Description
A 1912 map of the Indian Ocean in Tiefenkarten der Ozeane mit Erlauterungenby Max Groll. Note the light-colored (shallower) area between Australia andAntarctica, an early indication of the continuity of the oceanic ridge systemin the South Indian and South Pacific Oceans. Amazingly, a feature as large asNinety East Ridge had yet to be discovered. Plate II, Indian Ocean. (Image credit: NOAA Central Library Historical Collection)
