In our lifetime, the ocean has remained untamed and unexplored. “Modern Day” technology has only been able to come so far in venturing out to sea and to the world below the surface. However, in the past 10 years this has all been changed. With research being done throughout the world studying the movement and anatomy of fish, the gap between the surface and the sea floor could be speedily lessening. For years humans have marveled at the speed and grace of most marine life. The lack of drag, the force propulsion, and the ability to live at such impossible depths have been forever the envy of submarines and sea explorers. After years of observing these incredible functions, researchers are finally beginning to mimic and apply these characteristics to marine technology. These robo-fish hold the potential to make underwater exploration far more accessible, safer, and more efficient due to their naturalistic design.
The first two notable robotic fish were the original robotuna and a fish made by Mitsubishi. While neither of these had ocean exploration in mind while they were being innovated, they did lay the bricks down for the road that would lead to today’s strides forward. The first of the two mentioned fish was created purely to study how fish swim. Through this marvel, we were able to better understand just how fish are able to propel themselves forward in even the harshest of ocean storms or currents. Researchers tried a genetic algorithm to program the fish in a way where it could analyze the vortices to better stabilize. Early incarnations worked poorly but as the system evolved the RoboTuna's abilities improved. Visualization techniques showed that the system had evolved so that the RoboTuna was taking advantage of vortices t...

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
Sonar is an acronym for sound navigation and ranging meaning that sound waves are used to move around and determine the distances between objects. Sonar is a crucial component to many seaworthy vessels. Civilians use it to map the ocean floor, determine water depths, find fish, and locate underwater objects such as pipelines, wrecks and wellheads. Naval uses are to find torpedoes, submarines, sea mines, swimmers, acoustic mines, and navigation. Sound is much more efficient underwater, traveling at a 3,403.5 miles per hour (mph), while only traveling at a meager 769.5 mph through the air; sometimes sound can travel even faster depending on temperature, salinity, density and pressure (Encyclopedia of Marine Science pg. 497). This is due to the close association of between water molecules. Sound is an out...
Seaworld is a giant marine life theme park. The greatest attraction to these many theme park would be those killer whales. In fact, these killer whales are the face of the park. As gigant as these mammals are, seaworld is keeping them in some pretty tight quarters. Mr. Jett and Mr.Ventre says “Wild killer whales can swim a hundred miles daily as they socialize, forage, communicate, and breed. In stark contrast, with little horizontal or vertical space in their enclosures, captive orcas swim only limited distances, with most spending many hours surface resting.” The animals don't have the freedom they need. Also when taking the whales out of their natural habit the whales tend to be depressed and not as heath in that situation. They need their freedom in the big ocean blue. Bring them into the small living units, breeding whales in captivity all for the entertainment of humans. At young ages the calves are taken away from their mothers on to a new seaworld park. Mothers of the calves have even been seen denying their offspring.
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.

Today’s ocean managers are challenged to use scientific knowledge of fish and replace regulated fisheries with well managed sustainable resources. This can be accomplished by implementing tools such as:

Over the course of the existence of humans we have caused quite a lot of chaos. We all have heard that the ocean is one of the most unexplored areas of the planet we live on. Although the vast majority of the oceanic terrain has yet to be pioneered, the notion that it has gone unscathed is ill-informed one. Sharks tend to be forget sometimes, because of their menacing presence. But like all forms of nature, sharks face dangers of their own. Humans seem to be the main culprit of their demise, mostly because of overfishing.
Marine biology is the study of ocean life, estuaries, and wetlands to the extent of marine life and environments. Remotely operated vehicles, underwater habitats, satellites, sonar, computers, fiber optics, and many more are all used in this field of study. Marine biology can prevent the effects of ocean health, planet health, human health, sustainability, biodiversity, research, and product development. The oceans being effected can spread around to the whole world and impact a wide range of people and land masses.
Fishing contains a wide variety of physics. when you cast you are using projectile motion and rotational motion. when you hook a fish it will often use the drag from the current agenst you. Immagine draging a fish through a swift current. You deal with the tention of your line, and the friction of the line through the guides. you also deal with friction when you use a drag.
Convergent evolution explains the similarity in body structure of the swordfish and dolphins, where two different organisms that are not closely related, independently evolved similar structures. Subjected to the similar aquatic environment and similar challenges, the swordfish and dolphins developed a similar body structure, a streamlined body (Figure 12; Baltimore, 2002). The streamlined body is the body structure that is broad in the middle and narrow at both ends. The development of the streamlined body is an advantageous structure to living in an aquatic environment. The streamlined body made it more efficient for locomotion, by reducing water resistance, thus increasing the efficiency of swimming for marine animals and for the vertebrates’
Our world is constantly changing as the society is often developing new technology. Ever since the technological breakthrough, technology has become a greater part of our daily life. From simple tasks of turning on the lights to more complex ones such as communicating with a robot on Mars, technology is shaping the modern society. As technology continues to advance, it is aiding us in every aspect of our lives, from diagnosing health problems, making our lives easier with the help of robots and providing us with better education, technology has made the world better. With technological innovations happening daily, technology is breaking barriers and changing the lives of countless people.
Artificial intelligence refers to the ability of machines to make decisions and perform duties on their own as if they were human beings. Primarily, artificial intelligence is associated with robots to form the term robotics. Robotics involves all the processes involved in the creation, management, development, use, and maintenance of robots. Robots came about as a result of technological development, and since their inception, they have affected various industries and sectors. Transportation is one of the areas that has been affected by artificial intelligence (AI), and there is still more promise of AI involvement in transportation. Overly, there are expectations for more positive impacts on transportation from robotics as compared to the
Ocean conservation, protecting and defending marine life is everyone’s concern because “oceans regulate our climate, produce half the oxygen we breathe, fuel the water cycle that produces rain and fresh water, sustain the livelihoods of millions, and provide nourishment for nearly 3 billion people” (“Oceans”). The number one resource is the ocean because of its mysterious benefits. About 70% of the world is made up of water; oceans are a significant part of that water. These large bodies of water are in great danger due to overfishing, global warming, and pollution. Oceans are being damaged more and more each day; the time is now for communities around the globe to take a stand before it is too late.
