Use of Snow and Firn Analysis to Reconstruct Past Atmospheric Composition -Discussion
Polar ice cores (and cores from certain high-altitude lower latitude sites) have proved to be a rich resource of information on past atmospheres and climate. The ideal environmental archive would faithfully record the composition of the atmosphere with no post-depositional changes. Of course, the picture is not this simple even for polar ice, but it is worth recalling a few of the many successes of ice coring.
