Table D. Components (features_F) processed within usSEABED
Only the descriptive terms found in source reports are defined in the dbSEABED thesaurus. Conversely, as usSEABED uses the same thesaurus as its sister data compilations (auSEABED, goSEABED), some terms listed below may not occur within U.S. waters. Only one of possible variations are listed below, for example, laminated (laminae, lamination); mollusc (mollusk, mollusca), etc.
