A short review on sonar testing and it's detrimental effects on marine life -- somewhat opinionated.

Scientific Hypothesis Experiement: Sonar testing has detrimental do on devil dog life Surveillance Towed arrange Sensor System (SURTASS) Low oftenness Active (LFA) asdic is the U.S. Navys newest must- film defense technology. The Navy claims that LFA asdic go bring out be able to detect todays quieter submarines so reliably that it plans to fleck LFA routinely throughout most of the worlds oceans. However, LFA sonar may misemploy whales and other marine mammals. This sonar will generate fl are of the loudest ponderouss that human beings throw out make in the ocean. Worse, because they are low-frequency in nature, these sounds can travel for hundreds of miles, effectively ensonifying thousands of cubic miles of ocean. LFA may damage or destroy marine mammal hearing, as nearly as disrupt calving, extending, feeding, and communication. A sound thrill can cause material that resonates in its frequency to vibrate, shatter, shear, or tear. somewhat air spaces in ma mmals and fish may pit to LFA sonar in this manner. All of this is too mellowed a equipment casualty to pay for questionable security against the latest breed of submarines. It is exactly nessecary to perform anymore experiements to prove the idea that sonar waves have adverse affects on marine life out-of-pocket to the high number of beached mammals on our shores. In March 2000, a can stranding of beaked whales, minke whales, and one dolphin occurred off the Bahamas by and by a Navy exercise in which mid-frequency active sonars were used. man beaked whale mass strandings have occurred in the past, this was the maiden metre that a qualified scientist was on hand to suck the arrogate samples from fresh carcasses to determine cause of death. The most fresh results of the on-going investigation into this incident indicate that these whales died from the impacts of a loud sound playing on their air...
