Intro During the past centuries numerous scientists have devoted their lives to charting the world’s oceans. Longitude and latitude can provide accurate locations and distances, which proved crucial in numerous scenarios. The objective of this lab was to learn how to read and create charts. Overall the lab contained realistic situations and important information that has aided the study of the world’s oceans. The lab was also aimed at applying the information we learned in class to actual charts and data.
Method
During the course of this lab I used tools such as a parallel rule, a ruler, a compass, and a map of the Atlantic ocean. The lab consisted of three parts including charting a rhumbline, determining the course of a sailboat, and studying the migratory patterns of Green and Loggerhead

In the first part, I chose a line that was close to the coast of Africa. I used a piece of lined paper and marked the changes of depth. Then I found the distance in kilometers from the mark to point A by using the latitude measurements. Next, I charted the points to create a chart of the depths my line crossed. In part two we found the course and distance of different sailing routes. On the trip from Black Point to Biscayne Bay I used the parallel rule to find that the course needed was 132 degrees southeast. I found that the distance was 7 nautical miles by looking at latitude on the map. The second question involved current, so I used the chart on the back of the packet to find that 135 degrees southeast was the course needed to be taken by the sailboat. The chart helped me make a triangle with the same central angle as the intended non-current course of the boat. Then with the parallel rule
The only landmarks available to the eye are dozens of miles of ocean waves, occasionally broken up by an ocean going freighter or container ship that might sometime plod past the area, on their way inbo...
Now that we’ve made our way through the journey of Ken Jennings’ incredible book I feel as if it’s important for me to try to sway you to become more involved in geography. It’s a truly fascinating subject and can take you places you never thought you could ever visit. If you don’t want to leave your home, at least buy an atlas, map, or visit Google Earth. You never know what you could discover in your journey. If you don’t think maps or an atlas is your thing, you never know if you never try. Jennings created a journey, for me I would have never cared to take had it not been assigned as a college class assignment, but now I’m so glad I did. Jennings shined a different light on geocaching, and map hunting. He made it fun, interesting, and overall thrilling.
Dava Sobel’s novel, Longitude: The True Story Of A Lone Genius Who Solved The Greatest Scientific Problem Of His Time is a history of the scientific battle to obtain a method of finding the exact longitude of a specific location. Knowing the longitude of a location may seem unimportant, but in fact it is vital. To fully understand the work that went into this effort, first, one must understand the basic principles for determining location on Earth.

El Niño is detected using satellites, moored and drifted buoys, and a sea level analysis.
America at this time consisted of overland travel and ocean travel. The journey all the way across the continent by land was risky and extremely difficult. It consisted of passing over mountains, plains, rivers and deserts. It also was a very timely process. In ocean travel, each ship would have to take the route around Cape Horn at the bottom of South America. This timely trip would have an average time of six months. They could also cross the Isthmus of Panama and risk getting yellow fever and other diseases.
Hawaiian Navigation How did the Polynesians find their way to Hawaii, over two thousand miles from any other land? Was it over population at home, or political turmoil? Whatever reason for leaving, these people used amazing knowledge and skill of the ocean and of the sky to navigate them to this new land. They faced the unknown and braved the wide-open ocean for long periods of time. The real focus in this paper is on the navigation techniques that they used in these voyages throughout the Pacific.

Literary Analysis of “Charlie” by Lee Marcle In the story “Charlie” by Lee Marcle, the author develops the theme that when one knows one's identity, no matter how systems attempt to destroy it, it will always be within them. This theme is conveyed through the use of varying sentence structures, symbolism, and diction, which can be particularly noted in its use when describing Charlie’s life in residential school, his daydreams during class, and his rigorous journey toward home. The diction, symbolism and sentence structure used when describing Charlie's experience in residential school demonstrates the struggle to maintain a connection to one's identity. For instance, the portrayal of the Indigenous children's daily interactions with their principal terrifies them: “‘EAT
So, in 1882 the U.S Fisheries Commission’s Steamer called the Albatross was built. This was the first vessel built by any government in which it’s one and only purpose was to help conduct oceanographic research. The only problem was that the United States did not know what to do on a expedition. This is where America went on its first expedition. This is the first expedition in which two different countries worked together on a expedition.
The Age of Exploration began as a result of new technologies that guided explorers during sea voyages. Explorers used many tools and technologies during The Age of Exploration, to explore and make discoveries. Technology and tools that explorers used, included, caravels, compasses, astrolabes, and even sponsors. A sponsor is a person who gives money for an undertaking, such as a voyage. A sponsor would also provide money for materials needed for the voyage, such as, caravels, and other necessities. A caravel is probably the most important material needed for a voyage. A caravel is a ship designed for long voyages. Caravels have both square sails, and triangular lateen sails. However, they each provided/allowed different things. Square sails provided power, when lateen sails allowed quick turns. The compass, a Chinese invention, allowed sailors to track their direction. On the other hand, an astrolabe, an ancient Greek invention, improvised by the Arabs, would measure the angle of the stars above the horizon. This would help sailors find their s...

The Bermuda Triangle, an area stretching from the tip of Florida, to Puerto Rico, all the way to the Bermuda islands, is a region within the Atlantic Ocean that has had many planes and ships evaporate into thin air without little to no explanation. Even though this region has had various incidents, it is still not represented upon maps of any sorts. Many theories have arisen about the triangle, but only a few out of those are actually plausible. This paper will go over a few non credible and reasonable theories. The Bermuda Triangle should be established as a hazardous zone due to its impulsive behavior, and should be implemented on maps, to thwart or at least reduce future accidents.
There are several physics concepts that can be used to explain how sailboats function the way they do. These include Newton’s laws and vector subtraction. The physics behind sailing are dependent upon the position of the boat and the sail relative to the wind, yet all of the physics concepts at work at any given point in time during sailing will be the same. The first position (as well as the easiest to comprehend) is downwind sailing. This immediately involves Newton’s third law, which states “for every action, there is an equal and opposite reaction”. This is because the sail will push back on the wind as they come in contact (action and reaction). This occurrence results in the smooth and comfortable motion of the boat in the direction of the wind, yet it will never be as quick at the wind (ie. wind decelerates, entire sailboat accelerates. Boat can never possibly achieve and sustain an...
