- All fluids were collected using isobaric gas-tight fluid samplers (Seewald et al., 2002).
- Temperature was measured during sample collection using a type-J thermocouple attached to the inlet snorkel. Reported values are maximums observed during sample collection.

Analytical methods:
pH: Ag/AgCl combination reference electrode
Na+, K+, Ca2+, Mg2+, Cl-, Br-, SO42- : ion chromatography with suppressed conductivity detectionCH4: gas chromatography with flame ionization detection
H2: gas chromatography with thermal conductivity detection
