I have attached an updated Google Earth file which shows that the IRL unusual mortality event in Manatees, Dolphins & Pelicans is highly correlated with the following items:1) Port Canaveral & the Barge Canal East/West2) Barge routes to the South and North3) Barge Ports and Marinas4) Areas of Radars/AntennasThe most common form of death in humans around marinas is Electric Shock DrowningThese match the symptoms that the scientist is reporting, ie. “Shock, sudden drowning” – I know, you think eating grass can drown you…http://www.orlandosentinel.com/news/environment/os-manatee-deaths-resume-indian-river-20160712-story.htmlThe ICCP corrosion protection on many cargo barges, cruise & warships puts up to 500-1500 amps of 50-100V DC current into the surrounding water.AC is worse than DC but those large vessels are putting LOTS of DC current into the water. AC current can leak from regular marinas/boats plugged into 110V AC power
“Why fresh water and not salt? Salt-water is anywhere from 50 to 1,000 times more conductive than fresh water. The conductivity of the human body when wet lies between the two, but is much closer to saltwater than fresh. In saltwater, the human body only slows electricity down, so most of it will go around a swimmer on its way back to ground unless the swimmer grabs hold of something — like a propeller or a swim ladder — that’s electrified. In fresh water, the current gets “stuck” trying to return to its source and generates voltage gradients that will take a shortcut through the human body. A voltage gradient of just 2 volts AC per foot in fresh water can deliver sufficient current to kill a swimmer who bridges it. Many areas on watersheds and rivers may be salty, brackish, or fresh depending upon rainfall or tidal movements. If you boat in these areas, treat the water as if it were fresh just to be on the safe side.
Why alternating current and not direct current (DC)? The cycling nature of alternating current disrupts the tiny electrical signals used by our nerves and muscles far more than the straight flow of electrons in direct current. “It would require about 6 to 8 volts DC per foot to be dangerous,” Rifkin said, or three to four times as much voltage gradient as with AC. “Regardless of the type of voltage, the larger the voltage, the larger the gradient over the same distance.” There have been no recorded ESD fatalities from 12-volt DC even in fresh water because there is less chance of the higher voltage gradient necessary developing with DC’s lower voltages.”The fish are dying when the salinity drops during rain events over the lagoon. Change of shock is highest when salinity drops.
