Figure F33. Sulfur chemistry of interstitial water samples across the upper 40 m, Site U1426. A. Sulfate concentrations from squeezed interstitial water (IW-sq) and Rhizon samples along with headspace CH4 concentration. B. HS– concentrations from squeeze and Rhizon samples along with headspace CH4 concentrations. Note that CH4 values are not meaningful at depths where CH4 surpasses saturation at 1 atm pressure.
