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.
