Water sky is
a phenomenon that is closely related to ice blink. It forms in regions with
large areas of ice and low lying clouds and so is limited mostly to the extreme
northern and southern sections of earth, in Antarctica and in the Arctic. The
dark clouds over open water have long been used by polar explorers and
scientists to navigate in sea ice. For example, Arctic explorer Fridtjof Nansen
and his assistant Hjalmar Johansen. Source
