Rhawn Denniston, professor of geology at Cornell College, has won two grants from the National Science Foundation to further his research into ancient climate change.

The first, a four-year grant for $149,601, is to continue his research on stalagmites in an Australian cave that created a two-millennia-long climate record. The research was published in March in the Proceedings of the National Academy of Sciences. Denniston and an student from Cornell College will travel to Australia this summer to expand on his research.

The second grant, which provides funding of $21,531 for one year, will support research on fossil corals in the Dominican Republic to find evidence of El Niño–Southern Oscillation. Denniston and junior geology major Thomas Weiss will  perform research this summer at the Stable Isotope Lab at Iowa State University to help further that project.
