Using rubber ducks to map ocean currents

We found a rubber duck on the sands at Grune Point. It reminded me of the way that a spill of 28000 plastic bath toys into the Pacific Ocean in 1992 led to the mapping of ocean currents. See here for details. Our duck was not one of them - ours was from Poundland but looks like it's been in the sea a while. It is now adapting to its new home in Wigton!
