The British National Antarctic Expedition, 1901–04, generally known as the "Discovery" Expedition, was the first official British exploration of the Antarctic regions since James Clark Ross's voyage sixty years earlier.
 Organized on a large scale under a joint committee of the Royal Society and the Royal Geographical Society (RGS), the new expedition carried out scientific research and geographical exploration in what was then largely an untouched continent.
 It launched the Antarctic careers of many who would become leading figures in the Heroic Age of Antarctic Exploration, including Robert Falcon Scott who led the expedition, Ernest Shackleton, Edward Wilson, Frank Wild, Tom Crean and William Lashly.
Shackleton is a 2001 British television film written and directed by Charles Sturridge and starring Kenneth Branagh as explorer Sir Ernest Shackleton.
 The film tells the true story of Shackleton's 1914 Antarctic expedition on the ship "Endurance".
 The cast includes Kevin McNally, Lorcan Cranitch, Embeth Davidtz, Danny Webb, Matt Day and Phoebe Nicholls (also the director's wife) as Lady Shackleton.
 It was filmed in the UK, Iceland and Greenland.
 The film used first-hand accounts by the men on the expedition to retell the story.
 Shackleton biographer Roland Huntford was a production advisor.
Shackleton Coast is that portion of the coast along the west side of the Ross Ice Shelf between Cape Selborne and Airdrop Peak at the east side of Beardmore Glacier in Antarctica.
 Named by New Zealand Antarctic Place-Names Committee (NZ-APC) in 1961 after Sir Ernest Shackleton.
 He accompanied Scott on the southern journey during the "Discovery" expedition (1901–04) and subsequently led three Antarctic expeditions.
 On the British Antarctic Expedition (1907–09), Shackleton discovered the area beyond Shackleton Inlet to the Beardmore Glacier, and was the first to find a practicable route to the South Pole.
 Lack of food stopped him 97 miles (180 km) from his goal.
Endurance was the three-masted barquentine in which Sir Ernest Shackleton sailed for the Antarctic on the 1914 Imperial Trans-Antarctic Expedition.
 She was launched in 1912 from Sandefjord in Norway and was crushed by ice, causing her to sink three years later in the Weddell Sea off Antarctica.
Mount Crean is one of the westernmost peaks in the dry valley region of South Victoria Land in Antarctica.
 It lies at , rises to 8630 ft , and is the highest summit in the Lashly Mountains.
 It is named after the Irish explorer Tom Crean, who was a member of both of Captain Scott's Antarctic expeditions (Discovery, 1901–04 and Terra Nova, 1910–13), and served as second officer on Sir Ernest Shackleton's Imperial Trans-Antarctic Expedition, 1914–17.
The Shackleton–Rowett Expedition, 1921–22, was the last Antarctic expedition led by Sir Ernest Shackleton.
 Proposed as an ambitious two-year programme of Antarctic exploration it was curtailed by the death of Shackleton and the inadequacies of the expedition's ship, "Quest".
 Under the command of Frank Wild several attempts were made to break through the Antarctic pack ice, but the expedition was never able to proceed further than longitude 20°E. On the crew's return to Cape Town to refit in preparation for the second term they were ordered home.
 The crew of the "Quest" comprised 24 members in all, but only 19 were on board for the start of the Antarctic portion (Hussey accompanied Shackleton's body when it was put on board a ship for England, and Eriksen, Mooney and Bee-Mason had left before the ship reached South Georgia).
 Gerald Lysaght, a yachtsman, accompanied the crew from Plymouth to Cape Verde.
Crean Glacier ( ) is a glacier 4 mi long, flowing northwest from Wilckens Peaks to the head of Antarctic Bay on the north coast of South Georgia.
 It was surveyed by the South Georgia Survey in the period 1951–57 and named by the UK Antarctic Place-Names Committee for Irishman Tom Crean, Second Officer of the "Endurance" during the British expedition under Ernest Shackleton, 1914–16.
 Crean accompanied Shackleton and Frank Worsley in the "James Caird" from Elephant Island to King Haakon Bay, South Georgia, and made the overland crossing with them to Stromness; this glacier lies on the route.
Major Robert Johnston, VC (County Donegal, 13 August 1872 – Kilkenny, County Kilkenny, 24 March 1950), was an Irish rugby union player and soldier.
 During the Second Boer War, Johnston was awarded the Victoria Cross while serving with the Imperial Light Horse.
 He played rugby for both Ireland and the British Lions.
 He is one of three Ireland rugby union internationals to have been awarded the Victoria Cross.
 The other two are Tom Crean, who also served with the Imperial Light Horse in the Second Boer War, and Frederick Harvey who served in the First World War.
 Johnston, Crean and Harvey all played club rugby for Wanderers.
 In 1896 Johnston and Crean were also members of the same British Lions squad that toured South Africa
Harbord Glacier ( ) is a glacier in Antarctica, flowing along the south side of Mount George Murray.
 It enters the Ross Sea south of Whitmer Peninsula where it forms Harbord Glacier Tongue.
 The name derives from the glacier tongue, which was named by Ernest Shackleton for A.E. Harbord, second officer of the "Nimrod" during the last year of the British Antarctic Expedition, 1907–09.
Shackleton: Death or Glory (also titled Chasing Shackleton) is a three-part documentary series following an attempt by adventurer Tim Jarvis to re-create the journey of Ernest Shackleton during his Imperial Trans-Antarctic Expedition of 1916.
 This two-part journey consisted of an open boat voyage from Elephant Island to South Georgia, and then an hike over the mountains of South Georgia to the whaling station at Stromness, where help could be sought.
