As the ice must be melted for analysis, the sample is usually destroyed during analysis. Consistent dating for Antarctic and Greenland ice cores.
Ice cores are expensive to collect, house and keep.They must be stored continuously at a specific temperature.I was wondering how ice cores are dated accurately.I know Carbon 14 is one method, but some ice cores go back hundreds of thousands of years.
The American National Ice Core Laboratory provides some information on how they store and keep ice cores. A synchronized dating of three Greenland ice cores throughout the Holocene.
When ice cores are analysed, they may be cut or sectioned, with half the sample remaining as an archive. Recent Antarctic Peninsula warming relative to Holocene climate and ice-shelf history.
