Influence of chronometer error uncertainties on the Longitude of Shackleton's vessel, Endurance
Abstract In 1915 while the Imperial Trans-Antarctic Expedition's vessel Endurance was icebound in the Weddell Sea, lunar occultation timings were carried out in order to rate the chronometers and thereby find longitude. The original observations have been re-analysed using modern lunar ephemeri...
