Revolutionary mapping Sub-Oceanic Topography.
An impressive, large-format 1975 physiographic map of the Earth drawn by William Chesser. Although crude by comparison, Chesser's map is based on the revolutionary mapping of sub-oceanic topography by Marie Tharp and Bruce C. Heezen (credited in title), but predated the 1977 official cartographic release of their work. (more details)
