How were ice cores outdated? Dating the ice gets difficult with range.
I found myself thinking exactly how ice cores include dated precisely. I’m sure Carbon 14 is certainly one strategy, however some ice cores go back thousands of years. Would more isotopes with longer half-lives be much more precise?
Also, exactly how much will it cost as of yet the core? Exactly how tend to be examples obtained without damaging the ice? We imagine keeping the ice undamaged as much as possible would be extremely valuable.
