To reduce errors in geomagnetic measurements, the research vessel Carnegie was specially constructed of non-magnetic materials. While refueling in Apia Harbor, Samoa, November 29, 1929, an explosion occurred, destroying the ship and taking the lives of Captain J. P. Ault and the ship's cabin boy. In her 20 years, Carnegie cruised 342,681 miles of the world's oceans.
