Gakkel Ridge
The existence and approximate location of the Gakkel Ridge were predicted by Soviet polar explorer Yakov Yakovlevich Gakkel. It was confirmed on Soviet expeditions in the Arctic around 1950. The ridge is named after him. The name was recognized in April 1987 by SCUFN (under that body's old name, the Sub-Committee on Geographical Names and Nomenclature of Ocean Bottom Features).
