Deep Sea Sounding On Challenger

Hedy shared her idea with George Anthiel, a composer, writer and inventor. And in 1942 was granted a patent for it. When Hedy took her invention to the military they rejected her idea because she was a Hollywood scarlet. The military didn’t accept her idea until the 1960's after her patent expired. And It was later rediscovered independently and used in ships sent to Cuba during the missile crisis of 1962. George gave all the credit of their invention to Hedy. Hedy had listened to her first husband when he talked about torpedoes so it was easy for her to come up with her

Not only did we have ships, but we had a device called the Turtle. Invented nearly 150 years before, it was not until the Revolutionary War that the submarine would be used in combat. A man named David Bushnell would develop the Turtle to deploy underwater mines. The Turtle would fail all of its missions and would be lost at the Battle of Fort Lee when the ship transporting it would be sunk. “Despite the failures of the Turtle, General George Washington gave Bushnell a commission as an Army engineer…After the war, he became commander of the U.S. Army Corps of Engineers.”(History 1).

Although Drebbel’s submarine was used as a tool for underwater exploration, inventors soon recognized their military potential. Bishop John Wilkins describes the strategic advantages of submarines in Mathematical Magick written in 1648. The advantages he described include the ability to travel invisibly, safety from tides and covert travel against a Navy of enemies. Overall, submarines were advantageous to science, and to the

Grey, the sea stretched for acres. Beneath the oceans topography, shoals of fish swam through and around the ship wrecks in a frenzied motion. Here, all stood still. Only slightly did my rowing boat rock, creaking in the tide. We rolled to and fro slightly; the seaweed twisted and writhed beneath the hull. Like a snake, it squirmed away, coming to rest only after we had passed. The oars made long, slow and deliberate wakes through the lagoon. I stopped sculling; the boat glided silently towards the stony, promontory beach. We had landed.

Robert Ballard was one of the great explorers who discovered numerous secrets about the deep sea and science while encountering new creatures and natural resources as he explored and exchanged new ideas of using technology and incorporating it into his discoveries. Ballard is known for two of his most famous findings: the shipwreck of the Titanic and the Bismarck. The ideas of using technology to assist with his findings helped him create his own equipment with his team to find out more about the deep sea. The idea came from previous discoveries where he saw the Earth’s curst crack and how it affected marine life, geology and geophysics. This led him to become intrigued and continue on to more research to show the world the mysteries of the ocean. Ballard’s exploration of the deep sea provided encounters that led to a better understanding of plate tectonics and the environment, the use of technology to find historical treasures, and the preservation of history left behind in the deep sea.

The mode of transportation was a huge outrigger canoe that was at the mercy of the ocean. The navigator, tracked time-honored information taken from the stars, from ocean swells, clouds, birds and other signs with only never-ending ocean surrounding the canoe.

James I. Clake’s book, coffin at forty fathoms tells the story of an unusual sea rescue when the United States submarine squalus sank on may twenty third one thousand nine hundred and thirty nine. The navy sought help from lieutenant commander Charles “Swede”. Momson had tried to convince the navy that his invention a sort of diving bell that would attach to the escape hatch of the submerged submarine would save many, otherwise, doomed live after the navy located. The squalus at two hundred and forty three feet below the ocean’s surface. Momson and his team worked quickly, first a diver attached a long cable to the squalus escape hatch when the diver returned the rescue team lowered the bell. The author described the rescue in these words;

often will people think of a nautilus, an organism that is a distant cousin of cuttlefish and squid. These organisms have been dubbed "living fossils" and have been on earth for about 500 million years. The nautilus tends to in front of coral reefs, deep in the ocean. The long existence of the nautilus has allowed its mesmerizing spiral shell to be embedded in some rocks and has become a part of the fossil record.

Biologists and engineers eventually were able to follow fish using acoustic tags. These tags created sound waves that could be detected by underwater microphones attached to boats. The tags measured how the fish moved through it's environment.

Believe it or not there is still advancements in today’s submarine that were apart of some 1920s submarines. One of those said advancements would

The bottom of the ship was divided into 16 watertight compartments equipped with automatic watertight doors to protect it self. These doors could be closed immediately if water were to enter into those sections to prevent any other spread and control the

Throughout Challenger Deep, Neal Shusterman uses oceanic language in order to connect Caden’s real world to his hallucinations. The language Shusterman uses helps the reader in connecting Caden’s realities, adding a sense of depth in his thoughts, and creating a feeling of suspense in the reader. Oceanic themes are often seen throughout the novel since the ship is Caden’s other reality, and Shusterman uses this theme throughout Caden’s real world as well. Scenes in the book have dialogues that include Caden’s father telling him that “the ship sails soon” along with multiple others (Shusterman 130). This type of language can be seen throughout the book, and helps the reader in connecting certain actions to Caden’s hallucinations. Along with

This experiment proved, or supported, the fact that pitch is inversely affected by length. This basically means that, when length goes up, pitch goes down, and vice versa. These results can be helpful in real life in many ways. In designing or creating instruments, the relationship between pitch and length is extremely helpful and important. For example, the reason why a piccolo can play higher notes than a regular flute is because of its length. Since the piccolo is shorter, it can reach higher pitches than the flute. This is the case with many other

This includes a range of echolocation clicks in the dolphin sonar system used to identify objects underwater.

Essentially it is stating that these structures have a great advantage for detecting underwater disturbances if there is no degree difference of the whisker verse the directionality of the vibration. However, this study only takes into account the angle and association of post-mortem samples. Since the extensive research was not conducted on live samples aside from briefly videotaping some species of pinniped, it is unclear if there is a distinct difference in functionality between the undulated and smooth vibrissae. Furthermore, another downfall of the similarity of not finding a formidable function of undulated vibrissae as the research states is that there is no clear advantage in efforts of noise reduction or vibration sensitivity. Their findings may be important for future research to possibly find morphological differences in vibrissae to access their complete
