Construct navigation triangles</strong></p> <ol><li><strong>Navigation triangles</strong> are tools used by navigators to plot courses and transfer compass bearings within a nautical chart (Fig. 8.29).<br />  </li> <li>Construct a pair of navigation triangles from a single index card.<br /><ol start="1" style="list-style-type: lower-alpha;"><li>On the blank side of the index card, mark the two longer (5-inch-long) edges with “X” marks (Fig. 8.29).</li> <li>Mark the two shorter edges of the index card with “O” marks (Fig. 8.29).</li> <li>Draw a diagonal line using a ruler across the index card from the bottom-left corner to the top-right corner.</li> <li>Mark the two halves of the index card (now two right triangles) “#1” and “#2” (Fig. 8.29).</li> <li>Carefully cut the index card along the diagonal line to separate triangle #1 and triangle #2.</li> </ol></li> </ol><p> </p> <p><strong>B. Triangulation</strong></p> <p>Imagine that you are lost and floating in the middle of Kāne‘ohe Bay, Hawai‘i. You are trying to reach He‘eia Kea Harbor safely without striking any coral reefs.</p> <p> </p> <ol><li>In order to navigate safely, you will first need to determine your current location or position on the nautical chart (Fig. 8.31). This can be accomplished through triangulation. <strong>Triangulation</strong> is a technique used to determine the location of one unknown point by using the locations of two or more known points around it.<br />  </li> <li>You can see two distinct landmarks around you:<br /><ol start="1" style="list-style-type: lower-alpha;"><li>The peak of Mokoli‘i (Chinaman’s Hat) is at bearing 20° on your compass.</li> <li>Kualoa Point is at bearing 340°.<br />  </li> </ol></li> <li>Where are you in Kāne‘ohe Bay? Use the navigation triangles to transfer or shift the landmarks’ compass bearings to the nautical chart.<br /><ol start="1" style="list-style-type: lower-alpha;"><li>Align the X-marked edge of triangle #1 to the 20° mark on the compass rose. The edge must pass directly through the cross in the center of the compass rose (Fig. 8.30 A).</li> <li>Press down firmly on triangle #1 to maintain this original compass bearing.</li> <li>Place triangle #2 next to triangle #1 with their unmarked diagonal edges touching. The two X-marked edges should remain parallel to each other (Fig. 8.30 B).</li> <li>Carefully slide triangle #2 along the diagonal edge until the X-marked edge reaches the map symbol for the peak of Mokoliʻi (Fig. 8.30 C). Take caution not to move triangle #1 while sliding triangle #2. Always keep the two X-marked edges parallel and opposite from each other.</li> <li>Use the X-marked edge of triangle #2 to draw a straight line through the map symbol for Mokoli‘i (Fig. 8.30 D). If needed, you can use a ruler to extend the X-marked edge of triangle #2. Use a ruler to lengthen this straight line across the entire nautical chart. Label this line with the compass bearing “20°”.</li> <li>You have now used the navigation triangles to transfer the compass bearing from the compass rose to the map symbol or reference point (e.g., Mokoli‘i). Your ship’s position is somewhere along this line.<br />  </li> </ol></li> <li>Repeat steps 3a through 3e for the tip of Kualoa Point, spotted at bearing 340° on your magnetic compass.<br />  </li> <li>Locate the point on the nautical chart where your two drawn lines intersect. Label this point as “A”. This point marks your ship’s current location.</li> </ol><p> </p> <p><strong>C. Plotting a course</strong></p> <ol><li>On the nautical chart, locate the boat channel closest to point A. Boat channels should have deeper water (indicated by white color) and are located between two dotted lines on the nautical chart.<br />  </li> <li>Mark the closest point of the near boat channel as point “B”.<br />  </li> <li>Use a ruler to draw a straight line between point A and point B.<br />  </li> <li>Determine the compass bearing for the course now plotted between point A (your current position or location) and point B (the nearest boat channel).<br /><ol start="1" style="list-style-type: lower-alpha;"><li>Line up the X-marked edge of one of the navigation triangles to the A-to-B course line.</li> <li>Use the second navigational triangle to transfer the compass bearing of the A-to-B course line to the compass rose on the nautical chart (this technique is the reverse of the procedure described in Part B above).</li> <li>Write the compass bearing above the A-to-B course line.</li> </ol></li> </ol><p> </p> <p><strong>D. Determining course distance</strong></p> <ol><li>Determine the distance of the course plotted above from your current position (point A) to the nearest boat channel (point B). <ol start="1" style="list-style-type: lower-alpha;"><li>Use a ruler to measure the length of the A-to-B course line.

the latest coastal conditions. While older tidal measuring stations used mechanical floats and recorders, modern monitoring stations use advanced acoustics and electronics (SF Fig. 6.16). To determine water level, modern recorders send an audio signal down a sounding tube and measure the time it takes for the reflected signal to travel back from the water's surface. In addition to measuring tidal heights more accurately, the modern systems also record other oceanographic and meteorological parameters such as wind speed and direction, water current speed and direction, air and water temperature, and barometric pressure.</p> <hr /><p>In the United States, the National Oceanic and Atmospheric Administration (NOAA) operates over 3,000 tidal monitoring stations from Guam to Bermuda.

However, the seasons are determined primarily by the tilt of the earth, not the distance between the earth and the sun. The earth is tilted on its axis approximately 23.5˚ relative to its orbital plane around the sun. When a hemisphere is tilted toward the sun, that hemisphere receives more direct sunlight and experiences summer. At the same time, the other hemisphere is tilted away from the sun and receives less direct sunlight, experiencing winter. The northern hemisphere is more directly exposed to the sun’s rays during June and July (summer in the northern hemisphere, SF Fig. 6.11 A). The southern hemisphere receives less direct sunlight during these months, resulting in winter. Exposure to direct sunlight alternates as the earth revolves in its orbit around the sun. The southern hemisphere is most directly exposed to the sun’s rays in December and January (SF Fig. 6.11 B). During this time the northern hemisphere experiences winter as it is receiving indirect sunlight.</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-SF%20Fig6.11A-SummerSolstice.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-SF%20Fig6.11A-SummerSolstice.png?itok=6TJaxLEs" width="290" height="190" alt="&lt;p&gt;&lt;strong&gt;SF Fig. 6.11.&lt;/strong&gt;

This means that it takes the same amount of time for the moon to rotate once about its axis as it takes for the moon to make one orbit around the earth. The moon’s rotation and orbital period are both just under four weeks. This synchronous (or same) rotation causes one side of the moon (the side with “the man in the moon”) to always face Earth (SF Fig. 6.7). This is called the near side of the moon. Most of the major moons in our solar system rotate synchronously with their planets.</p> <p> </p> <!-- THEME DEBUG --> <!-- THEME HOOK: 'media' --> <!-- FILE NAME SUGGESTIONS: *

The alignment of the sun and the moon casts a full, dark shadow on the earth, called an <em>umbra</em>, and also a lighter, partially blocked shadow, called a <em>penumbra</em>. From Earth, the moon, and sun appear to be nearly the same diameter in the sky, because even though the sun is much bigger, it is much farther away from the earth. During a total solar eclipse, it looks like the new moon is covering the sun (SF Fig. 6.4 A). Total solar eclipses are rare because the sun, the moon, and the earth not only have to be lined up (which only happens about every six months), but the moon has to be closer to the earth than average in order to completely block the sun. On average, a total solar eclipse occurs somewhere on earth every 18 months. However, when you take into account the fact that the moon’s umbra is, on average, under 150 km wide, a given location only experiences one every 360 to 410 years (SF Fig. 6.4 B). Partial solar eclipses (SF Fig. 6.4 C), caused by the much larger penumbra, or partial shadow, are more common.</p> <p> </p> <!-- THEME DEBUG --> <!-- THEME HOOK: 'media' --> <!-- FILE NAME SUGGESTIONS: * media--source-image.html.twig * media--image--third-266w.html.twig * media--image.html.twig * media--third-266w.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-third-266w"><!-- 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-SF%20Fig6.4A-SolarEclipse1999.jpg" 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/third_266w_/public/M1U6-SF%20Fig6.4A-SolarEclipse1999.jpg?itok=TMCXN73A" width="180" height="164" alt="&lt;p&gt;&lt;strong&gt;SF Fig. 6.4.&lt;/strong&gt;&amp;nbsp;(&lt;strong&gt;A&lt;/strong&gt;) Photo of a total solar eclipse from a location on Earth within the umbra&lt;/p&gt;" title="&lt;p&gt;Image courtesy of &lt;a data-cke-saved-href=&quot;http://en.wikipedia.org/wiki/File:Solar_eclipse_1999_4_NR.jpg&quot;

Thus, an observer on Earth can see the full moon passing through Earth’s umbra or penumbra. During a total lunar eclipse, the moon often appears red because the light that reaches the earth has traveled through the Earth’s atmosphere and been bent (or refracted) toward the moon. The earth’s atmosphere acts to filter out blue light, leaving proportionally more red light, causing the moon to appear red (SF Fig. 6.6). (Similar reasoning can be used to explain why the sun appears redder near sunrise and sunset than at midday.) Lunar eclipses are much more common than solar eclipses and last longer because the earth is much larger than the moon. When they occur, lunar eclipses can be seen from half of the earth, weather permitting.</p> <p> </p> <!-- THEME DEBUG --> <!-- THEME HOOK: 'media' --> <!-- FILE NAME SUGGESTIONS: *

Specialist at the Lunar and Planetary Institute, NASA Goddard Space Flight Center</em></p> <p> </p> <p>The current prevailing hypothesis for how our moon formed is known as the giant impact hypothesis. The giant impact hypothesis states that the moon was formed from debris caused by the collision of a Mars-sized object with Earth at least four billion years ago. Many planets in our solar system have moons, but Earth’s moon is the largest relative to the size of the planet. The moon is one-quarter the diameter of the earth. The moon’s size and relatively short distance from the earth make it the largest object in the night sky. In addition to its size, the moon is prominent because it is very bright. However, the moon does not produce light; but rather, reflects the light of the sun. The moon’s prominence and regular cycle of phases have contributed to its influence on language, art, mythology, and the calendar. The moon has not only inspired humans but has also contributed to our existence by making Earth a more habitable planet. For example, the moon moderates the wobble of the earth’s axis, which, in turn, stabilizes the climate.</p> <p> </p> <p>One of the reasons for studying the moon is to understand more about the origin and geologic history of the earth. The moon provides information about how Earth formed. Because the moon’s surface is relatively stable and the moon has no wind or rain, its history of meteoric bombardment is preserved in its craters. This history has been largely erased on Earth by mountain building, volcanism, weathering, and erosion.</p> <p> </p> <p>Early astronomers thought the large dark spots on the moon were oceans. Each lunar dark spot was named <em>mare</em> (pl. <em>maria</em>), the Latin word for “sea.” Further explorations of the moon revealed that these dark regions were formed by ancient volcanic eruptions and appear darker because of their basaltic rock composition. This makes them less reflective than the highland areas which are composed of light colored rocks.</p> <p> </p> <p> </p> <!-- THEME DEBUG --> <!-- THEME HOOK: 'media' --> <!-- FILE NAME SUGGESTIONS: *
