This is sweet… Since 1992 nearly 30,000 plastic bath toys are floating on the Pacific Ocean after they were released into the water when a container was washed off a cargo ship. They are now expected to turn up on UK coasts in the next few days, for the joy of holiday-makers.
The ducks began life in a Chinese factory and were being shipped to the US from Hong Kong when three 40ft containers fell into the Pacific during a storm on January 29, 1992. Two thirds of them floated south through the tropics, landing months later on the shores of Indonesia, Australia and South America. But 10,000 headed north and by the end of the year were off Alaska and heading back westwards. It took three years for the ducks to circle east to Japan, past the original drop site and then back to Alaska on a current known as the North Pacific Gyre before continuing north towards the Arctic.
In 2000, eight years after their journey began, the ducks were reported in the North Atlantic and in 2003, they were expected to wash up on the east coast of America. By now the ducks had been bleached white by the sun and sea water. Sightings in the past two years have been scant, but oceanographers believe that their next port of call is southwest England, southern Ireland and western Scotland.
The landfalls have all been logged on a computer model called the Ocean Surface Currents Simulation, which is used to help fisheries and find people lost at sea. Two children’s books have been written about the saga and the ducks have become collector’s items, changing hands for £500.

where can I find that computer model called the Ocean Surface Currents Simulation? that would help a lot to get a better understanding on what the ducks actually gave travellled in time.
