The role of ocean dynamics in the Arctic water contamination

Using a rough resolution model of the ice-ocean interaction and seasonal atmosphere climate data, the main feature of the Arctic ocean circulation and ice drift were reproduced. On the basis of the restored dynamics the transport of contaminated materials from the Yenisey river mouth in the Kara Sea was investigated. Two general pathways were finally found: the first one is a passage through the Denmark Strait into the North Atlantic circulation system, and the other is the involvement into the Canadian anticyclonic gyre with a long-living ice as a core.
