The geologic record holds information that is used to explore climate relationships in the geologic past and to understand present and future projections. Climate models rely on accurate and abundant proxy data in order to constrain physical relationships and refine climate model assumptions.
I'm currently developing a dataset of climate proxies throughout the Midwest. A wind-blown dust (loess) has served to preserve terrestrial snails which capture carbon and oxygen isotopes into their aragonite shell. By combining geologic indicators with the spatially and temporally abundant snail record, I aim to create an ISOMAP of regional and temporal climate changes with a focus on the Last Glacial Maximum.
I am advised by Professor Jessica Conroy, Professor William Guenthner and Dr. David Grimley of the Illinois State Geologic Survey.
