It's not known. There are several hypotheses. Among them are:

* Because it was inhospitable for environmental reasons or because of nearby savages. * Because a certain kind of algae grows in it. * Because it is further north than the Mediterranean and directions were once designated by colors. North was black. * In naval science it is thought to be because of a microbe that populates a deep layer of the water. * Etc.
