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

Scientific Hypothesis Experiement: Sonar testing has detrimental make on devil dog life Surveillance Towed get down Sensor System (SURTASS) Low oftenness Active (LFA) echo give wayer is the U.S. Navys newest must- film defense technology. The Navy claims that LFA echo sounder go give away be able to detect todays quieter submarines so reliably that it plans to moorage LFA routinely throughout most of the worlds oceans. However, LFA sonar whitethorn misuse whales and other marine mammals. This sonar will generate headliner of the loudest sounds 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, spread overing, feeding, and communication. A sound quaver can cause material that resonates in its frequency to vibrate, shatter, shear, or tear . somewhat air spaces in mammals and fish may controvert 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 due 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 aft(prenominal) a Navy exercise in which mid-frequency active sonars were used. go beaked whale mass strandings have o ccurred in the past, this was the premier(p! renominal) metre that a qualified scientist was on hand to pick up the arrogate samples from fresh carcasses to determine cause of death. The most late(a) 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...
