The massive map combines the genuine scientific work of interpreting and compiling thousands of sonar images with accomplished artistry.
This work represents the culmination of over 30 years of collaboration between Tharp and Heezen, led by Tharp, to produce a meticulous sonar map of the ocean's floors.
Among other accomplishments, their work led to the discovery of the Mid-Atlantic Rift, the Mid-Atlantic Ridge (as depicted here), and redefined both submarine geology and our understanding of plate tectonics.
Moreover, Tharp's work was pioneering in elevating the role of women in the sciences.
The map offers a striking axonometric view of the terrain throughout, with a focus on the seabed. Coverage extends from the Great Lakes to France and from the St. Lawrence River and Newfoundland to the Greater Antilles and the Cape Verde Islands.

The spine-like Mid-Atlantic Ridge is prominent. Most of the subterranean peaks and valleys are labeled with a numerical system running into the thousands - likely references in a supplementary work not included here.
