7. Possibilities Warm +2 degrees, Cool -2 degrees
During warming, mudstone with clasts 500 years, diatomite 500 years
During cooling, diatomite 2900 years, mudstone 3100 years, diamictite 3000 years
Core Story: Thousands of years ago, the earth underwent a warming phase with diatoms thriving in the Antarctic waters. Then a cooling phase led to the depositing of mudstone. The earth warmed again, creating diatomite. Then the earth underwent a long ice age, cooling the earth and depositing many rocks from glaciers as clasts. Finally the earth warmed again, creating diatomite.
Diatomite is longest trend, because it occurs the slowest.
Drill Site #2 receives longer impact from the glacier movements and less time exposed to open water.
Radio carbon dating, fossils, could be used for the cores, for dating purposes. Somehow we would need to tie to core to known events with dates meters = 1 million years?

10. Summary
Antarctica and the Earth as a whole have experienced climate change for millions of years
Right now we are in a relatively cold time or icehouse
Antarctica was once very warm
Scientists use cores from Antarctica to understand climate change
