The expedition ship RRS Discovery in the Antarctic alongside the Great Ice Barrier, now known as the Ross Ice Shelf. The Discovery Expedition of 1901–1904, known officially as the British National Antarctic Expedition, was the first official British exploration of the Antarctic regions since the voyage of James Clark Ross sixty years earlier (1839–1843).
The first clock known to strike regularly on the hour, a clock with a verge and foliot mechanism, is recorded in Milan in 1336. [96] By 1341, clocks driven by weights were familiar enough to be able to be adapted for grain mills, [97] and by 1344 the clock in London's Old St Paul's Cathedral had been replaced by one with an escapement.

The Board of Longitude had asked Kendall to copy and develop John Harrison's fourth model of a clock useful for navigation at sea. The first model finished by Kendall in 1769 was an accurate copy of H4, cost £450, and is known today as K1. Although constructed like a watch, the chronometer had a diameter of 13 cm and weighed 1.45 kg.
National Antarctic Expedition (Discovery Expedition) 1901–1904 Robert Falcon Scott: In 1905 Discovery was bought by the Hudson's Bay Company, and used as a cargo vessel until 1911. [10] After some years' inactivity in London, Discovery was used as a supply ship during the First World War. [11]
The expedition divided itself between the ship and the shore, with Discovery being used for accommodation and the prefabricated hut, intended to be the expedition's winter living quarters, was used as a laboratory. Although surrounded by ice the ship was not yet frozen in.
It was erected in 1911 by the British Antarctic Expedition of 1910–1913 (also known as the Terra Nova Expedition) led by Robert Falcon Scott. In selecting a base of operations for the 1910–1913 Expedition, Scott rejected the notion of reoccupying the hut he had built by McMurdo Sound during the Discovery Expedition of 1901–1904.

Another significant find of the expedition was the discovery of a "living fossil", the monoplacophoran Neopilina galathea, dredged from the bottom of the Mexican Gulf. [ 3 ] Already in the 1930s, American scientist began to use seismic measuring methods in flat waters and during the war, physicist Maurice Ewing carried the first seismic ...
