The story of the word

For Homer, Ὠκεανός was not a sea at all but a river running round the rim of the world, father of every spring and stream. Only later did the name attach to the open water beyond Gibraltar and then to the world's salt water in general. The compound is 19th-century, coined as sounding voyages began bringing back depth and temperature data nobody yet knew how to file.
