Recent observations of sea level change are consistent with global warming. It has been shown that since 1993 the sea level rises at a mean rate of 3.1 mm y-1. Because the increase is not uniform globally, it is important to have reliable information on this change to corroborate the predictions of climate projections locally. In Mexico, there is a scarcity of information and availability of long-term instrumental (tidal-gauge) records. Therefore, this study proposes to determine the rates of sea level rise during the last 100 yr by the study of sedimentary records of two coastal lagoons in Veracruz, Gulf of Mexico using the 210Pb sediment dating method. This isbased on the hypothesis that accretion rates in coastal environments such mangrove saltmarshes are similar to the change insea level. Elemental composition will be used to corroborate the landward marine incursion in these ecosystems. In this work we will present the preliminary results of mangrove saltmarsh accretion in Veracruz and will compare these with instrumental records (tidal gauge and altimetry).
