STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY RISE A broad elevation that rises gently and generally smoothly from the <WATERBODY_FLOOR> forming a <<<RIDGE>>>; rise. 41 IR [S57A, Attribute, CATSEA:43]  
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY SADDLE A broad pass, resembling in shape a riding saddle, in a <<<RIDGE>>> or between contiguous <<<SEAMOUNT>>>s. 42 PR [S57A, Attribute, CATSEA:23]  
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY SEAMOUNT <SEAMOUNT>. 44      
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY SEAMOUNT_CHAIN A <NON_EMPTY_SET> of <<<SEAMOUNT>>>s in linear or arcuate alignment; seamount chain. 45 PR [S57A, Attribute, CATSEA:45]  
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY SEA_CHANNEL A continuously sloping <TERRAIN_CHANNEL> commonly found in <<<FAN>>>s or <<<ABYSSAL_PLAIN>>>s and customarily bordered by <<<LEVEE>>>s on one or both sides; sea channel. 43 PR [S57A, Attribute, CATSEA:44]  
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY SHELF A <WATERBODY_FLOOR_REGION> adjacent to a continent (or around an <ISLAND>) and extending from the <LOW_WATER_LINE> to a depth at which there is usually a marked increase of downward slope; shelf. 46 PR [S57A, Attribute, CATSEA:21]  
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY SHELF_EDGE A narrow <REGION> at the seaward margin of a <<<SHELF>>> along which is a marked increase of slope; shelf edge. 47 PR [S57A, Attribute, CATSEA:46]  
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY SHOAL <SHOAL>. 48      
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY SILL A <WATERBODY_FLOOR_REGION> of relatively shallow depth restricting the movement of <WATER> between <<<BASIN>>>s; sill. 49 PR [S57A, Attribute, CATSEA:47]  
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY SLOPE The slope seaward from the <<<SHELF_EDGE>>> to the upper edge of a <<<CNTNTL_RISE>>> or where there is a general reduction in slope. 50 PR [S57A, Attribute, CATSEA:48]  
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY SPUR A subordinate elevation, <<<RIDGE>>>, or <<<RISE>>> projecting outward from a larger <WATERBODY_FLOOR_TOPOGRAPHIC_CONFIGURATION>; spur. 51 PR [S57A, Attribute, CATSEA:20]  
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY TERRACE A relatively flat horizontal or gently inclined <WATERBODY_FLOOR_REGION>, sometimes long and narrow, which is bounded by a steeper ascending slope on one side and by a steeper descending slope on the opposite side; terrace. 52 PR [S57A, Attribute, CATSEA:49]  
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY TRENCH <WATERBODY_FLOOR_TRENCH>. 53     [S57A, Attribute, CATSEA:6]
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY TROUGH A long <TERRAIN_DEPRESSION>, characteristically flat bottomed and steep-sided and normally shallower than a <<<TRENCH>>>; trough. 54 PR [S57A, Attribute, CATSEA:22]  
STD
2005/06/07		 WATERBODY_FLOOR_MORPHOLOGY VALLEY A relatively shallow, wide <TERRAIN_DEPRESSION>, the <WATERBODY_FLOOR> of which usually has a continuous gradient; valley. This term is generally not used for <WATERBODY_FLOOR_TOPOGRAPHIC_CONFIGURATION>s that have characteristics of <<<CANYON>>>s for a significant portion of their extent. 55 PR [S57A, Attribute, CATSEA:50]  
Group membership:

In addition to the status and date information for each entry, a colour coding scheme highlights the database holding to which an entry belongs. The following highlight colours are used:

  • white - the entry is in the standard
  • yellow - the entry has been added to the register
  • pink - the entry has been submitted for inclusion in the register, but it is not approved
  • cyan - a deprecated entry that was originally either in the standard or was added to the register, but has since been deprecated

The following icons are used to identify items that have figures, modifications and/or clarification notes:

  • F n - has Figures and, if more than one figure, n figures
  • M - has Modifications
  • C - has Clarifications
