Topographic Map Of The Ocean Floor: Web topographic maps show the physical shape of dry land using elevation values. Web gebco’s gridded bathymetric data sets are global terrain models for ocean and land. Web the ocean floor is almost entirely underlain by mafic oceanic crust (mostly basalt and gabbro, as described in more detail below), while the continental slopes are.
