3 Lakes of the World Through Space and Time: Archives of Climate, Paleoenvironments, Ecosystems, Geohazards, and Economic Resources

This session celebrates lacustrine research across the globe. Lake sediments are excellent archives of changing climate, paleoenvironments, human impacts, and economic resources. This session explores limnogeological research on all time and spatial scales.
