Physicochemical attributes of Washburn (WS) and Heart Lake Geyser Basin (HL) hot springs.
| Site | Temperature (°C) | Source Gases (%) | |||
|---|---|---|---|---|---|
| pH | CO2 | H2 | CH4 | ||
| WS0 | 64 | 6.5 | 93.81 ± 2.93 | 2.42 ± 0.09 | 6.00 ± 0.19 |
| WS1 | 77 | 5.8 | 85.21 ± 5.40 | 2.94 ± 0.05 | 4.82 ± 0.08 |
| WS3 | 91 | 7.0 | nd | nd | nd |
| HL9 | 61 | 8.6 | 3.76 ± 0.19 | 0.01 ± 0.00 | 1.18 ± 0.02 |
| HL10 | 34 | 8.2 | 31.66 ± nd | 0.02 ± nd | 0.75 ± nd |
| HL11 | 73 | 8.5 | nd | nd | nd |
Temperatures and pH values are listed for each hot spring sampled at WS and HL. Geothermal source gas bubbles were captured and analyzed for the presence of CO2, H2, and CH4 (±values are equal to the standard deviation of the mean percentage value based on quadruplicate resampling). Time and weather constraints prevented replicate sampling from being collected at HL10. Collection of source gases was not possible at WS3, which is not fully submerged in spring fluid, and HL11, which did not produce observable bubbles (nd = not determined).
