Question: What country claims ownership of the island the crew sheltered on after their ship's hull was crushed? Passage:He led the 1901-1904 Swedish Antarctic Expedition, aboard the ship Antarctic. The expedition visited the Falkland Islands before the ship, commanded by seasoned Antarctic sailor Carl Anton Larsen, dropped Nordenskjöld's party off at Snow Hill Island, a small island off the coast of the Antarctic Peninsula. Nordenskiöld overwintered at Snow Hill Island, while Antarctic returned to the Falklands. The following summer Larsen brought her south, intending to retrieve the Nordenskiöld party, but she became trapped in ice which eventually crushed her hull, forcing Larsen and his crew to overwinter in a hastily constructed shelter on Paulet Island. Larsen and Nordenskjöld finally rendezvoused at their fall-back rescue hut at Hope Bay in late 1903, where they were picked up by the Argentine Navy corvette ARA Uruguay (commanded by Julián Irízar), which had been dispatched when Antarctic had failed to make her appointed return to South America the previous year. Despite its end and the great hardships endured, the expedition was considered a scientific success, with the parties having explored much of the eastern coast of Graham Land, including Cape Longing, James Ross Island, the Joinville Island group, and the Palmer Archipelago. The expedition, which also recovered valuable geological samples and samples of marine animals, earned Nordenskjöld lasting fame at home, but its huge cost left him greatly in debt.

Question: How long did Grafton Elliot Smith know Donald Alexander Mackenzie at the time he wrote the foreword of Ancient Man in Britain? Passage:In 1922, Mackenzie published Ancient Man in Britain, a work covering the history of Britain from Upper Paleolithic times, from a strong ethnological basis. The foreword of the book was written by Grafton Elliot Smith. The work covers the earliest settlement of Britain by the first modern humans from around 35,000 years ago during the Aurignacian (pp. 19–27). In the book, Mackenzie maintains that the Caucasoid Cro-Magnons who settled in Britain were dark haired and dark eyed, racially akin to the French Basques, Iberians and Berbers of North Africa (p. 25), who he theorised were one of the earliest representatives of the Mediterranean race. This indigenous proto-Mediterranean racial stock was later invaded by another "variety of the Mediterranean race" who initiated the Solutrean culture around 20,000 years ago (p. 50). According to Mackenzie, the Aurignacian and Solutrean peoples of Britain traded in shells with Cro-Magnons of France. They later intermingled with later arriving Caucasoid racial types, including the proto-Alpines (Furfooz race), who were brachycelphalic (broad-skulled) and a Lappid race, who had minor Eskimo phenotypic traits. Mackenzie also believed that there was a highly depigmentated racial type in small numbers in Britain during the Magdalenian, perhaps who were also blonde, who intermingled with the "dark Iberians" (p. 60). During the Neolithic, Mackenzie believed that the predominant racial type of Britain continued to be Mediterranoid: "The carriers of Neolithic culture were in the main Iberians of Mediterranean racial type" (p. 126) who traded in pearls and ores. Regarding Bronze Age Britain, Mackenzie devoted several chapters supporting his theory that traders and "prospectors" (miners) arrived in Britain c. 2500 BC, originally from the Eastern Mediterranean (pp. 98–101). This theory was initially developed by Harold Peake, who coined the term "Prospector Theory". In the scientific literature of Carleton S. Coon (1939), the theory was revived, and the Mediterraneans who colonised Britain during the late Neolithic or Bronze Age were associated with the Medway megaliths (or long-barrow Megalithic culture). Joseph Deniker earlier called these colonists "Atlanto-Mediterranean". Mackenzie believed that these Mediterraneans who colonised parts of Britain survived well into later historic periods (p. 118) and that the Mediterranean race in general was the bulk racial stock of Britain from Paleolithic through to the Neolithic and to more recent periods. They had black or brown hair, and swarthy skin "like those of the Southern Italians" (p. 126) and have survived in numerous pockets of Britain to the modern day (p. 139) despite that the later Anglo-Saxon and Norse settlement, who were fairer in appearance, Mackenzie believed their genetic input or admixture was very limited but that they subjugated the British imposing a new civilization and culture (p. 227).
