 1013; open diamond = Site 1012; and open circle = Site 1011. Note that the slight increases in sulfate in the deepest samples of Sites 1020 and 1016 are likely because of a small proportion of contamination by drilling fluid.
