Very sad pictures on the late news tonight . There are reports of other strandings along the Cornish coast , another theory mentioned was the posiblity of naval sonar confusing the dolphins.
Lets hope its a one off .

The Royal Navy WAS carrying out a sonar survey at the time.

I have always turned my echosounder off if there are dolphins around - how many people bother I wonder? I bet my Raymarine has a bit less power though........

Happens all the time in the Tasmania Strait. Aussie Navy have been blamed but no facts so far.

Turning off your echo sounder only turns off the screen the transmitter still sends pulses as long as you battery switch is on. To be able to switch the transmitter off you have to fit a switch between the battery and unit. I used to think I was switching mine off by turning the screen off until a friend was testing a pod (a unit that picks up and records cetacean activity in an area when left on the sea floor) to see how our boat registered for sound. Even though I thought the echo sounder was off it still registered.

There is switch on my DSM300 module that I flip.
I am dubious about sonar hurting them as Dolphins seem to be quite at home in places like Gib harbour etc where there are loads of ship movements - they wouldn't be there if they didn't like it BUT maybe if they are already confused or in danger they don't help.
