The North Pole. I suppose that the best way to think of the North Pole is to consider a single point on the sea bed under the Arctic Ocean where all the Earth's lines of longitude converge. It is the one point in the Northern Hemisphere around which our planet turns, and its position now is marked by a titanium flag that was recently placed on the ocean floor by the Russian Federation.
Above the North Pole and that Russian flag we have 4261 meters of salt water and a layer of sea ice that varies in thickness from 1 to 3 meters depending on the time of year and the temperatures of the air above it and the water beneath it.
The Arctic ice cap moves relative to the sea floor. The moving ice provides no permanent foundation for a research station of even a camera or a flag. The ice that was on the ocean’s surface above the North Pole when I was there on July 25, 2008 has since moved on to somewhere south. Indeed, this ice had shifted several miles before we left the vicinity of the North Pole later in the day on the 25 of July.
Early polar explorers had a difficult time reaching the North Pole in part because of the moving target. The ice could move faster than they could move. Expeditions lasted years as they wandered on the shifting pack ice. The location of the Pole had to be calculated using the height of the sun, and it had to confirmed mathematically many times as the explorers approached 90 degrees North. When explorers stopped for their calculations, the ice still moved them along so that their calculated position would no longer be correct.
Our journey took only a few days, and confirmation of our arrival at the North Pole required no sextant or calculator. We arrived at the Pole on an ice breaker, and our position at 90 degrees North Latitude was confirmed by GPS.
There is a prediction that global warming will melt the north polar ice during this century. There was even a suggestion that the Pole might thaw this summer, which was not true at the end of July.
