The Atlas is absolutely unique. Its uniqueness and value stem from the detailed information provided on many key characteristics of Arctic sea ice never before available in such amount from any source in the public domain, even at the present time when remote sensing is still unable to record as many characteristics as humans can. The Atlas also contains a monograph, which summarizes Dr. Romanov's profound insight into dynamic processes in drifting sea ice and its morphological transformations. The data plotted in the charts include:
Dynamics of sea ice drift and formation of oceanic ice massifs ? Summary of meteorological characteristics ? Seasonal changes in Arctic sea ice, melting rates, dates of major freezing/thawing phases, water openings in ice ? Ice age/thickness distributions and probabilities, total and partial ice concentrations, ice thicknesses in Siberian shelf seas in 1982-86, ice edges and partial ice concentration boundaries in 1972-80 ? Distributions and probabilities of ice ridges and their sail width and height, sail heights and widths in shelf seas in 1983-86, keel drafts and their probabilities, area coverage, sizes of ice pieces within ridges, multi-year ice hills, belts of ice ridges, stamookhas ? Sizes and distributions of ice fields of monolithic multi-year ice, first-year ice, polynias, breccial ice fields; sizes of ice fields in shelf seas in 1983-86 ? Distributions of snow depth on level ice, ridges and multi-year ice hills, snow tongues and sastrugies ? Navigation of ships in the Arctic Ocean and adjacent seas ? Operation of aircraft in the Arctic, probability of finding landing fields for various types airplanes and the life span of runways on sea ice, statistics of flight-restricting weather. A large portion of the database used for this atlas is the only existing source of information about sea ice in the Arctic Basin and continental shelf seas collected systematically for almost six decades, from 1930's.
