Potential genesis and implications of calcium nitrate in Antarctic snow

Kanthanathan Mahalinganathan and Meloth Thamban

Data sets

Major ion chemistry and selected snow accumulation rates of snow cores along two transects in central Dronning Maud Land and Princess Elizabeth Land Mahalinganathan, K and Thamban, M https://doi.org/10.1594/PANGAEA.854383

Short summary

Our results show a strong association between calcium and nitrate ions in snow from two different regions that are > 2000 km apart in East Antarctica. Such association could have formed during the interaction between long-range transported dust with the atmospheric nitrate. This study also implies that apart from other well-known sources of nitrate in Antarctica, nitrate associated with mineral dust could form a significant portion of total nitrate deposited in Antarctic snow.
