Status	Attribute label	Enumerant label	Concept definition	Code	Ref type	Reference ▾
STD 2005/06/07	SOUNDING_DATUM_TYPE	MEAN_WATER_LEVEL	The mean of all hourly water levels over the available period of record; mean water level.	38	PR	[S57A, Attribute, VERDAT:26]
STD 2005/06/07	SOUNDING_DATUM_TYPE	LOWER_LOW_LARGE_TIDE	The mean of the <<<LOWEST_LOW_WATER>>>s, one from each of 19 years of observations; lower low water large tide.	21	PR	[S57A, Attribute, VERDAT:27]
STD 2005/06/07	SOUNDING_DATUM_TYPE	HGHR_HIGH_LARGE_TIDE	The mean of the <<<HIGHEST_HIGH_WATER>>>s, one from each of 19 years of observations; higher high water large tide.	8	PR	[S57A, Attribute, VERDAT:28]
STD 2005/06/07	SOUNDING_DATUM_TYPE	NEARLY_HIGHEST_HIGH	An arbitrary level approximating the highest water level observed at a <LOCATION>, usually equivalent to the <<<HIGH_WATER_SPRINGS>>>; nearly highest high water.	41	PR	[S57A, Attribute, VERDAT:29]
STD 2005/06/07	SOUNDING_DATUM_TYPE	MEAN_LOWER_LOW_SPRINGS	The mean height of <<<LOWER_LOW_WATER>>> at <SPRING_TIDE>s at a <LOCATION>; mean lower low water springs.	34	PR	[S57A, Attribute, VERDAT:2]
STD 2005/06/07	SOUNDING_DATUM_TYPE	HIGHEST_ASTRONOMICAL- _TIDE	The highest <<TIDE_LEVEL>> that can be predicted to occur under average meteorological conditions and under any combination of astronomical conditions; highest astronomical tide.	12	PR	[S57A, Attribute, VERDAT:30]
STD 2005/06/07	SOUNDING_DATUM_TYPE	MEAN_SEA_LEVEL	The mean height of the <WATERBODY_SURFACE> of the <OCEAN> at a <TIDE_DATA_POINT> for all stages of the <TIDE> over a 19-year period; mean sea level (MSL). MSL is usually determined from hourly height readings measured from a fixed predetermined reference level.	36	PR	[S57A, Attribute, VERDAT:3]
STD 2005/06/07	SOUNDING_DATUM_TYPE	LOWEST_LOW_WATER	An arbitrary level conforming to the lowest <TIDE> observed at a <LOCATION>, or somewhat lower; lowest low water.	25	PR	[S57A, Attribute, VERDAT:4]
STD 2005/06/07	SOUNDING_DATUM_TYPE	MEAN_LOW_WATER	The mean height of all the lowest <<TIDE_LEVEL>>s at a <LOCATION> over a 19-year period; mean low water.	33	PR	[S57A, Attribute, VERDAT:5]
STD 2005/06/07	SOUNDING_DATUM_TYPE	LOWEST_LOW_SPRINGS	An arbitrary level conforming to the lowest water level observed at a <LOCATION> at <SPRING_TIDE>s during a period shorter than 19 years; lowest low water springs.	24	PR	[S57A, Attribute, VERDAT:6]

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
