...its ability to detect enemy submarines for decades. The Navy’s low-frequency sonar system has been a topic of controversy among environmental advocates for years. This system, known as Surveillance Towed Array Sensor System Low Frequency Active (SURTASS LAF) allows the Navy to detect enemy submarines with enough time to react and defend themselves. During the course of developing and testing the SURTASS LFA system, environmental interest groups raised concerns that the system may cause harm to marine mammals. Whales use sound for communication, navigation, orientation, and in locating food. This is known as echolocation. The Navy’s mid-frequency sonar can cause whales to dive deeper into the ocean, or rise quickly. Like humans, whales can get the bends from these types of underwater movements. The loud noises created by the Navy’s sonar system are believed to interrupt their ability to communicate, navigate and look for food. These disruptions are believed to harm the whales physically and cause state of panic which often leads to strandings and collisions (Drumm). Active sonar utilizes sound in order to find objects in the water. A pulse is sent through the water, and then reflects off an object. This is called an echo. The receiver will convert the echoes into electrical signals which are digitally displayed on board the vessel. The high tech computers will be able to extract information such as distance and direction of the object. A major draw back of active sonar is that...

...Alex Espinosa Dr. Wilson MCWP 125 2/8/16 Why Naval Sonar Use Should Be More Highly Regulated Over recent years, military- derived sonar has been found to be linked with cetacean strandings. This and the general increase of noise in the ocean within the last century, which is known to have increased with the introduction of propeller ship engines (Jasny 12), has largely impacted the oceanic ecosystem. If such strong correlations have been scientifically determined, why has the United States Navy failed to adjust its practices in favor of saving marine organisms? How much evidence will suffice for the United States government to take necessary strides towards keeping our oceans safe? It is with this in mind that I claim that the U.S. Navy’s use of active sonar, whether it be mid or low frequency, needs to be more highly regulated. Therefore, government officials need to use their political power to support the marine species being affected by these anthropogenic noises. My first sub claim supporting my driving thesis will pertain to the negative impact sonar activity has on marine organisms. I will begin with the introduction of the importance of sound to the ocean’s mammals, the most prominent subjects of mid and low frequency sonar. This is an imperative aspect of this issue because the survival of every single one of these marine animals is based concretely in their specialized abilities to hear through the oceanic medium. With this I will present the scientifically supported...

According to the article, it states that “It is not a perfect imitation, but, astonishingly, recognizable.” This tells me that the whale is still practicing, and it is not perfect yet. This is the first demonstration of an orca imitate human words, which include the words “Amy” the trainer’s name, “Bye-Bye,” and “One-Two-Three.” The researchers are not expecting the words to be perfect, and the research was published in the journal Proceedings of the Royal Society B.

...Whale Rider was a movie produced in 2003, and it is about a girl named Paieka, or Pai. She is the granddaughter of Nanny Flowers and Koro. In the beginning of the movie, Koro has a good relationship with Pai. He brings her to school everyday by giving her a ride on his bike, and everything is good between them. Later on in the movie, Koro is worried about the rest of his people since they are drifting away from the traditions. People are smoking, the men are drinking and shooting pool, and the children do not take the ancestor celebrations seriously. Koro realizes that there is going to have to be a new leader, but his only option would be to have his granddaughter be leader, which goes against tradition. Pai is determined to prove to Koro that she could be a good leader even though she is female, and throughout the film, she tries to get Koro to acknowledge that she would be the best option for leader. Koro starts a school for the boys to find out who would be the best leader out of all of the boys in the village. He does numerous things with the boys to train them to be a chief, and Koro is planning to eventually pick the best leader out of everyone that he is teaching. Koro does not allow Pai to learn how to be chief in his training school since she isn’t a man. Pai learns how to stick fight from her uncle, and eventually defeats a boy in a stick fight. Koro saw this, and yelled at Pai for it, since that is not what women are supposed to do. Pai later wrote...

...Whale Rider In the novel The Whale Rider, by Witi Ihimaera, we learn about the Maori tribe from Whangara of New Zealand. They believe that the first person to come to their land was brought by a whale. They believe that this man was the Whale Rider. Being the Whale Rider is the passing of the tribal torch of leadership. When a girl is born, the first grandchild of that generation, her great-grandfather Koro is terribly disappointed. He doesn't acknowledge the possibility that she could be the one to take over leadership. However, even though Kahu is a girl, she was born with the gifts known to tribal heritage, such as being able to talk to the whales. Kahu is the eldest great-grandchild of Koro. Unfortunately, because Kahu is a female her great-grandfather has no interest in her because he is only focused on finding the next leader of the tribe. Kahu showers Koro with love, but does so continuously dismissing her abilities. Kori stays focused on continuing his classes for the males in the tribe and searches for “the one”. Spirited, young spirited Kahu, is also a member of the Maori tribe of Whangara but is not eligible for head role. Although being the great-grandchild of Koro means she should be able to overtake the leadership of the tribe, but unfortunately the tradition imagines a boy for this position. Therefore, she is not allowed to follow her determination or display her gifts. This situation leads to constant conflict with Koro who would surely have preferred a boy...

...BP.com vs. SeaWorld.com Credibility is defined as the degree to which someone or something is deemed trustworthy and believable. A company's credibility often determines success or failure. Efforts to build and sustain credibility must be ongoing and resolution must be immediate if that credibility is threatened. Comparing and contrasting BP.com and Seaworld.com both companies have faced a loss of credibility. Most public companies, at one time or another will have to deal with either negative or positive PR issues. The companies that have the negative PR must counter slanderous attacks immediately or they can potentially cause great harm to their company. Companies should perform in a safe and ethical manner at all times, but some choose not to. Most times special interest groups will object to what a company represents if the feel strongly enough towards an issue. When a company has to defend itself against strong beliefs that have been vocalized loudly in a public manner it must protect its own interests while retaining their profits and getting past the negative press. The easiest way for a company to communicate to the world is through its website. A company that wants to survive in this day and age has to have a website that a consumer can visit to obtain information and/or purchase products. A company gives itself a platform, via the website, to protect itself and rebut negative notations and address issues it feels it must address. A company...

The girls grandfather was joyous saying “we're having whale for dinner” and ran back to the house to fetch the girls father. Allison looked at the whale with delight when the wale spoke to her “please don't eat me for dinner” the whale said. When her grand father came back with Allison's dad, “the whale spoke again. “please don't eat me, if I could have your permission I would like to show Allison my home.” After deliberating the men agreed and Allison went into the ocean with the whale and they swam by the crabbie wabbies and visited with the fishie fishies, The whale and Allison had the time of their lives, the little girl didn't want to leave but the whale had made a promise and they returned from the ocean depths.

...DOES MILITARY SONAR KILL WHALES? In this report I’m going to argue against the concerns that a dolphin and whales conservation group have produced, and I will support my argument with evidences to prove my choice. I’m also going to use couple of charts and data to back up my answers. A dolphin and whales conservation group have produced artificial report. For instance they wrote ‘whenever there is a military sonar exercises, up to 200 whales die as a result of sonar damage’, which was exaggerated, 200 whales and dolphins died just once and that was on Manila Bay, Philippines in 2009. When we look at the data we can see the average number of cetacean stranded is 28.2, and ranges from 1-200 The reason I put the second graph is because it said on my sheet to plot a bar chart of the number of deaths at the time of naval exercises on the axes (3. 1) – hope it makes sense The secondary source from table one has a limited analysis; they have missed out so many years such as 2001, 2007 and they doubled up the year 2008, and it is in various locations. The second statement ‘Whales and dolphins are being damaged all around the world by military sonar exercises’ needs to be shown by having more locations that show that places with no sonar activity have no stranding. They have not told us how many military sonar exercises there were in one year or how many stranding there are when there are no military sonar exercises. They have also not told us how big the sonar exercises were so...

...Canaries of the Sea The white whales, or beluga, are residents of the arctic seas of the world. The common name is Russian, which comes from the adjective belii, meaning, “white”. Beluga whales have adapted to their life among sea ice, which is why they are all white in color and may grow up to eighteen feet in length (Haley, 1978). Belugas are gregarious and graceful and are enjoyed by everyone who meets them. Beluga whales are the only whales that can bend at the neck without moving their whole body. Different from other whales, they don’t have a dorsal fin but just a ridge on their back, which helps them trap the heat and stay warm in their icy Arctic surroundings. Belugas will migrate south to avoid getting trapped in the ice whenever the Arctic water freezes in the colder months. Belugas are mostly seen in large schools with a male leading the group. The schools may even get up to hundreds or thousands in numbers during migration (Tryckare, 1968)....

...Marine-mammal facilities are part of a billion-dollar industry built on the suffering of intelligent, social beings who are denied everything that is natural and important to them. Sadly, marine parks open their doors every summer to visitors who watch dolphins, beluga whales, and orcas perform their majestic tricks; they’re amazing, stunning, and very “enjoyable”… However, it might only seem fun to you, the marine animals who are performing the tricks themselves have to disagree, but, the question is, do you know the truth behind all this “joyful fun”? Marine animals in captivity is wrong. It needs to stop if it only means pain and abuse for our entertainments’ sake. I have many convincing reasons to support my opinion, including how captivity causes many health problems in marine mammals, these helpless creatures suffer from boredom, most of these poor innocent creatures face abusive treatment by their caretakers, thus shortening their life span by quite a lot, and marine mammals breed very poorly in captivity with very high infant death rates. So keep an open mind and choose to spend your money on family activities this summer that do not contribute to animal suffering. For starters, many wonder first where they all come from, or more importantly how they capture them. Dolphins are sometimes purposely injured by the capture teams to force the rest of their pod to stay behind into the trap, due to that dolphins never leave behind sick or injured friends or family members. But...

...Dolphin notes Wikipedia (various) They have well-developed hearing − their hearing, which is adapted for both air and water, is so well developed that some can survive even if they are blind Dolphins feed largely on fish and squid, but a few, like the killer whale, feed on large mammals, like seals. Male dolphins typically mate with multiple females every year, but females only mate every two to three years. Calves are typically born in the spring and summer months and females bear all the responsibility for raising them. Mothers of some species fast and nurse their young for a relatively long period of time. Dolphins produce a variety of vocalizations, usually in the form of clicks and whistles. Dolphins are descendants of land-dwelling mammals of the artiodactyl order (even-toed ungulates) J.G.

... The attributes that most primal religions and prehistoric cultures:myths, purification rites, and methods of control. All of these are explained in the Noss pdf, but not all attributes apply to the every primal religion. For example, a method of control is Shamanism. Shamanism is when spirits conjure in pr out of people by a person who is similar to spirit possession. Shamans, have a role of typical witch doctors, they could be a man or a women, Apache, Inuit and several other primal religions share this attribute. A myth is a traditional story that typically involves supernatural beings and events. Myths were a necessity, especially in primal groups, they were vital to portray the patterns of the group life. The Legend of Sedna, is a great example of an inuit myth; the story talks about a daughter named Sedna going away from her father to marry a handsome man, fulmar (bird man) and had a child with him. Her father has been looking for his daughter and once he found her, he put her in a kayak to take her back home. Fulmar found out and transformed into his bird state chasing after them. His father noticed asked his daughter for forgiveness and cut her fingers off so she couldn’t hold on to the kayak. Every finger he cut off turned into a sea animal. She then sank to the bottom, and now Inuit Shaman would travel down to the bottom of the sea to her kingdom to comb her hair because she can’t. One characteristic of primal religions that I find very intriguing is the purification...
