Neap tide:
A daily tidal range of minimal amplitude that occurs when the moon and sun are positioned at 90 degrees to one another. In this moon-earth-sun configuration, the gravitational attraction of the moon and sun compete for Earth's water.

specific tide levels, which are used as surfaces of reference for depth measurements in the sea and as a base for the determination of elevation on land. Many different datums have been used, particularly for leveling operations

The Black Tide condition was bad in late 2004 extending into 2005, Both SeaWiFS and MODIS were effective in monitoring this situation: ...
For stations with shorter series, simultaneous observations are made with a primary control tide station to derive the equivalent of a 19-year value. Use of "mean high tide" is discouraged.
IF salt marsh elevation is greater than or equal to spring tide level THEN the marine sedimentation rate equals zero. In such an example the resulting state is assumed to hold for all locations where the initial state is true.
(b) located on state lands seaward of the mean high tide line of the Gulf of Mexico in water of a depth at mean tide of not more than 100 feet that is sheltered from the direct action of the open seas of the Gulf of Mexico.
The intertidal wetlands must be able to survive extreme conditions of mainly salt water at high tide, fresh water at low tide and times of flood and brackish water at other times.
Begin with our view zoomed out but more or less focused on the bottom of the stairs on our tide-ledge.
Make sure that our people layer is the current layer.
The shoreline of tidal waters will be mapped to represent the mean high water line (mean high tide level) ...

Bathymetric heights, for example, the water depths shown on hydrographic charts, are usually based upon Lowest Astronomical Tide (LAT). This makes sense as mariners need to know the least possible depth.
In order to establish the geoid as reference for height measurements, the ocean's water level is registered at coastal places over several years using tide gauges (mareographs).
Caesar waited until mid-afternoon for the ships to assemble near the cliffs and then, with both wind and tide in his favor, sailed to a more suitable landing point on a nearby open beach. But on what date did Caesar invade Britain?
Mean Sea Level
The average level of the ocean's surface, as measured by the level halfway between mean high and low tide. Used as a standard in determining land elevation or sea depths.
(high tide or low) become pertinent questions. So, to avoid these problems, a reference datum is needed that represents the same surface or elevation at all points on the earth and that remains constant over time.
Over the past one hundred years, a national network of vertical control points or "benchmarks" has been created by levelling along major roads and railways in Canada and by linking more than 30 tide gauges operated by the Fisheries and Oceans Canada.
only if impacted by the indicated surge, which on the open coast typically occurs to the south of the eye at landfall and will decrease with distance along the coast from the eye wall. These estimates assume landfall occurs at mean astronomical tide ...
