The Cornish beaches where Lego keeps washing up
> No-one knows exactly what happened next, or even what was in the other 61 containers,<p>WHAT?<p>I imagined every container to have tracking and identification numbers so the owners could know roughly where it is at all times; and so that various government agencies could prevent import of things not allowed in their countries.  A quote a bit later on kind of supports that.<p>> She says the ship's manifest - a detailed list of everything in the containers - shows a whole range of Lego items, not all sea-themed. After all this time "it's the same old things that keep coming in with the tide", particularly after a bad storm.<p>I'm surprised about how many containers are lost.<p>> About 120m containers carried on world's oceans in 2013<p>> 2011 survey by World Shipping Council estimated an average of 675 containers lost at sea each year between 2008-10<p>> 2014 survey says average annual loss between 2011-13 was approximately 2,683 containers<p>2,500 containers out of 120m is a small number, but still.  How would you design a pinger suitable for shipping containers so that they could be located after being dropped overboard?<p><i></i>EDIT<i></i> I should have said that this pinger thing is just a thought experiment.  Obviously most containers are no lost, and most of the ones that are are not toxic / valuable enough to bother with.  (But thanks to the posters below)
