Rutgers Blasting off of Long Beach Island

[Inishmore3]

Please read the information below. Please write to the Rutgers President. Please write to the Governor of New Jersey. Please write to the senators of New Jersey. We need to stop this. Lets join together.


Stop New Jersey’s Fishing Grounds from Getting Blasted!!! A proposed Rutgers University Seismic Study will sweep the ocean just off Long Beach Island. With blasts 250 decibels (100,000 times louder than a jet at take-off) every 5 seconds, 24 hours a day for 30 days fishing will be affected. Studies show that fish can be injured or scared off by seismic blasts. The study area and the affected fishing grounds: all inshore and offshore wrecks, the Fingers, Barnegat Ridge, the Lillian Wreck, 28 Mile Wreck and over 230 square miles of ocean will be directly impacted. The LOUD blasts will travel far beyond study impact zone. Everyone from Surfcasters to Back Bay Anglers to Offshore Fishermen will be impacted!

YOU CAN HELP!!! CONTACT RUTGERS PRESIDENT ROBERT BARCHI: 848-932-7454 and email the President today http://president.rutgers.edu/contact...esident-barchi

TELL HIM TO STOP THIS SUMMER’S STUDY!!! For more information: CleanOceanAction.org

I'm thinking your math is way off with the decibels

[NoLimit]

250 db is the sound of loud fireworks.

According to OSHA Decibel Charts a Jet Engine at 100 feet is 140 dB and death of Hearing Tissue occurs at 180 dB's.

OSHA/NIOSH Daily Permissible Noise Level Exposure at 112-115 dB is 15 minutes per day.

Decibel level in water has a different measurement than in air! “The decibel is a relative unit of measure, not an absolute one. Confusion arises because relative intensities in water are referenced to 1 microPascal (µPa) whereas sound waves in air are referenced to 20 microPascals (µPa). The intensity of a sound wave depends not only on the pressure of the wave, but also on the density and sound speed of the medium through which the sound is traveling. Therefore, relative sound intensities given in dB in water are not the same as relative sound intensities given in dB in air.”

I'm all for research but this is being done in the middle of the fishing season ??

Sounds like you are very informed. I would like to ask a question. Does sound travel further in water? Does water magnify sound waves?
