His later chronicle of the expedition was critical of aspects of Borchgrevink's leadership, but defended the expedition's scientific achievements. In 1901, Bernacchi would return to Antarctica as a physicist on Scott's "Discovery" expedition. Another of Borchgrevink's men who later served Scott's expedition, as commander of the relief ship , was William Colbeck, who held a lieutenant's commission in the Royal Naval Reserve. In preparation for the Southern Cross Expedition, Colbeck had taken a course in magnetism at Kew Observatory.
