An example of the Aveiro estuary (Portugal) A1 Daza, Mª. J. A1 Quintana, Benito A1 Barba, Pedro A1 Bernardes, C. A. A1 Corrochano, A. AB In this work, we show the preliminary results on the 137Cs dating of the tidal flood sediments in the barrier-island system of Aveiro (Portugal). The ”7Cs activity enable us to establish four isochrones which limit the last four decades, through the correlation of historical data of137Cs atmospheric concentration. The sediment acumulation rates on the intertidal flat is calculated to be 0.6 cm yr1 PB Sociedad Geológica de España YR 1997 FD 1997 LK http://hdl.handle.net/10272/10338 UL http://hdl.handle.net/10272/10338 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
