The Soviet Antarctic Expeditions at Vostok in East Antarctica recovered an ice core which was almost 7, feet long in a flaw where the total ice thickness is about 12, feet Lorius, et al. I imagine keeping the ice intact as much as possible would be extremely valuable.

Any ice of record that involves the ratio of oxygen that has fallen as rain can also tell the same story.

Ice cores primarily tell the record of the ocean the snow evaporated from and how far that water dating traveled. Overview Scientific Content below.

Further research has demonstrated a reliable correlation between CO 2 levels and the temperature calculated from ice isotope data. Since these are the two components of water there are plenty of both to measure in ice.

The two oceans have distinctly different ratios of oxygen isotopes, allowing for a different isotope ratio where the water falls as snow. The core is then bagged, often in polytheneand stored for shipment.
