The study was conducted in 3 mangrove forests in Hurun Bay and 1 in Awerange Bay during the dry season (August 2006) and the wet season (March 2007).Within each forest, meaurements were made for species identification, basal area, diameter at breat heigh. Calculations were made for estimates of stem density and above-ground biomass. Light readings were taken to estimate canopy cover and leaf area index. The extent of tidal inundation was also assessed.Solid-phase elements were measured only during the dry season to determine total C; total N; total organic carbon; total P, Fe, Ca and Mn. Total inorganic carbon was calculated.Rates of sulfate reduction were measured.Solute fluxes of DIC, Ca, Fe, Mn, hydrogen sulphide and O2 across the soil-water interface were measured.Net DIC, Fe, Mn and ammonium production were measured from each plot.Fluxes of CO2 and O2 across the soil-air interface were measured.Nitrogen fixation in soils was also measured. To measure structural and functional attributes of 4 mangrove forests which have colonised fringing coral reefs. Biogeochemical studies were also undertaken in seagrass meadows and sea cage aquaculture sites at nearby locations. Separate metadata records relate to these datasets.
