Records of sedimentary dynamics in the continental shelf and upper slope betwee...
Martins, V.; Abrantes, I.; Grangeia, C.; Martins, P.; Nagai, R.; Sousa, S. H. M.; Laut, L. L. M.; Dias, J. M. A.; Dias, J. M.; Silva, E. F. daThe sedimentary unconsolidated cover of the Aveiro–Espinho continental shelf and upper slope (NW Portugal) records a complex interplay of processes including wave energy and currents, fluvial input, sediment transport alongshore and cross-shelf, geological and oceanographic processes and sediment sources and sinks. In order to study this record, a set of surface sediment samples was studied. Sediment grain size...
The response of benthic foraminifera to pollution and environmental stress in R...
Martins, V.; Yamashita, C.; Sousa, S. H. M.; Martins, P.; Laut, L. L. M.; Figueira, R. C. L.; Mahiques, M. M.; Silva, E. F. da; Dias, J. M. A.This work evaluates the quality of the sediment in Ria de Aveiro, a coastal lagoon located at N of Portugal that is under strong anthropic influence, and the effects of the contamination on benthic foraminifera. The initial approach for measuring pollution was done through the load pollution index (LPI), based on As, Cd, Cr, Cu, Ni, Pb and Zn concentrations, and determined by total digestion of the sediments (T...
