Ice cores contain an abundance of information about climate. 

Inclusions in the snow of each year remain in the ice, such as wind-blown dust, ash, bubbles of atmospheric gas and radioactive substances. 

Ice core datasets collected several ice cores from coastal Dronning Maud Land, East Antarctica. 

The details of the ice cores parameters : 
O2 & H2 isotopes, Major ions (Cl-, MSA, Br-,NO3-,SO42-,Na+,K+,Ca2+, Mg2+,NH4+), Dust concentration
