November 1909

Scott

Peary announced in November that an American expedition to the South Pole would be mounted within the next five years.


Amundsen

"View from the North Pole. A base map from 1910 looking down on the earth from the North Pole, to show how the meridians come to a point at the North Pole. Notice that if the 0 meridian were continued, it would unite with the meridian 180. The longitude circles of the Arctic Circle and Tropic of Cancer are shown, with the equator forming the circular outside edge of the map." [1]

At some point after attending a lecture at the Royal Geographical Society in London given in November 1909 by A.R. Hinks, lecturer on Surveying and Cartography at Cambridge, Amundsen decided that he would adopt Hinks' theory on the subject of determining position near the Poles.

Hinks reasoned that since, as one approaches the geographical pole the meridians of longitude converge and its degrees become ever smaller, this measure eventually becomes meaningless, and that the extra effort in obtaining a measurement of longitude can be saved, focusing instead on latitude alone.

November 1909

Scott

"The South Polar Expedition: Capt. Scott and his exploration ship 'Terra Nova'" [1]

Scott had spent the past few months trying to stump up money, with tedious result. "£40 to-day," he wrote, "nothing from Wales -- made an agreement with Bowring to pay only £5,000 on the eighth, don't know how I shall manage even that." [2]

This £5,000 was the first of a £12,500 payment for a ship. As the Discovery, which had been sold upon return from the Antarctic, was not available, nor either Morning or Nimrod, this was to be the Terra Nova.
