An apron is an undersea topographic feature which, according to International Hydrographic Organization (IHO), is “a gently dipping seabed surface, underlain primarily by sediment, at the base of any steeper slope”. There are numerous occurrences of subsea aprons throughout the seas of the world, and occurring at various depths ranging from the Epipelagic zone to the Abyssal zone and even deeper.
Example Occurrences
An example of the occurrence of a well defined apron is the circumferential seabed landform surrounding Johnston Atoll west of Hawaii in the northern Pacific Ocean. Not only is there a well defined seabed soil apron, but there is an overlying natural rock debris apron consisting of mass wasting or erosion of the associated submarine volcano flanks.
Alternative Marine Meaning
The term apron is often used for a linkspan or connecting drawbridge from a pier or ramp to connect vehicular traffic to docked marine vessels.
