Multiple Entries   This block may be repeated several times, just increase the number "x"        
Height difference   Please provide the difference "GNNS-Marker" Minus "TGBM"       Please note, the difference "Marker->ARP" is given in the respective IGS GPS site log !
Fact Sheet available Please indicate, whether a Fact Sheet (register) is available on request. Some Hydrographic Agencies have a register (in german: Pegelstammbuch") available which gives a very detailed description of the history of the tide gauge (with auxiliary information like reconstruction work, harbor accidents, and so on).
Tide Gauge Reading Please provide the actual tidal height (in respect to the "Datum of Observations) in [m] The tidal height should be given for the "Survey date" time
