Description :
Recent models of chemical weathering in alpine glacial meltwaters suggest that sulphide oxidation is a major source of solute in the distributed component of the subglacial hydrological system. The O2 content of glacial meltwaters depends on the initial content of snow and icemelt, which may be controlled by the rate of melting, and the kinetic balance between O2 losses (e.g. sulphide oxidation, microbial respiration) and gains (e.g. diffusion of O2 into solution).
