This Thursday Brooke Moore presented the results from her honors research at the 2015 Joint Science Presentations. Brooke used X-ray diffraction (XRD) to quantify the relative abundance of quartz and calcite minerals in a sediment core from Otsego Lake, NY. The watershed of Otsego lake consists mostly of highly magnetic shale, and increased erosion should lead to increased quartz concentrations in the watershed. Brooke’s thesis attempts to identify periods of higher than normal erosion and link erosion patterns to changes in climate through the Holocene.
For more details on Brooke’s thesis you will have to come to her senior thesis presentation on April 22nd.
