It's fascinating that they were able to get 9000 years of data from a mere 50 meters of ice!

- gumby 8y agoCompletely agree, but don't forget the ice is subject to significant compression due to the weight of ice/snow above it. So the layers aren't of uniform depth; at the lower end of the core they must be amazingly thin. While the last 50 years could collectively take up (perhaps) the top couple of meters.
