Sea floor depth. This latest incarnation though offers in a single glance perhaps the most complete unified view of the earth s seafloor to date showing not just the mountains beneath the water but also. The acronym mbsf meaning meters below the seafloor is a common convention used for depths below the seafloor. Currently we have only mapped about 10 percent of the earth s seafloor in high resolution meaning that estimates of average ocean depth remain just that. The seafloor dips fairly steeply near the coasts but is generally flat and remarkably shallow especially in relation to nearby land elevations.
But despite their name these plains are not uniformly flat. Sunlight does not penetrate to the sea floor making these deep dark ecosystems less productive than those along the continental shelf. Depth below seafloor is a vertical coordinate used in geology paleontology oceanography and petrology see ocean drilling.
