How far north can we meet polar bears – and how far south?
No reports have put polar bears exactly on the North Pole itself, but ca. 100 miles to the south, at 88°N. Thus, there is no doubt that there are polar bears in the vicinity of the North Pole, though they are probably not abundant because the ocean there is less biologically productive than it is over the continental shelf, at the edges of the polar basin and associated islands. There is little detailed knowledge about polar bear migrations in the Polar Basin, since there has been little research carried on there. The Arctic Ocean basin is among the earth’s most remote areas, and the logistics and cost of such studies are limiting factors. However, there are numerous reports from polar explorers and expeditions that have encountered occasional polar bears in the permanent ice cap around the North Pole. The furthest south that polar bears live on a year-round basis are in James Bay in Canada, where bears den at about 53°N on Akimiski Island. On a seasonal basis some bears appear regular
