Reconstructed volcanic stratospheric sulfur injections and volcanic sulfate deposition over Greenland and Antarctica for the Bølling-Allerød/Younger Dryas transition (13.20-12.80 ka BP).
We used four polar ice cores - two from Greenland and two from Antarctica - to investigate volcanic sulphate deposition on polar ice sheets between 13,200 and 12,800 years BP. From Greenland, we employed discrete sulphate measurements from the Greenland Ice Sheet Project Two (GISP2; 72.97°N, 38.80°W...

We used four polar ice cores - two from Greenland and two from Antarctica - to investigate volcanic sulphate deposition on polar ice sheets between 13,200 and 12,800 years BP.
