Black Sea data. Left: aS0 calculated by Method II (data [73],[74]). The total S0 data in [73] were assumed to represent dissolved ΣS0 because particulate S0 at these depths is negligible [75]. Right: Eh measured by Skopintsev (quoted in [76]) compared to values calculated from aS0 by equation 15. Open triangles are based on evidence for colloidal S0 saturation at the top of the sulfidic zone [77].
