Microscale Distribution of Impurities in SnOw and Glacier Ice (MiSo)
Project Overview"The impact of the physical micro-environment of impurities in snow on their re-distribution during metamorphism, on the chemical reactivity, and the transfer to ice core archives."
However, it still remains unclear how chemical impurities are embedded in snow. In particular, the snow cover on earth is not static but large structural changes side-by-side with substantial redistribution of ice mass even on small temporal and special scales occur during metamorphism.4 To which extent impurities are redistributed during snow metamorphism and how this influences their chemical reactivity and their preservation in ice cores is currently unknown. This is fundamental to snow chemistry, atmospheric science and to the integrity of ice cores as climate and environmental archives.
