Geochemical atlas of Norway. Part 2: Geochemical atlas of Spitsbergen
In the1980's there was great interest in prospecting for oil, gas and minerals in Spitsbergen. Norsk Hydro and Store Norske Spitsbergen Kullkompani contacted the Geological Survey of Norway in 1986 and asked for help to map the island geochemically. Overbank sediment samples had just been mapped in Norway, and it was agreed upon using the same sample media in Spitsbergen.
A dense network of rivers and sreams drains Spitsbergen. Erosion and sediment transport takes place during the intense snowmelting period in the summer. NGU and the Norwegian Energy and Water Resources Dirctorate (NVE) conducted a regional mapping in 1986-87. A total of 650 samples covered the ics-free part of the island. In the samples the content of 48 elements was determined. The regional dataset i present in this atlas.
During 2007-2010, NGU, the Climate and Pollution Agency (Klif) and the Governor of Svalbard (SMS) conducted investigations on lacal sources of PCB in the Norwegian, Russian and Polish settlements og Svalbard. Some 1019 samples of paint, soil and sediments were collected and analyzed. The standing building mass was documented as an important local source for PCB to the surrounding surface soils. Parts of these data are presented as excamples ogf human impact in the Arctic
