Hi! I'm Annie, and my research is focused on chemical weathering in Iceland. Chemical weathering is the chemical breakdown of rocks, and the weathering of silicate rocks is considered a major component of the carbon cycle because the reaction sequesters atmospheric CO2 and thus controls global climate over geologic timescales. The weathering of basaltic rock in particular has been implicated as having a disproportionately large role in the geologic sequestration of CO2. I am investigating this in Iceland, a basaltic island on the Atlantic Mid Ocean Ridge. Through the lenses of aqueous geochemistry, radiogenic Sr, stable Sr, and stable Ca isotope geochemistry, I hope to understand both silicate and carbonate chemical weathering in Iceland.
