Heirtzler Fracture Zone

The Heirtzler Fracture Zone (-63.5°N, 162.5°W) is an undersea fracture zone located south of New Zealand near Antarctica.

The feature was named for James R. Heirtzler, a geophysicist who was a pioneer in geomagnetics studies. The name was proposed by the Lamont–Doherty Geological Observatory (now the Lamont–Doherty Earth Observatory), and was approved by the Advisory Committee on Undersea Features in 1993.
