The Environmental Change Laboratory in the Department of Geosciences at FAU studies human-environment interaction and environmental change across the Holocene. The lab uses fieldwork and laboratory methods to reconstruct environmental and climate histories that serve to inform the present. The lab also has projects that model future and past environments.
Fieldwork is primarily focused in the Neotropics with projects investigating pre- and post-maize agricultural fire histories, the timing and pathways of key agricultural domesticates, societal response to multi-decadal drought events, the development of paleoclimate records, reconstructions of past landscapes, and the impact and modeling of paleo flooding and sea level change. Research project locations include Costa Rica, Ecuador, Nicaragua, the Dominican Republic, and Florida.
The lab's research utilizes a multi proxy approach to reconstructing environmental change. Methods employed include: pollen analysis, microscopic and macroscopic charcoal analysis, isotope geochemistry, organic matter analysis, elemental analysis (XRF), Bayesian age-depth modeling, and GIS modeling. The lab is equipped to collect and analyze sediment cores from lake and wetland locations.
