• Tide height is indicated by a gauge. The gauge is comprised
of 8 levels, which are set according to the absolute minimum /
maximum values of that particular day.
• The color of the arrow on the tide gauges indicates changes
in the tide height:
– Red : increasing tide height.
– Blue : decreasing tide height.
The animation can be viewed continuously or incrementally at a
time interval that you specify. You can also set the date for the
animation, and start or restart the animation at any point within
a 24-hour period. If the system does not have a valid date and
