| Summary: | Shows five types of ice: permanent polar pack, unnavigable sea and land-fast ice, icebreaker penetrable, navigable by heavily built vessels, and navigable by unreinforced vessels. Shows extent of ice by average extent, extremes, vicinity of icebergs and/or growlers, and exceptional positions. Scales shown by direction (north-south, east-west, and diagonal) for various latitudes. Atlas provides colored monthly maps detailing the extent and character of the ice for each principal region of the Northern Hemisphere known to have seasonal or permanent sea or lake ice. Also includes statistical tables. |
