Question: McCarthy Island as named after Timothy McCarthy, who sailed on the "Endurance" during an expedition for the Antarctic under which captain?
Context: Endurance is an impact crater lying situated within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars.  This crater was visited by the "Opportunity" rover from May until December 2004.  Mission scientists named the crater after the ship "Endurance" that sailed to the Antarctic through the Weddell Sea during the ill-fated 1914-1917 Imperial Trans-Antarctic Expedition, considered to be the last expedition of the Heroic Age of Antarctic Exploration organized by Ernest Shackleton. The Havre Mountains ( ) are a large group of mountains forming the northwestern extremity of Alexander Island, Antarctica, extending 20 nmi in an east–west direction between Cape Vostok and the Russian Gap.  They were first seen in 1821 by a Russian expedition under Fabian Gottlieb von Bellingshausen and re-sighted by the Belgian Antarctic Expedition, 1897–99.  They were roughly charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, who named them for Le Havre, the French port from which the "Pourquol Pas? " sailed in 1908.  The mountains were mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960. Mullins Valley ( ) is a four mile long valley located at 5,400 ft elevation in the McMurdo Dry Valleys.  It is one of the few dry valleys in the world to contain rock glaciers.  US Antarctic Program (USAP) research has dated the subsurface ice in Mullins Valley at 4 million years old making it among the oldest ice on earth.  United States Antarctic Program (USAP) research has also shown the rock glaciers in the valley to be analogous to the Arsia Mons region on Mars.  Named for Jerry L. Mullins, Physical Scientist, Director, Polar Programs, Antarctic and Arctic Program for United States Geological Survey (USGS), National Science Foundation Antarctic geophysical research, and U.S Scientific Committee (SCAR) delegate to SCAR SCAGI committee.  Appointed by the National Academy of Sciences, Polar Research Board.  His was responsible for Antarctic field research in the Transantarctic Mountains, McMurdo Dry Valleys, Shackleton Mountains, Beardmore Mountains, Antarctic Peninsula, Mount Siple, Amundsen-Scott South Pole station and at deep field research locations in West Antarctica.  His program conducted research in the disciplines of global positioning systems, geodesy, crustal motion, glacial geophysics, airborne geospatial systems, airborne geophysics, seismology, light radar (lidar), topographic mapping and he managed the USGS South Pole winter-over program from 1989 to 1994.  He was appointed by the National Academy of Sciences, Polar Research Board as a US delegate to the Scientific Committee on Antarctic Research Geosciences Standing Scientific Group from 1995–July 2012 and was appointed as a member of the Advisory Committee on Antarctic Names in 1994.  Mullins Valley appears in the Antarctic research literature, on the maps from the British expedition of Captain Scott and in aerial photographs from the United States expedition Operation Highjump by Admiral Byrd.  Mullins Valley, Mullins Lake, Mullins Glacier, and Mullins Geodetic Station, Antarctica are named for United States polar explorer and researcher Jerry L. Mullins. McCarthy Island is an island 2 nmi long, lying just northeast of Fold Island, off the coast of Kemp Land, Antarctica.  It was mapped as part of Fold Island (Foldoya) by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, but was identified as a separate island by an Australian National Antarctic Research Expeditions (ANARE) geological party in 1961.  The island was named by the Antarctic Names Committee of Australia for W.R. McCarthy, an Australian petrologist who described several hundred specimens from Antarctica collected by ANARE geologists. James "Scotty" Paton (1869–1917 or 18) was a Scots-born seaman who sailed to the Antarctic in several major expeditions between 1902 and 1917.  His first venture was from 1902 to 1904 as a crewman of "Captain William Colbeck"'s SY Morning.  This expedition consisted of two voyages and was sent as a relief ship for the Captain Scott's Discovery Expedition.  During the first voyage the ship was briefly stalled in the ice between Cape Bird and Beaufort Island.  Scotty Paton took the opportunity to leave ship and jump floes a distance of one mile to 'land' of Beaufort Island, the first man to do so.  This accomplishment was received with a reprimand.  In 1907–09 he was a crew member of Sir Ernest Shackleton's Nimrod Expedition during each of "Nimrod's" two southern voyages.  From 1910 to 1913 he was a seaman aboard Captain Scott's "Terra Nova" during her two voyages between New Zealand and Cape Evans, in support of Scott's ill-fated expedition.  In 1914 he joined the Ross Sea party section of Shackleton's Imperial Trans-Antarctic Expedition as boatswain on the "Aurora".  He was aboard ship on 7 May 1915 when "Aurora" was torn from her Cape Evans moorings, drifting in the pack for nine months before limping back to New Zealand.  Paton's last Antarctic voyage was with "Aurora" on the mission to relieve the stranded Ross Sea party in January 1917. Mount McCarthy is a peak, 2,865 m high, standing 1 nmi northwest of Schofield Peak, in the Barker Range, Victoria Land, Antarctica.  It was named by the New Zealand Federated Mountain Clubs Antarctic Expedition (NZFMCAE), 1962–63, after Mortimer McCarthy, a member of the crew of the "Terra Nova" of the British Antarctic Expedition, 1910–13.  McCarthy was a guest of the U.S. Navy during the 1962–63 season when he revisited McMurdo Sound with two other Scott veterans. Français Glacier ( ) is a glacier 4 nmi wide and 12 nmi long, flowing north-northeast from the continental ice to the Antarctic coast close west of Ravin Bay.  Though no glaciers were noted on Captain Jules Dumont d'Urville's chart of this coast, the close correlation of his "Baie des Ravins" feature and narrative description with the indentation of the coast near the mouth of this glacier suggests first sighting of this feature by the French Antarctic Expedition, 1837–40.  During December 1912 members of the Main Base Party of the Australasian Antarctic Expedition (AAE) camped on the upland slopes close east of the glacier, but no reference was made to the glacier in the AAE reports, though a clear view and unpublished sketch were obtained of the distant coast to the northwest.  It was delineated from air photos taken by U.S. Navy Operation Highjump, 1946–47.  The French Antarctic Expedition under Mario Marret, 1952–53, sledged west on the sea ice to the ice cliffs close east of the glacier.  It was named after the "Français", the expedition ship of the French Antarctic Expedition, 1903–05, under Dr. Jean-Baptiste Charcot. Norman Champion Toutcher (1884–1924) was a sailor, mainly known for his time as Chief Officer of the SY "Aurora" during the 1911–1914 Australasian Antarctic Expedition, under Captain John King Davis.  Toutcher joined the expedition in Cardiff, and sailed to Australia, where the expedition proper started.  He accompanied the "Aurora" on its first Antarctic voyage—south from Hobart to Macquarie Island, on to the Antarctic mainland to drop off the land parties, and back to Australia.  However, Davis thought Toutcher a "hopeless fool", and he was replaced by Frank D. Fletcher on 12 March 1912, when the "Aurora" arrived back in Hobart. McCarthy Island is an island, 1 nmi long, lying in the entrance to King Haakon Bay on the south side of South Georgia.  It was surveyed by the South Georgia Survey in the period 1951–57, and was named by the UK Antarctic Place-Names Committee after Timothy McCarthy, a seaman on the "Endurance" during the British expedition under Ernest Shackleton, 1914–16.  McCarthy accompanied Shackleton in the "James Caird" from Elephant Island to King Haakon Bay. 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.
