Scientists Obtaining Peat Core in Alaskan Bog
Detailed Description
USGS scientists Miriam Jones and Kristen Manies working to obtain one of the peat cores they used to determine carbon content, age, and variations in plant remains with depth. They are standing in a bog created when permafrost thawed. A treed area that still has permafrost can be seen in the background, with dying trees representing an area of active thaw.
