Lake Sediment Core

Caption

Elizabeth Thomas, UB assistant professor of geology, holds a sediment core -- a cylindrical sample of lakebed mud. Such samples contain organic matter that can be analyzed to learn about a region's past climate. The new study was based on data from a sediment core extracted from the bottom of Sikuiui Lake in western Greenland.
