Two articles appeared last week in Irish newspapers about a drift bottle from a study that Dr. Edward Monahan established when teaching in what is now the National University of Ireland, Galway, from 1976 to 1986. Links to these articles are appended below. We will not know the particulars of this ballasted bottle’s drift until the unique number on the card in this bottle is distinguished – a hard job to do. But the working hypothesis is that this drift-bottle, found recently on the sea-floor near Murmansk, Russia, was released off the west coast of Ireland during the 1980s!
