*RIP
CURRENT:
"Most waves are formed
by wind and water. Sea waves usually result from storms, often hundreds of
miles from shore...When waves break, water is pushed up the slope of the shore.
Gravity pulls this water back toward the sea. If it converges into a narrow,
river-like current moving away from shore, it forms a RIP CURRENT"*.
Considering our combined high seas and winds, please take special care with your
guests, children and pets when swimming along the shore.

*Datum:
Choosing a datum for
nautical charts: For safety reasons,
a mariner must be able to know the minimum depth of water that could occur at
any point. For this reason, depths and tides on a nautical chart are measured
relative to chart datum,
which is defined to be a level below which tide rarely falls. Exactly how this
is chosen depends on the tidal regime in the area being charted and on the
policy of the hydrographic office producing the chart in question; a typical
definition is Lowest Astronomical Tide (the lowest tide predictable from based
the effects of gravity), or Mean Lower Low Water (the average lowest tide of
each day), although Mean Sea Level is sometimes used in waters with very low
tidal ranges.
Conversely, if a ship is to safely pass under a low bridge or overhead power cable, the mariner must know the minimum clearance between the masthead and the obstruction, which will occur at high tide. Consequently, bridge clearances etc are given relative to a datum based on high tide, such as Highest Astronomical Tide or Mean High Water Springs.
