| Paleo Slide Set: Polar Ice Cores |
| Extruding a core | |
| Scientists extrude the core from its barrel with the utmost care. Any butyl acetate on the core surface is carefully cleaned off before sawing the ice into 2 m sections. The cloudy layers
clearly visible in this 6 m core section were formed when dust fell onto the ice sheet and was entrained in the ice. Photo Credits: Mark Twickler University of New Hampshire | Download a zip file
