My initial reaction to the articles we read was of questioning towards the military. I am a firm believer in putting animals needs right next to ours, not after. When I learned how these animals, specifically the whales, dolphins, and porpoises, were being affected by the sonar, I was disturbed. My first thoughts were, "How could anyone in their right mind, one, hurt and kill helpless animals using this technology, and two, continue to use the technology that is killing these animals in the first place?" Now, I have never used sonar, nor have I ever fully understood the entire complexity of sonar, but even I know that if something is hurting/killing people, animals, or anything, that there should not be a legitimate reason to continue the practice! I do realize that the military, according to them, have perfectly legitimate reasons for using this sonar. But to me, all I'm interpreting is that they are aware that their practice is hurting animals, yet that is not an important enough problem for them to care. Now, I'm not saying that the military doesn't care about animals, but what I am saying is that there must be some way for us to put funds into research for something other than sonar. I did ask a couple questions about using infrared rays to detect the thermal energy of beings in the water, but I remembered that light doesn't travel well in water. However, if the right amount of light/heat is produced/emitted from the submarine, I feel as though this infrared detection could work. However, there would definitely be a large blind spot for the people in the submarine. So, I suggested that if we used low frequency sonar to detect objects farther out from the submarine, that would let us find enemy objects in the water, and the low frequency wouldn't disturb the marine life. I also had another idea. What if we researched the marine life in the Puget Sound (just as a trial for the experiment) and recorded their sound that alerted their other mammals to clear out? Think about it. If there was a certain clicking sound the dolphins used and is known to signal the phrase "need to scatter" or something similar, we could play this recording when the submarines detect the marine life. This way, the animals would hear "from one of their own" that they needed to evacuate. Then the submarines wouldn't have

about it, and liked the idea. I too liked submarines, there was something alluring about them, always mysterious and dangerous. One movie I had watched while at home in West New York on TV, which fascinated me was Ice Station Zebra. This was the days before movies like Red October, which would come much later. I found that submarine movie pretty cool, and always remembered it, so once my buddies had presented me with the idea of joining them in the Submarine Force I liked it. Plus never mind that by…

If the USS Indianapolis was equipped with sonar they could have the detected the submarine before they got torpedoed and could have evaded the the tragic event that took place. Lastly, one of the greatest miscalculations leading up to the tragic event was the navy…

that people, other than PETA, felt something was morally wrong. The Navy's Marine Mammal Program began in 1960 with two goals. First, the Navy wanted to study the sonar capabilities of dolphins and beluga whales to learn how to design better methods of detecting objects underwater, and to improve the speed of their boats and submarines by researching dolphins. In addition, the Navy also trained dolphins, beluga whales, sea lions and other marine mammals to perform different underwater…

(Submarine History). Submarines became possible all because of a man named William Bourne. He came up with the realization that if you, “…decrease the volume to make the boat heavier than the weight of the water it displaces, and it will sink. Make it lighter, by increasing the volume, and it will rise,” (Submarine History). Submarines have really helped scientific discoveries by increasing the underwater visibility…

Consequence of Sonar Use on Marine Life With the birth of marine warfare, the military struggled with seeing underneath the water. They needed a way to map the ocean to find old shipwrecks or to navigate around oceanic structures and a way to locate potential enemies. This search came with the answer of sonar. Sonar use has grown and developed over the years and the consequences are now being recognized. Whale and dolphin strandings have been recorded near Naval sites within hours of their sonar testing…

populations of whales are beginning to decline in areas of the ocean prone to noise pollution due to ships, submarines, and other military/government vesicles that make use of sonar exercises (Singla). Ships and other such vesicles that practice tactical solar exercises negatively impact the wellbeing of marine life, in this case whales, because they cannot withstand the extreme underwater noise from the sonar technologies and therefore beach themselves. This beaching is slowly decreasing the amount of whales…

World War II Sonar Inventions: What Is Ultrasound?

Ultrasound Back in World War II sonar equipment was used to help detect submarines, but with further discovery of this equipment, it was found that it would be beneficial for medical use. In 1947 Dussick discovered that this equipment, along with computer aid could help detect lesions and tumors within the skull. Dussick as well as Hueter, Bolt, and Ballantyne went even further to investigate the many benefits and uses, only to find that it would be too intricate for everyday clinical use. After…
