Open Polar Sea
Hypothesized ice-free ocean surrounding the North Pole
Open Polar Sea
The Open Polar Sea was a conjectured ice-free body of water that was believed to encircle the North Pole. Although this theory was widely accepted and served as a basis for many exploratory expeditions aimed at reaching the North Pole by sea or discovering a navigable route between Europe and the Pacific via the North Pole, it was ultimately proven to be untrue.
