The Southeastern United States is an important agricultural region, but recent flooding and drought events have caused billions of dollars in economic loss. There is a lack of understanding about what drives hydroclimate change, in part because there are fewer paleoclimate records from this region compared to the rest of the United States. This NSF sponsored project will collect sediment cores from four lakes, two in northern Georgia and Alabama and two in the south. These regions are expected to respond differently depending on what predominantly controls hydroclimate.
