AbstractSea water samples collected above, within and below a pronounced oxygen minimum were analyzed for their Mn content. Amounts of dissolved Mn slowly decreased with depth and little, if any, relationship with oxygen was found. In contrast, suspended particulate Mn values increased markedly at the top of the oxygen minimum. Concentrations of weakly leachable Mn probably resulted from microbial oxidation. Labile Mn fluxes, measured with particle interceptor traps at depths of 125, 275, 525 and 900m slowly increased with depth. These rates are the same order of magnitude as those estimated for excess Mn accumulating in open-ocean sediments, which implies that biogenic transport is a major factor in the oceanic cycling of Mn.
