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 1977, but is still relevant today. Many depths are indicated, but they are quite small so hard to read. The islands, ocean crests and continental shelves are nicely illustrated!
The most accurate depiction of the world's ocean floor is with the Marie Tharp maps.
