Forty specimens, with known concentrations of copper, iron, and zinc, were used in this study. The variations recorded in Cariaco Basin sediments coincide with events in societal evolution that have been suggested previously to be motivated by environmental change. From them a first approximation of the effect of internal migration within states was obtained.

In addition, a series of observations satellite altimetry and in situ temperature, salinity and velocity datawill be used to assess the influence of the Caribbean circulation on the basin.
