Studies on climatic and environmental changes during the last few hundred years using ice cores from various sites in Nordaustlandet, Svalbard (scientific paper)
Ice coring and snow cover observations have been carried out at 3 sites in Nordaustlandet, Svalbard since 1995. The results of stratigraphic analyses, and chemical and δ^<18>O analyses from Vestfonna and Austfonna cores are presented here. The results from these sites show that most of the che...

Ice coring and snow cover observations have been carried out at 3 sites in Nordaustlandet, Svalbard since 1995.

Anthropogenic increases in trace metals, sulfate and nitrate since about 1950 are detected.
