While we take a lot of care to make these tide charts as accurate as possible, we can't guarantee the data or be held responsible for any untoward consequences arising from their use.
Please be aware that all tide charts are really just predictions and assume average weather conditions.

  Tide - LoveToKnow 1911
The average height at spring tide between high and low-water marks is called " the spring rise "; the similar height at neap tides is, however, called " the neap range." " Neap rise " is used to mean the average height between high-water of neap tides and low-water of spring tides.
The practice of the British admiralty is to refer their soundings and tide tables to " mean low-water mark of ordinary spring tides." This datum is found by taking the mean of all the available observations of spring tides, excluding, however, from the mean any spring tides which may be considered abnormal.
As a considerable part of our practical knowledge of tides is derived from observations in estuaries and rivers, we shall state the results of an investigation of waves which travel along a shallow canal, and we refer the reader to the article Waves for the mathematical investigations on which they are based.

  Tide - Wikipedia, the free encyclopedia
The tide is the cyclic rising and falling of Earth's ocean surface caused by the tidal forces of the Moon and the Sun acting on the Earth.
The changing tide produced at a given location on the Earth is the result of the changing positions of the Moon and Sun relative to the Earth coupled with the effects of the rotation of the Earth and the local bathymetry.
These depths are relative to "chart datum", which is the level of water at the lowest possible astronomical tide (tides may be lower or higher for meteorological reasons) and are therefore the minumum water depth possible during the tidal cycle.

 Tide - MSN Encarta
Tide, periodic rise and fall of all ocean waters, including those of open sea, gulfs, and bays, resulting from the gravitational attraction of the moon and the sun upon the water and upon the earth itself.
Because the force of gravity decreases with distance, the moon exerts a stronger gravitational pull on the side of the earth that is closer to it and a weaker pull on the side farther from it.
Spring and neap tides occur about 60 hours after the corresponding phases of the moon, the intervening period of time being known as the age of the tide or age of the phase inequality.

 tide. The Columbia Encyclopedia, Sixth Edition. 2001-05
More generally, tides are the deformations of celestial bodies from a perfectly spherical shape that result from stresses created by their mutual gravitational attraction (see gravitation).
The tide regarded as a wave is sometimes referred to as a tidal wave, although this term has been commonly applied to the shock wave propagated by an underwater earthquake.
Spring tide, having the maximum range, occurs during the full moon when the earth is between the moon and the sun, and new moon when the moon is between the earth and the sun.

 Tide Pools
The small tide pool, which was 9.5cm in depth, 26.7m from the shore, and 5.3m in area yielded the discovery of the fewest organisms.
The medium tide pool, which was 26cm in depth, 29.3m from the shore, and an area of 8.8m yielded the second fewest organisms.
If the crab was caught in the small tide pool, it would not have places to hide, it would have less food to eat, or it would probably die from one of the abiotic factors, such as lack of oxygen, or overheating.

The tide is the regular rising and falling of the ocean's surface caused by the Moon's gravity (and to a lesser degree the Sun's).
Instead, the tide is caused by tidal forces, which are due to the difference in gravitational attraction on the near and far sides of a body.
These "land tides" are not as pronounced as the ocean tides, however, due to the reduced flexibility of Earth's crust and mantle.

 Navis.gr - The Tides
The tides are the regular rise and fall of the ocean.
The direct tides, however, are influenced by the depth of ocean basins, by the Earth's rotation, and by the continental boundaries they touch, so the high tides do not follow the moon and the sun exactly.
It is difficult to predict astronomical tides solely from observation of the movements of the moon and the sun.

Tides are charted on a marjoram which shows the height of the tide above mean low water (sea level) and the time of the peaks of the high/low tides.
The wavelength of this wave is 1/2 the circumference of the earth and period 12 hr and 25 min.
The tide wave produced by the moon is greater magnitude and continually moves eastward relative to tide wave produced by the sun and therefore the tide forces produced by the moon are greater and more important than that of the sun (therefore tidal day 24h50m).

 Coastlines 2004-2005: Tide Pools—Depths Observable from Dry Land
Tide pools, as their name implies, are the pools of seawater that remain in the intertidal zone (i.e., the area between high and low tide) when the tide has receded.
The location of the pool in relation to low and high tides is a key physical factor, determining the amount of time a tide pool remains submerged by ocean waters or exposed to air during the daily tidal cycle.
Tide pool aficionados are keenly attuned to the lunar cycle of spring (extreme) and neap (weak) tides so they know when they can reach some low tide pools that are only accessible during spring tides.

It can be shown that the forces at the sub-lunar and antipodal points are approximately equal and that the inward forces at the sides are about half that size.
Because the Moon's tidal forces drive the oceans with a period of about 12.42 hours (half of the Moon's synodic period of rotation), which is considerably less than the natural period of the oceans, complex resonance phenomena take place.
In particular it turns out that Seleucus of Seleucia (II B.C.) used his gravitational explanation to prove it was the Earth that revolves around the Sun, not the opposite.

First of all, tide is the rise and fall of water caused by gravitational forces of the moon and sun on the oceans of the earth.
The actual height of the tide is influenced by the shape of the coastline and depth of the water.
Two other areas that need to be covered are "spring tides" and "neap tides." It was mentioned previously that the tides are affected by both the sun and the moon.

The main objective of the TIDE project is the development and validation of comprehensive dynamical models of saltmarsh and upper intertidal systems incorporating both physical and ecological processes.
The TIDE socio-economic work will investigate the implications of policy change on the perception of coastal management by the public and those that use the coast for their livelihood (farmers, fishermen etc).
The requirements linked to these goals are different and often contrasting, and an important contribution of the TIDE project is the formulation of management approaches capable of reconciling them to a satisfactory degree.

The term Paschal Tide was usually interpreted to mean the two weeks between Palm and Low Sundays (Synod of Avignon, 1337); by St. Antonine of Florence it was restricted to Easter Sunday, Monday and Tuesday by Angelo da Chiavasso it was defined as the period from Maundy Thursday to Low Sunday.
