Abstract : Over 700 NEL sea floor photographs, obtained intermittently over a 10-year period, in a wide variety of environments, have been analyzed. Five major types of bottom microrelief, on the basis of origin, have been defined; a numerical scale of microroughness has been developed and ratings predicted for normal bottom environments; and zones of isoroughness have been delineated for large portions of the Pacific and adjacent ocean areas.
