Analysis of the physical and chemical properties of an ice core can reveal past variations in climate ranging from seasons to hundreds of thousands of years.
Ice core records can be used to reconstruct temperature, atmospheric circulation strength, precipitation, ocean volume, atmospheric dust, volcanic eruptions, solar variability, marine biological productivity, sea ice and desert extent, and forest fires.
) can be used to identify input from volcanic sources.
The 1815 Tambora Eruption, responsible for the “year without a summer”, is a commonly used “dating horizon” that has been found in ice cores around the Earth.
The approximate time since the organism died can be worked out by measuring the amount of carbon-14 left in its remains compared to the amount in living organisms.
Pripyat is the central location where the Chernobyl Nuclear Power Plant accident occured in the Ukrainian Soviet Socialist Republic back in 1986.
Krypton is a noble gas which can get locked up in air bubbles of ice and stay there as more and more layers of snow (which eventually compacts into ice) are piled on top of it over time.Theoretically, this method could be used to date ice that is 1.5 million years old.
