Figure 3From: Formation of Zn- and Fe-sulfides near hydrothermal vents at the Eastern Lau Spreading Center: implications for sulfide bioavailability to chemoautotrophsTotal acid-volatile sulfide (AVS), total Fe and total Zn concentrations in high temperature (> 250°C) vent fluid samples collected along the north-to-south ELSC ridge axis. The bars represent average ± one standard deviation (n = 2 to 5). The average [Fe]T:[Zn]T ratio is also noted for each site.Back to article page
