Voyage of Discovery

I saw this on BBC (TV) news last week, but spied CNN's version of the story this morning.

An armada of small, faded yellow toy ducks is expected to make landfall in Britain within weeks at the end of an epic 11-year voyage from the Pacific Ocean. They are the survivors of a consignment of 29,000 bath toys washed overboard from a container ship in 1992 that have since floated across the ocean, round the United States, through the Arctic and past Greenland....

The report I saw said that oceanographers were very keen to find the ducks as they were following Arctic currents that were usually difficult to monitor. They had provided useful data on the flow and patterns of these currents.

I assume they were all Drakes.
