Do the particles stay close to the surface and are only lethal if you are close enough to the strike? Moreover, if the vessel does not have a metal hull and is not earthed to the water, the danger is multiplied considerably. Moreover, the proper calculation involves integrating $\rho/r^2$, which diverges unless the lightning strikes an extended area. Still, I've been on boats in Fl trying to out run the storms which you can see coming miles off on the open ocean, but once you finally get to the shore and head down the canals the Manatee warning signs say 5 mph.

The good news … Sign up for EXPRESS SCIENCE NEWS delivery: This new perspective on lightning is possible thanks to two satellite-based detectors: the Optical Transient Detector (OTD) and the Lightning Imaging Sensor (LIS). According to a new NASA map of global lightning rates, such strikes over open ocean waters are rare. Apparently the surface water does not heat up enough to cause the positive charge needed for lightning to occur. Despite water being a good electrical conductor, lightning doesn’t travel further in … The flow of warm ocean currents past drier ... it may separate into multiple bidirectional leaders.

So what happens to fish when lightning strikes? The charge from a lightning strike is dissipated within about 8 feet … How far the charge travels depends on the intensity of the lightning, topography of the water, salinity and temperature. Generally, lightning can travel for 20 feet through water before dissipating. water is a conductor, so do the fish die? Menu Sign Up.

(Sault Ste. Lightning strikes strike near water because water is a good conductor of electricity. However it does not significantly change the danger of electric shock, burns and sound pressure waves which are mostly the same for salt or fresh water lightning strikes if you're within the energy dispersal area. What to do in a Lightning Storm on a Boat.
