A large, color relief map of Earth, showing features both above and below sea level. A prominent ridge runs along the ocean floor. It starts near Greenland, winds down between South America and Africa, curves into the Indian Ocean, then doubles back along itself to pass below Australia and into the Pacific. It appears to end near Baja California.

Here is the World Ocean Floor Panorama that Tharp and Heezen produced in 1977. Only one printer in the US could handle such a large job. It was painted by Heinrich Berann, who was famous for his landscapes.
