I've found a nice website regarding sea ice circulation in the North. The website shows the major patterns of Arctic circulation. What I wanted to know was how fast does this current move and apparently the answer is that sea ice caught in the Beaufort Gyre will be caught up in the north for several years. I wanted to know how fast pollution reaches the arctic and found that there is one main entry point to the Arctic Ocean and that is through the Northeast Atlantic area.
However I wasn't able to find how quickly pollutants travel from America to the Arctic via ocean currents. Anyone have any information on this?
