The remineralization of organic matter (OM) in Hudson Bay was examined using redox element (Mn, Fe, S, Cd, Re, Mo and U) profiles in six sediment cores. Variation in thickness of surface Mn enrichments and increases in Fe and S in subsurface sediments provide a means to sort sediment cores according...
