Yet here, it seems they have a different understanding:
"Just as earlier researchers asked whether a climate record was stored in modern ice sheets of Antarctica and Greenland, we now ask whether ancient, debris-covered glaciers in the Dry Valleys hold similar records of temperature and atmospheric change, but on timescales that are perhaps an order of magnitude greater than that for the deepest existing ice core.
We are currently evaluating the age, origin, and climatic significance of buried ice in the western Dry Valleys region. Our group and others have published evidence that the ice is over a million years in age, making it by far the oldest ice yet known on this planet. An alternative view is that the buried ice is more recent segregation ice from the in-situ freezing of groundwater. Distinguishing between these hypotheses is key to understanding Neogene climate change of Antarctica. "
