The Zhubov scale is a way of reporting polar sea ice coverage, it was developed in the former USSR by Russian naval officer N. N. Zhubov (1895 - 1960).
The Zhubov scale is measured using the unit ball, one ball equals 10% coverage, five balls 50% coverage and so on.
Famous quotes containing the word scale:
“The Humanity of men and women is inversely proportional to their Numbers. A Crowd is no more human than an Avalanche or a Whirlwind. A rabble of men and women stands lower in the scale of moral and intellectual being than a herd of Swine or of Jackals.”
—Aldous Huxley (18941963)
