| Investigations carried out at a coastal station in the Great Barrier Reef lagoon (GBRL) at Townsville, Australia have shown that the cycling of several trace metals (Fe, Mn, Zn, Cu, Ni, Cd, and Pb) was significantly influenced by the presence of Trichodesmium , a blue-green alga, which throughout the year, frequently forms red tide densities along much of the Queensland coral coast. Whilst decomposition of large masses of Trichodesmium significantly affected metal concentrations, metal speciation changes also occurred, and took place during the presence of senescent Trichoedesmium and high concentrations of humic material (10 mg/l). |

| The methane concentrations within both Holyhead Harbour and Western Irish sea sediments were consistent with the hypothesis that methane was the major component responsible for the acoustic turbidity, which is in agreement with Anderson and Hampton (1980) and Vilks and Rashid (1977). Microcosm experiments indicate that, for Holyhead Harbour methanogenesis may be the major contributor to the methane pool held within the sediment. Furthermore sulphate-reducing bacteria, although natural competitors for the most probable substrates of methanogenesis, may be limited in their activity by sulphate concentrations at the depths where methane is being produced. |
