Unique physical world map. Marie Tharp (with Bruce Heezen) created the first accurate map of the ocean floor, a project they started in the 1950's. This map was published in 1980, but is still relevant today. The islands, ocean crests, trenches and continental shelves are highly illustrated!
The most accurate depiction of the world's ocean floor is with the Marie Tharp maps.
Measures 38" x 27", thin glossy lamination
Only a few cities shown, no countries
Dramatic shading particularly in the oceans
Superb physical world detail: shading on land and water, mountain range names, rivers, fracture zones, seamounts, continental shelves, trenches, depths
