Última Methane Emission, Sulphide Concentration and Redox Potential Profiles in Mtoni Mangrove Sediment, Tanzania OceanDocs Lyimo, T.J.; Pol, A.; Op den Camp, H.J.M.. Mangrove forest sediments were investigated with respect to organic matter content, bacterial numbers, methane emission, sulphide concentration and redox potential profiles. The sediments had characteristically high organic matter content (varying from 8 to 30 % of dry weight) and high bacterial numbers (varying from 5 to 20 x 10<sup>8</sup> cells/g fw). Both values decreased with depth (0-30 cm). Methane emission, sulphide and redox profiles on the other hand, showed remarkable differences between and among sampling sites. In areas with a high abundance of leaf litter and few trees very high sulphide concentrations were encountered: increasing from about I mM at the surface to 25 mM at 30-40 cm depth. Redox values were consistently low; from...
