South Magnetic Pole
Despite the unexplained disappearance of many of Hansen's notes, Hugh Robert Mill described the expedition as "interesting as a dashing piece of scientific work". The meteorological and magnetic conditions of Victoria Land had been recorded for a full year; the location of the South Magnetic Pole had been calculated (though not visited); samples of the continent's natural fauna and flora, and of its geology, had been collected. Borchgrevink also claimed the discovery of new insect and shallow-water fauna species, proving "bi-polarity" (existence of species in proximity to the North and South poles).
