Whakaotihia te rerenga e whai ake nei: I muri i te wikitoria o Roald Amundsen i te Pou Tonga i te Hakihea 1911, i akiaki a Shackleton, i whai i tenei whakatutukitanga, kia whakaarohia ano e ia ana wawata pou. I whakapono ia kei reira tonu "tetahi kaupapa nui o nga haerenga Antarctic - te whakawhiti i te whenua o te Polar ki te Tonga mai i te moana ki te moana". I runga anō i tana rautaki i ngā mahere i hangaia i mua e te kaitirotiro o Rōpū Pōtiki, e William Spiers Bruce, i whakamahere a Shackleton kia eke tana rōpū matua ki te tonga rawa, ki te takutai o te Moana Weddell. Kātahi ka haere tana rōpū whakawhiti whenua ki te tonga ki te Pou, i mua i te haere tonu i te papa o te pou, ka heke iho mā te Beardmore Glacier (i whakaritea e Shackleton
i kitea i te tau 1909) ki te Great Ice Barrier. Ko te wahanga whakamutunga ka whakawhiti atu ki a rātou i te ārai ki McMurdo Sound i te takutai moana o Ross.
