During a flood tide, when the water level is rising between low and high tides, the tidal current flows toward shore. During an ebb tide, when the water level is falling between high and low tides, the tidal current moves away from shore (Fig. 6.18). The greatest tidal currents occur midway between high and low tide. A <strong>slack tide</strong> is when there is no current. In most areas of the world, slack tides occur near high and low tide when the flow of water is changing direction.</p> <p> </p> <p>In addition to moving water toward and away from shore, tidal currents often cause a parallel flow of water along the shoreline. For example, in waters off Honolulu, Hawai‘i, the rising tide tends to cause coastal currents to flow west, and falling tides tend to cause coastal currents to flow east.</p> <p> </p> <p>Tidal currents are usually the strongest currents in coastal regions. Experienced coastal sailors know that they must be prepared for both tides and tidal currents when navigating sailboats and other crafts into and out of coastal inlets. They must make sure that hulls of their crafts do not run aground during low tide and that they have enough power to advance against strong tidal currents.</p> <p> </p> <p> </p> <p> <!-- THEME DEBUG

requires knowledge of the time and height of the tides, as well as the speed and direction of the water as the tides move in and out. This information is critical to sailing ships because they have to take advantage of the tides and currents to maneuver correctly. The captains of large transport ships also need to be aware of the tides because navigating a large ship through shallow, narrow channels leaves little room for error.</p> <p> </p> <p>Because the movements of the earth, moon, and sun are predictable, tide characteristics such as tide height, zero point, and mean lower low-water level are predictable. <strong>Tide height</strong> is usually measured from the low-water mark, which is considered the <strong>zero point</strong>. This procedure is simple in areas where the tide is relatively constant. However, in areas where tides are continually changing, scientists use an average (mean) of the low tide levels. This average is called the <strong>mean lower low-water level</strong> (<strong>MLLW</strong>). All tide heights at a location are measured from the zero point. When the low-water level is lower than the zero point, tide height is measured with a negative number and is called a <strong>minus tide</strong>.</p> <p> </p> <p><strong>Tide tables</strong> are based on average tidal data obtained at a given location for many years. An example is shown in Table 6.2. Tide table data can be plotted to make <strong>tide graphs</strong>.</p> <p> </p> <table border="1" cellpadding="1" cellspacing="1" style="width: 650px;"><caption><strong>Table 6.2.</strong> Tide

the strongest influence on the tides—followed by the gravitational force of the sun—other factors also influence tides. One of these factors is the angle of the moon’s orbit with respect to the earth-sun orbital plane. The moon’s orbital path around the earth is not in line with the equator. Instead, the moon’s orbit is tilted or angled from the equator (Fig. 6.10). As the moon completes its orbit around the earth, it is north of the equator for half of the lunar month and south of the equator for half of the lunar month. The moon is only directly above the earth’s equator for two days in the lunar month. The moon's angular distance north or south of the equator is called its <strong>declination</strong>. The moon’s declination changes throughout the month as the moon moves in its orbit around the earth.</p> <p> </p> <p>The two tidal bulges track the changes in lunar declination. When the moon is north of the equator, the maximum lunar tidal bulge on the near side of the Earth is also north of the equator (Fig. 6.10 A). The locations of these bulges cause daily changes in the tide.</p> <p> </p> <p> </p> <!-- THEME DEBUG --> <!-- THEME HOOK: 'media' --> <!-- FILE NAME SUGGESTIONS: * media--source-image.html.twig * media--image--colorbox-small.html.twig * media--image.html.twig * media--colorbox-small.html.twig x media.html.twig --> <!-- BEGIN OUTPUT from 'themes/tsi/templates/media.html.twig' --> <article class="align-left media media--type-image media--view-mode-colorbox-small"><!-- THEME DEBUG --><!-- THEME HOOK: 'field' --><!-- FILE NAME SUGGESTIONS: * field--media--field-media-image--image.html.twig * field--media--field-media-image.html.twig * field--media--image.html.twig * field--field-media-image.html.twig * field--image.html.twig x field.html.twig --><!-- BEGIN OUTPUT from 'themes/tsi/templates/field.html.twig' --><div class="field field--name-field-media-image field--type-image field--label-visually_hidden"> <div class="field__label visually-hidden">Image</div> <div class="field__item"> <!-- THEME DEBUG --> <!-- THEME HOOK: 'image_formatter' --> <!-- BEGIN OUTPUT from 'themes/tsi/templates/image-formatter.html.twig' --> <a href="/exploringourfluidearth/sites/default/files/M1U6-Fig6.11A-HighTideEnsenada.png" target="_blank"> <!-- THEME DEBUG --> <!-- THEME HOOK: 'image_style' --> <!-- BEGIN OUTPUT from 'core/themes/classy/templates/field/image-style.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'image' --> <!-- BEGIN OUTPUT from 'themes/tsi/templates/image.html.twig' --> <div class="imgpost"> <span class="img-overlay-lightbox"></span> <img loading="lazy" src="/exploringourfluidearth/sites/default/files/styles/quarter_200w_/public/M1U6-Fig6.11A-HighTideEnsenada.png?itok=Q7SmhNgk" width="135" height="70" alt="&lt;p&gt;&lt;strong&gt;Fig. 6.11.&lt;/strong&gt;

Because the moon is nearly overhead in Ensenada, the observer is located where the tidal bulge is at its maximum and will experience a “higher” high tide of 2 m (Fig. 6.11 A). As the earth rotates, Ensenada will move away from the tidal bulge. Around 6 a.m., approximately 6 hours after high tide, the person in Ensenada will experience a low tide of 0 m. Around noon, approximately 12 and a half hours after the first high tide, the Mexican Pacific coast is as far away from the moon as it will get and will experience another high tide (Fig. 6.11 B). But this second high tide will be lower, only 1 m (see Fig. 6.11 C). This is because the tidal bulges are in line with the moon, and the moon is not directly above the Earth’s equator. At 12:30, the person in Ensenada is not located in near the tidal bulge maximum. Valparaíso, Chile, located 33˚ south (S) of the equator and marked with a red star in Fig. 6.11 A, is located directly the opposite the moon at noon and is thus experiencing its highest tide of the day at noon. Six hours later, around 6:40 p.m., the person in Ensenada experiences another low tide of 0.5 m.</p> <p> </p> <p> </p> <p> <!-- THEME DEBUG --> <!-- THEME HOOK: 'entity_embed_container' --> <!-- BEGIN OUTPUT from 'themes/tsi/templates/entity-embed-container.html.twig' --> </p><div class="action-background"> <div id="node-1297" class="node node-question-set special-feature-type-question-set contextual-links-region clearfix special-feature-type- " data-embed-button="node" data-entity-embed-display="entity_reference:entity_reference_label" data-entity-embed-display-settings="{&quot;link&quot;:1}" data-entity-type="node" data-entity-uuid="736aa680-8121-402d-87d2-522d95561e35" data-langcode="und"> <div class="embed-type-marker"><i class="icon white"></i></div> <div class="embed-supertitle">Question Set</div> <h2 class="embed-title"> <a target="_blank" href="/exploringourfluidearth/physical/tides/tide-formation-tide-height/question-set-moon-declination-and-tide-height" hreflang="und">Moon Declination and Tide Height</a> </h2> <div> </div> <!-- END OUTPUT from 'themes/tsi/templates/entity-embed-container.html.twig' --> </div></div><p> </p> <h2>Elliptical Orbit of the Moon</h2> <p>The moon does not orbit the earth in a perfect circle.

This period is different from the lunar month, which is 29.5 days (the time it takes for the moon to cycle from new moon, to full moon, and back to new moon). The reason for the time difference between the orbit cycle and the phase cycle, the lunar month, is that the earth and the moon are moving around the sun during these cycles. As the earth and the moon orbit the sun, the moon has to travel a greater distance to be in the same orientation relative to the earth and the sun, making the phase cycle last slightly longer than the orbit cycle.</span></p> <p> </p> <h2><span style="line-height: 1.538em;">Elliptical Orbit of Earth</span></h2> <p>Just as the moon follows a slightly elliptical orbit around the earth, the earth also follows a slightly elliptical orbit around the sun. On average, the earth is approximately 150 million km away from the sun. The earth is closest to the sun during the northern hemisphere winter months (approximately 147.5 million km away; Fig. 6.13). This point is called <strong>perihelion</strong>. During summer in the northern hemisphere, the earth is farthest away from the sun (<strong>aphelion</strong>, approximately 152.6 million km away). The earth completes one orbit around the sun every 365.25 days, a <strong>solar year</strong>.</p> <p> </p> <p> </p> <!-- THEME DEBUG --> <!-- THEME HOOK: 'media' --> <!-- FILE NAME SUGGESTIONS: * media--source-image.html.twig * media--image--half-w-caption.html.twig * media--image.html.twig * media--half-w-caption.html.twig x media.html.twig --> <!-- BEGIN OUTPUT from 'themes/tsi/templates/media.html.twig' --> <article class="align-left media media--type-image media--view-mode-half-w-caption"><!-- THEME DEBUG --><!-- THEME HOOK: 'field' --><!-- FILE NAME SUGGESTIONS: * field--media--field-media-image--image.html.twig * field--media--field-media-image.html.twig * field--media--image.html.twig * field--field-media-image.html.twig * field--image.html.twig x field.html.twig --><!-- BEGIN OUTPUT from 'themes/tsi/templates/field.html.twig' --><div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <!-- THEME DEBUG --> <!-- THEME HOOK: 'image_formatter' --> <!-- BEGIN OUTPUT from 'themes/tsi/templates/image-formatter.html.twig' --> <a href="/exploringourfluidearth/sites/default/files/M1U6-Fig.6.13-ElipticalEarthOrbit.png" target="_blank"> <!-- THEME DEBUG --> <!-- THEME HOOK: 'image_style' --> <!-- BEGIN OUTPUT from 'core/themes/classy/templates/field/image-style.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'image' --> <!-- BEGIN OUTPUT from 'themes/tsi/templates/image.html.twig' --> <div class="imgpost"> <span class="img-overlay-lightbox"></span> <img loading="lazy" src="/exploringourfluidearth/sites/default/files/styles/half_page_width/public/M1U6-Fig.6.13-ElipticalEarthOrbit.png?itok=vg5iRt7t" width="290" height="155" alt="&lt;p&gt;&lt;strong&gt;Fig. 6.13.&lt;/strong&gt; The elliptical orbit of the earth around the sun.

Tidal ranges vary considerably at different points of a coastline due to seafloor features. When oceanic tidal bulges hit wide, shallow continental shelves the height of the tide is usually magnified. Conversely, mid-oceanic islands that rise steeply from the seafloor and do not have continental shelves have smaller tidal ranges. Mid-oceanic islands often have very small tidal ranges of 1 meter or less.</p> <p> </p> <p>In narrow mouthed basins that are connected to the ocean, the tides often rise higher than in wide bays and harbors. This is analogous to pouring an entire can of soda into a short wide glass and a tall narrow glass. The soda will rise higher in the narrow glass, because there is not as much area to spread out as in the wide glass. The same amount of seawater will rise higher in a narrow basin than in a wide-mouthed harbor.</p> <p> </p> <p>The moon’s gravitational pull affects water in every location on Earth, and its influence on the height of the tides is affected by the size of the basin of water. The Pacific ocean basin is large and holds a large volume of water. This means that the moon’s gravity has a large amount of water on which to pull. This is one of the contributing factors as to why the tides in the Pacific tend to be greater than the tides in other, smaller ocean basins and seas.  The underwater geography also has an effect on larger tides experienced in the Pacific ocean basin, as does resonance. The tidal range of an area on the coast of Alaska, which is in the Pacific ocean basin, is greater than the tidal range on the coast of Sweden, which is next to the Baltic Sea, an inlet of the Atlantic ocean basin, even though these areas are located at the same latitude. The underwater geography coupled with the larger volume of water in the Pacific ocean basin are the reason that the tidal range differs between these two places.  The Baltic Sea has much less surface area and is much shallower than the Pacific ocean basin. This is why tidal changes that can be observed in big lakes are minor compared to tidal ranges in the ocean and why tides cannot be observed at all in small lakes.</p> <p> </p> <p> <!-- THEME DEBUG

A <strong>high tide</strong> is the stage when the tidal crest arrives at a particular location on shore, raising the local sea level. A <strong>low tide</strong> is the stage when the trough arrives, lowering the local sea level. A <strong>flood tide</strong> is a rising or incoming tide between low tide and high tide. An <strong>ebb tide</strong> is a falling or outgoing tide between high tide and low tide. The vertical distance between high tide and low tide is the <strong>tidal range</strong>.</p> <p> </p> <p>Tides are predictable because they are produced by a combination of forces that are predictable. These forces are determined by the movements and positions of objects in our solar system, particularly the earth and the moon in relation to the sun. To understand tides, therefore, it is important to understand the movements of the earth and the moon relative to the sun.</p> <p> </p> <p> </p> <p> <!-- THEME DEBUG --> <!-- THEME HOOK:
