Isotopic and trace element geochemistry

We are interested in the spatial variability of dust deposition in the Luquillo Mountains. We are working on understanding controls on dust deposition such as topography and vegetation, the mechanisms of dust deposition including the relative importance of wet versus dry deposition, and the implication of dust as a nutrient source for Luquillo ecosystems. We are using geochemical tracers including trace element ratios, rare earth element patterns, and Sr and Nd isotopes to study soils in the Luquillo CZO.
