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 meanest life, the poorest existence, is attributed to God’s will, but as human beings become more affluent, as their living standard and style begin to ascend the material scale, God descends the scale of responsibility at a commensurate speed.”
—Maya Angelou (b. 1928)
