Dating antarctic ice cores who is massari dating

We are hereby presenting a new dating method based on inverse techniques, which aims at calculating consistent gas and ice chronologies for several ice cores.

The proposed method yields new dating scenarios simultaneously for several cores by making a compromise between the chronological information brought by glaciological modeling (i.e., ice flow model, firn densification model, accumulation rate model), and by gas and ice stratigraphic constraints.

While I didn't count 4,000 layers, I could see several hundred.

In my view it just isn't reasonable to claim that all of that ice was laid down in just a few years after the flood.

Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper, and an ice core contains ice formed over a range of years.

I understand that the age of the ice at Camp Century (very near to where I was) is over 100,000 y.

Figure 1 Scientists measure ice cores from deep drilling sites on the ice sheet near Casey station Photo by M. The annual precipitation of snow, averaged across the continent, is about 30 centimetres, which is equivalent to about 10 centimetres of water.

Holmes, 1993 © Copyright Australian Antarctic Division Antarctica is the coldest, windiest, highest and driest continent on Earth. In some locations as little as 2 centimetres (water equivalent) is recorded.

Some volcanic events which were sufficiently powerful to have distributed material around the globe leave a signature in the ice which can be detected in many different cores, allowing synchronization of the time scales between two different locations.

Beneath the Antarctic ice is a world unlike any other.

The ice at Camp Century isn't even half the thickness at the center of the cap.
