In Jacques-Yves Cousteau’s time as an oceanographer he and his partener Emile Gagnan a french inventor, created the aqualung a portable breathing apparatus, consisting of cylinders of compressed air then strapped onto the divers back feeding the air through a tube then into mask or mouthpeice witch allowed divers to stay underwater for longer periods of time(Biography.com/A&E telivision network para 8) also created the Calypso a converted british minesweeper (the editors of encyclopeadia britannica para 4). This submarine was made for sea floor exploration. It was easily meunuverable and had many underwater cameras(the editors of encyclopeadia britannica para 2).
In 1936 Jacques-Yves Cousteau found himself in a almost fatal automobile
In the American Revolutionary War, a manned underwater craft named the American Turtle (or the "water-machine") was used against the British Navy. David Brushnell designed this ingenious machine in 1771. The submarine was a one manned, egg-shaped vessel which was propelled by hand-operated screw-like devices. It was bottom-heavy in order for it to remain upright. The operator would plant a submersible mine that could be triggered by a simple clockwork mechanism. He could paddle away after he attached the magazine of gunpowder onto the enemy ship. The operator could stay under for about thirty minutes
Archaeology is a continuously evolving field where there is a constant stream of new branches and excavation methods. Due to the influx of new technologies and innovations in recent decades, archaeologists have been able to excavate previously inaccessible areas. For example, new diving equipment and tools such as proton magnetometers, side-scan sonar, sub-bottom profiler, and miniature submarines have allowed archaeologists to dive into the deep depths of the ocean. As a result, the branch of underwater archaeology was created to search for shipwrecks and other artifacts on the ocean floor. Underwater archaeology’s role has increased in recent years as it allows archaeologists to more accurately interpret the past by supplementing information gained through traditional land excavations.
used by the boat was essential for communication and the safety of its passengers. The Titanic,
Throughout the years submarine technology has advanced throughout the years from the original military submarine the turtle to the German u boats during WWII modern nuclear power submarines that we have today. These developments have required a lot of technological improvements. To make the u boats work the Germans need better battery and electrical motor technologies and the nuclear submarine obviously needed nuclear technology. Submarines have always been an innovative way to win the navel war.

Robert Fulton invented the first submersible submarine. This new invention put Fulton’s steamboat ideas on hold. The submarine was for the fast growing British Navy. The British Navy needed an underwater device that could swim under enemy ships and set off explosives. Fulton was American and this invention would make him a celebrity back in the states. Fulton was the head of a 5-10 man team who was inventing this new machine. Fultons main partner was a man named Robert Livingston. Livingston obtained a license for these new machine. This put lots of pressure on Fulton to make sure the sub works. After a couple of tests the mission was completed without any big mistakes. The new Submarine could submerge for 5 hours carrying two men. It was also
Divers cannot put the equipment on and immediately dive in. Before diving there are a series of procedures the diver and their partners must do before going down. In addition, the further down the diver dives the more pressure pressing down on the diver which lessens the amount of oxygen in the scuba tank. Therefore, the further down the diver dives the less time the diver can spend on the bottom. But now, by far the largest group of divers is “Recreational Divers”. These dives are practiced at depths of less than 130 feet, from these depths, divers can make a straight ascent to the surface. Diving beyond this limit requires advanced training. Also, when diving the diver must take into account the amount of time spent descending and ascending in the water. If the diver descends too quickly the pressure can deflate their lungs and cause problems. Similarly, if they ascend too quickly nitrogen bubbles can form under the diver’s skin causing bends or decompression sickness. This sickness can be extremely harmful and possibly fatal. Lastly, a dive watch or computer is needed to calculate the amount of oxygen left in their tank and the depth. Dive computers help the divers be aware of their conditions and keep them
Many classic books of literature of the French Enlightenment era comes from the famous author Francois-Marie Arouet, better known as his pen name, Voltaire.The French author was born on November 21st, 1694 and died May 30th, 1778 in the city of Paris. He started school at the Jesuit College of Louis-le-Grand at the age of 10 and graduated in 1711 with a motive of being a writer. However, Voltaire’s father did not agree with his choice of study and wanted Voltaire to study law. He went back to school to study law for another two years after his graduation. Voltaire was sent to The Hague, Netherlands in order to act as a secretary to the French ambassador at the time. During his visit, he became infatuated with Catherine Olympe de Noyer. Due to his love affair, Voltaire was discharged from the Dutch country to France “disinherited, and threatened with exile to the New World.” (Stanley 67). A few years later, Voltaire was accused of writing two satiric poems against the French regime because of his reputation in writing and was imprisoned at the Bastille from 1717 to 1718. During the time spent inside the prison, Voltaire wrote the tragedy called the Oedipe. After being released, Voltaire adopted the new of De Voltaire due to the commonness of the original name. His father died in 1722 and was released from his control. Voltaire also met Jean-Jacques Rousseau, a Genevan philosopher, the same year in Brussels, Belgium. From 1726 to 1728, Voltaire was sentenced to another term in the Bastille and exiled to England due to an encounter with “his growing squadron of enemies and spearheaded Chevalier de Rohan” (Stanley 67). He met the author by the name of Jonathan Swift during his exile. Voltaire was able to re-enter France in 1729, and p...
Scuba diving itself can be challenging at times. Imagine having a difficult task, like welding, to perform at the same time as scuba diving. This is a task that can cost you your life if not done correctly and as safely as possible.
Science fiction and the sea are surprisingly linked in their history. Early attributes can be noted as early as Defoe's Robinson Crusoe, which experimented with fantastic elements, made realistic by adhering to real world rules and practices1. Jules Verne's 20,000 Leagues Under the Sea likewise used true historical detail “to convey a sense of existence... through three layers of operability: existing technology, those plausible through their analogy with the existing, and the fictive,”2. The experiences of both Heinlein and Herbert in WWII provided them with experience and knowledge to draw on to create realistic predictions in their works, which wer...
Buoyancy, how easily a person sinks or floats, is definitely a huge part of scuba diving. It determines how deep a person stays underwater. To control this, divers wear weights and inflatable neckwear called buoyancy compensators. Depending on how many weights a person is wearing; they sink to a certain depth and stay there. The more weights, the farther down they go. The buoyancy compensator, once inflated, rises the person back up to the surface. The more accessories, such as weights, a person wears, the lighter they feel in water and the easier they sink.

The very first scuba dives performed were in search for jewelry and very short until a way to breathe underwater for longer periods of time was invented. In order for the divers to stay submerged underwater longer, they used a hollow reed. Research shows that later on, “helmets were made of metal to withstand even greater water pressure and divers went deeper” (MarineBio.org 1). These improvements in technology gave divers a smoother dive, allowing them to enjoy more time submerged deeper in the ocean. Along with divers being able to stay under longer and enjoy the underwater sea life, there came some dangers that were not recognized and are potentially serious if one does not take diving serious.
Scuba diving is a sport in which you can lose yourself to the beauty of the underwater world and escape gravity for a short time. You can wander among kelp forests or swim with sleek noble sharks. You can find a fortune in Spanish ducats or lose yourself in the beauty of the underwater realm. Some may say though that diving is an extreme sport and that it is too risky for anyone, it's just for the wild hooligans. Scuba Diving is a safe and enjoyable hobby despite the small risk involved. Haven't you ever wondered what it was like to swim with the fish? Or see why all of those people would want to were all that funny looking gear and go under the water?
