An aerial view of Canada's Mackenzie River Delta, where marine geochemists Tim Eglinton, Daniel Montluçon, and geologist Liviu Giosan are looking for clues to past climate change. During 2009 Spring field work, the team retrieved sediment cores from 22 deltaic lakes to study possible changes in sedimentation patterns that could be due to a melting of the permafrost in the high Arctic.
