[Coral-List] Air Guns on Social Media

It has been pointed out that there is little knowledge on the effects of 
sound on turtles. As most everyone involved with the ocean knows mature 
turtles are really tough critters. I well remember the dead land turtle 
we used in my physiology class lab years ago. It was kept in a fridge 
for weeks. Each week we did experiments and the heart was still beating 
when we applied various chemicals to stimulate beats. Once when I was 
young I butchered a green turtle. I will never do that again. The heart 
kept beating. And yes before refrigeration turtles were a main source of 
food. So when we applied for a permit to core the Florida Middle Grounds 
with our diver operated hydraulic coring apparatus there were folks in 
the Sanctuary that resisted on the grounds the sound might harm turtles. 
I simply pointed out that it was the same device they used to install 
buoys on coral reefs for divers. Problem solved. Gene PS: I notice the 
social media segment of my earlier posting has not been addressed.
