Mr Russell, of Batley, West Yorkshire, returned it to Bangor University
but was too late to get a five shillings - the equivalent of 25p in
today’s metric system - reward
The drifter disc had been released by John Harvey, now a retired
oceanographer, who was then working in the university's marine science
laboratory.
The disc was one of many released as part of the project and most never came back - this one being washed up more than 100 miles (161km) up the north west coast. Mr Russell said: "There must be something about the currents that bring things to this beach - I've previously found a meteorological balloon here." Mr Harvey said he found it "disturbing" that the plastic had lasted so long - a copper weight attached had eroded away.
"The research told us about the movement of seabed and sea-surface currents in the Irish Sea, and the results were published in a journal in 1968. We typically had return rates of about 34% for our drifters", he explained. The plastic has a very long life in the sea - it is in a good condition after 50 years, which is somewhat disturbing - unfortunately there is far too much plastic in the world's oceans generally."
