Celebes Sea
Celebes Sea The Celebes Sea is a piece of an ancient ocean basin that formed 42 million years ago in a locale removed from any landmass.

By 10 million years ago the Celebes Sea was inundated with continental debris, including coal, which was shed from a growing young mountain on Borneo and the basin had docked against Eurasia. The border between the Celebes and the Sulu Sea is at the Sibutu-Basilan Ridge. Strong ocean currents, deep sea trenches and seamounts, combined with active volcanic islands, result in complex oceanographic features. On the North.
