Usually pop-over text would have some extra tid-bit: like him having calculated how many words can fit over the ocean along the way, he might say how many Oxford dictionaries or Ulysses that is, though it's obviously too much for this particular example. Maybe a rate at which we'd get another Ulysses in the ocean would make sense: every 45 minutes there'd be another Ulysses worth of words in the ocean :)
