Has sea floor been mapped?

Slowly but surely the proportion of the global ocean floor that's been properly mapped is rising.

What are 2 methods used in mapping the ocean floor?

Backscatter & Bathymetry

MBES systems have become a preferred tool for wide-scale ocean floor mapping due to the benefit of collecting both bathymetric and backscatter data simultaneously. The use of MBES observations of acoustic scattering in the water column is also on the rise in oceanographic studies.

When was the sea floor mapped?

In 1957, the publication of Heezen and Tharp's physiographic map of the North Atlantic was the first map of the seafloor that allowed the general public to begin to visualize the ocean floor.
