Resumo: | Sediment cores 40 cm depth were taken in triplicate at nine points along an unvegetable intertidal flat, to assess the ecological implications of sedimentological characteristics. Each core was sectioned in 5 cm depht layers. In these sub-samples temperature, pH, water, organic matter and carbonate content were determined. Granulometric analysis, porosity, qualitative and quantitative identification of sediment components were also carried. The sediments presented low water (15.6 - 37.2 %), organic matter (0.7 - 5.0 %) and carbonates (0.3 - 1.0 %) contents, prevailing fine to very fine sand at surface. Statistical analysis showed a strong horizontal homogeneity regarding sedimentological and physiochemical parameters. Organic matter exhibit a general trend of increase with depth, while carbonate content follow an inverse behavior, refleting the higher contribution of bioclastic calcareous. Textural features and qualitative sediment analysis suggest that the biological mechanism of shell crushing is predominant over physical ones in the grinding till sand size. Amongst the involved organisms there is a sponge Clione celata, the mollusks Nassarius vibex and Thais haemastoma floridana (Gastropoda), Martesia striata (Bivalvia), and the spionid polychaete Polydora socialis and P. websteri. |
