The oceans are a mysterious place, more so than outer space. Oceans are highly unexplored with only five percent of it, has been explored. That leaves ninety-five percent to be discovered. Despite the oceans playing roles in our climate to our air we breath we have not made it down too far.
Filmmaker and explorer James Cameron took on Challenger Deep, the deepest spot in the ocean. Cameron made his descent into Challenger Deep at five fifty two local time. His descent took him two hours and thirty-six minutes to reach a record setting depth of 35,756 feet or 10,898 meters down. This is where he was to rendezvous with a vehicle to study animal life down below.

Sadly, the only things that scientists have learned about this where light can reach. Light from the sun can only go down to one-thousand meters. At this zone absolutely no sunlight can reach these depths. This explain why scientists have not been able to explore at this depth. The use of powerful lights and submersibles, allowed us to go down further than ever before, but without the light to see going down below one-thousand meters is useless. To reach the depths of the Titanic the scientists use submersible robots to reach the vessel two miles down.
The Ocean is divided in three different zones. The Sunlight or euphotic, in this zone light can easily penetrate from Sea level to two hundred feet down. Next, is the twilight zone or the dysphotic zone. This zone extends down from two hundred meters down to one thousand meters, light doesn 't make it through this zone but it does reach here. Photosynthesis cannot happen at these depths. Finally, there is the midnight or aphotic zone, light does not reach this depth. (How far does light travel in the ocean,2015)
The midnight zone is where humans have problems exploring, due to the fact that light cannot reach there. Lights are hooked up to submersibles to to try and explore the mysterious world of the midnight zone. New creatures have been discovered in this zone, and more are being found every day.
Marine Biodiversity is necessary for oceans to keep in check and functioning

NOAA created the Office of Ocean Exploration (OOE) in response to the Ocean Exploration Panel being convened, the OOE organizes and facilitates research expeditions to marine sanctuaries off the coast of the United States. Many important expeditions have been sited in these marine sanctuaries like the marine sanctuary in Cape Hatteras, North Carolina. This sanctuary is the USS Monitor from the Civil War. Another sited is Thunder Bay National Marine Sanctuary in the great lakes region finding shipwrecks in the Great
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.
There are mysteries which man can only guess at, which may only ever truly be solved in part; the SS Edmund Fitzgerald’s sinking is one of them. At the time it was launched in 1958, the 729-foot long, 75-foot wide freighter was the largest ship to ply the Great Lakes. Although, on November 9, 1975 the ship embarked upon what would become its final voyage. She was carrying 26,000 tons of iron ore pellets and bound for Detroit, and though the day was bright, in her path laid great turbulence. On November 10, at 1:00am, the first signs of trouble appeared, and prevailed into the afternoon. As the waves built, luck was neither with the ship nor the crew. At 7:10 PM, Captain McSorley delivered what was to be his final message "We are holding our own." Ten minutes later, the Fitzgerald could neither be raised by radio, nor detected on radar, and no distress signal was received. With that, the ship and crew of 29 men sank to the bottom of Lake Superior. Several expeditions have been mounted to the wreck and have been the subject of some controversy. There are many theories for how the Fitzgerald found itself hundreds of feet below the water; however none of them have been proven indefinitely. One possible cause of this disaster includes the ship crossing the Superior Shoal, with water as shallow as 22 feet. Additionally, the ship may have suffered a stress fracture and broke apart on the surface. Another possibility is that the ship succumbed to the forces of the Three Sisters, a Lake Superior phenomenon, consisting of massive waves. These current theories are merely conjectures, and since each holds the possibility of being true, it cannot yet be determined which one actually is.
Rachel begins by stating that when tides or waves occur in the ocean they don’t just effect the surface but also the deepest levels of the water. How would you know for a fact that the wave currents run deeper than just the surface? Proof given by her illustrates
April 14, 1912, the Titanic set sail for a maiden voyage. Some of the people on board never thought that it would be goodbye forever. The Titanic was heading to New York City from Southampton, England. Why does the Titanic now lay at the bottom of the Atlantic Ocean? Historians believe that the Titanic sank because of human error. They believe that it was Captain Smith, the lookouts in the crows nest, and Thomas Andrews fault.
Review: The opportunity and endeavor of exploring the Earth’s oceans can reap great rewards for mankind and unravel many of the mysteries that the Earth has left to discover.
first of all, in an article called, “Why Exploring the Ocean is Mankind’s Next Giant Leap” by Philippe Cousteau it explains two going down to the deepest part of the ocean, the Mariana Trench, but this is largely forgotten today. In this article it also explains how unbelievable it is that people are focusing on space travel but we don’t know
From the surface to its deepest depth the ocean is 11km deep, and with this distance comes a vast change in physiological feature of fish as they try to survive the changing conditions.
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.
Our oceans are the most productive and more than likely the most helpful environment on the planet today. Oceans not only supply our ozone with life supporting oxygen, control the earth’s weather patterns, it also is home to over a million different species ranging from mammals, invertebrates, to microscopic plankton. The ocean is a very diverse environment and it is very important to keep the ocean and all off its creatures alive and healthy. There are many reasons for this, but the main reason is that what we do in our waters will directly effect the way we live.
While trying to make it through the ship, they are faced with many obstacles. The ship is filled with water, flash fires, debris, dead bodies, and more. And time is running out, they need to make it to the bottom of the ship before the entire thing sinks.
1620 AD A Dutchman, named Cornelis Drebel, built the first successful submarine with a wooden frame that was encased in leather. This craft was able to carry 12 rowers and eight additional people, totaling the people in the craft to 20. This vessel was capable of diving to depths of 20 meters and could travel 10 kilometers at a time. This submarine was tested in the Thames River, and would often remain submerged for hours. This submarine was the first to address the problem of oxygen shortage.

All oceans contain salt water and other minerals. The Pacific Ocean has the largest body of water in it. It spreads nearly halfway around the world. The Pacific Ocean is also the deepest ocean out of all four oceans. The Atlantic contains the second largest body of water. Next is the Indian Ocean, which is on the borderline of being a big ocean and a small ocean. Last is the Arctic Ocean, which by all means is the smallest ocean of them all, and the shallowest.
