The 1916 publication re-ignited interest in the flyaway islands, and explorer Sir Ernest Shackleton, when planning the Shackleton–Rowett Expedition of 1921–1922, proclaimed as one of his goals the rediscovery of Tuanaki. The explorer died in Antarctic waters before he was able to mount a serious search for the vanished archipelago.{{cite web |url=https://news.google.com/newspapers?id=FrFXAAAAIBAJ&sjid=uPMDAAAAIBAJ&pg=6442,621950 |title=Shackleton, Antarctic Explorer, is Dead |work=The (Spokane) Spokesman-Review |date=February 3, 1922 |access-date=17 March 2012}}
