However, although the sea ice is shrinking -- covering less total area as well as becoming thinner -- the Arctic is still a world ruled by ice, a lesson well learned when the Polar Pioneer encountered heavy pack ice between Svalbard and the eastern coast of Greenland, forcing the captain to divert the boat and drop speed to just a few knots.
