During measurement at a scan rate of 200 mV s" , the temperature was 80 ± 20 °C. This dramatic fluctuation in temperature makes it impossible to measure concentrations, but the voltammogram clearly indicates that only FeS , Fe(II) and total S(-2) are measurable.

Thus, no significant change in signal could be expected. Figure 2 shows five LSV scans of 0 in ambient 2 °C seawater near the vent site at 2500 meter water depth. The electrochemical analyzer and electrode package shows excellent reproducibility. 3 μΜ consistent with previous results (19). 5 meter above a vent orifice where the temperature was 25°C. At the orifice the temperature was 360 °C as measured by a second thermocouple without electrodes attached. The electrode measurements were thus performed at a safe distance from the orifice.
