Patricia Margaret Millar Date ii Abstract Photographers made a major contribution to the recording of the Heroic Era of Antarctic exploration. By far the best known photographers were the professionals, Herbert Ponting and Frank Hurley, hired to photograph British and Australasian expeditions. But a great number of photographs were also taken on Belgian, German, Swedish, French, Norwegian and Japanese expeditions. These were taken by amateurs, sometimes designated official photographers, often scientists recording their research. Apart from a few Pole-reaching images from the Norwegian expedition, these lesser known expedition photographers and their work seldom feature in the scholarly literature on the Heroic Era, but they, too, have their importance. They played a vital role in the growing understanding and advancement of Antarctic science; they provided visual evidence of their nation’s determination to penetrate the polar unknown; and they played a formative role in public perceptions of Antarctic geopolitics. -

Chapter 4 Tectonic Reconstructions of the Southernmost Andes and the Scotia Sea During the Opening of the Drake Passage
123 Chapter 4 Tectonic reconstructions of the Southernmost Andes and the Scotia Sea during the opening of the Drake Passage Graeme Eagles Alfred Wegener Institute, Helmholtz Centre for Marine and Polar Research, Bre- merhaven, Germany e-mail: [email protected] Abstract Study of the tectonic development of the Scotia Sea region started with basic lithological and structural studies of outcrop geology in Tierra del Fuego and the Antarctic Peninsula. To 19th and early 20th cen- tury geologists, the results of these studies suggested the presence of a submerged orocline running around the margins of the Scotia Sea. Subse- quent increases in detailed knowledge about the fragmentary outcrop ge- ology from islands distributed around the margins of the Scotia Sea, and later their interpretation in light of the plate tectonic paradigm, led to large modifications in the hypothesis such that by the present day the concept of oroclinal bending in the region persists only in vestigial form. Of the early comparative lithostratigraphic work in the region, only the likenesses be- tween Jurassic—Cretaceous basin floor and fill sequences in South Geor- gia and Tierra del Fuego are regarded as strong enough to be useful in plate kinematic reconstruction by permitting the interpretation of those re- gions’ contiguity in mid-Mesozoic times. Marine and satellite geophysical data sets reveal features of the remaining, submerged, 98% of the Scotia 124 Sea region between the outcrops. These data enable a more detailed and quantitative approach to the region’s plate kinematics. In contrast to long- used interpretations of the outcrop geology, these data do not prescribe the proximity of South Georgia to Tierra del Fuego in any past period. -

It may have contributed to the general ill-health of the members of Purdie Building, University of St Andrews, Scott’s polar party in 1912 but their deaths are more likely to have been caused by St Andrews KY16 9ST, a combination of frostbite, malnutrition and hypothermia. Some have argued that Scotland, UK Oates’s war wound in particular suffered dehiscence caused by a lack of vitamin C, but there is little evidence to support this. At the time, many doctors in Britain tel. +44 (0)1334 474720 overlooked the results of the experiments by Axel Holst and Theodor Frølich e-mail [email protected] which showed the effects of nutritional deficiencies and continued to accept the view, championed by Sir Almroth Wright, that polar scurvy was due to ptomaine poisoning from tainted pemmican.

Who Discovered the Northwest Passage? Janice Cavell1
ARCTIC VOL. 71, NO.3 (SEPTEMBER 2018) P.292 – 308 https://doi.org/10.14430/arctic4733 Who Discovered the Northwest Passage? Janice Cavell1 (Received 31 January 2018; accepted in revised form 1 May 2018) ABSTRACT. In 1855 a parliamentary committee concluded that Robert McClure deserved to be rewarded as the discoverer of a Northwest Passage. Since then, various writers have put forward rival claims on behalf of Sir John Franklin, John Rae, and Roald Amundsen. This article examines the process of 19th-century European exploration in the Arctic Archipelago, the definition of discovering a passage that prevailed at the time, and the arguments for and against the various contenders. It concludes that while no one explorer was “the” discoverer, McClure’s achievement deserves reconsideration. Key words: Northwest Passage; John Franklin; Robert McClure; John Rae; Roald Amundsen RÉSUMÉ. En 1855, un comité parlementaire a conclu que Robert McClure méritait de recevoir le titre de découvreur d’un passage du Nord-Ouest. Depuis lors, diverses personnes ont avancé des prétentions rivales à l’endroit de Sir John Franklin, de John Rae et de Roald Amundsen. Cet article se penche sur l’exploration européenne de l’archipel Arctique au XIXe siècle, sur la définition de la découverte d’un passage en vigueur à l’époque, de même que sur les arguments pour et contre les divers prétendants au titre. Nous concluons en affirmant que même si aucun des explorateurs n’a été « le » découvreur, les réalisations de Robert McClure méritent d’être considérées de nouveau. Mots clés : passage du Nord-Ouest; John Franklin; Robert McClure; John Rae; Roald Amundsen Traduit pour la revue Arctic par Nicole Giguère. -

The British Williams exploration party led by Captain William Smith discovered the northwest coast of the Antarctic Peninsula. The Russian Vostok and Mirnyy expedition led by Thaddeus Thadevich Bellingshausen sighted parts of the continental coast (Dronning Maud Land) without recognizing what they had seen. They discovered Peter I Island in January of 1821. • 1841 James Clark Ross sailed with the Erebus and the Terror through the ice in the Ross Sea, and mapped 900 kilometres of the coast. He discovered Ross Island and Mount Erebus. • 1892-93 Financed by Chr. Christensen from Sandefjord, C. A. Larsen sailed the Jason in search of new whaling grounds. The first fossils in Antarctica were discovered on Seymour Island, and the eastern part of the Antarctic Peninsula was explored to 68° 10’ S. Large stocks of whale were reported in the Antarctic and near South Georgia, and this discovery paved the way for the large-scale whaling industry and activity in the south.
