Transits of the Northwest Passage to End of the 2019 Navigation Season Atlantic Ocean ↔ Arctic Ocean ↔ Pacific Ocean
TRANSITS OF THE NORTHWEST PASSAGE TO END OF THE 2019 NAVIGATION SEASON ATLANTIC OCEAN ↔ ARCTIC OCEAN ↔ PACIFIC OCEAN R. K. Headland and colleagues 12 December 2019 Scott Polar Research Institute, University of Cambridge, Lensfield Road, Cambridge, United Kingdom, CB2 1ER. <[email protected]> The earliest traverse of the Northwest Passage was completed in 1853 but used sledges over the sea ice of the central part of Parry Channel. Subsequently the following 314 complete maritime transits of the Northwest Passage have been made to the end of the 2019 navigation season, before winter began and the passage froze. These transits proceed to or from the Atlantic Ocean (Labrador Sea) in or out of the eastern approaches to the Canadian Arctic archipelago (Lancaster Sound or Foxe Basin) then the western approaches (McClure Strait or Amundsen Gulf), across the Beaufort Sea and Chukchi Sea of the Arctic Ocean, through the Bering Strait, from or to the Bering Sea of the Pacific Ocean. The Arctic Circle is crossed near the beginning and the end of all transits except those to or from the central or northern coast of west Greenland. The routes and directions are indicated. Details of submarine transits are not included because only two have been reported (1960 USS Sea Dragon, Capt. George Peabody Steele, westbound on route 1 and 1962 USS Skate, Capt. Joseph Lawrence Skoog, eastbound on route 1). Seven routes have been used for transits of the Northwest Passage with some minor variations (for example through Pond Inlet and Navy Board Inlet) and two composite courses in summers when ice was minimal (transits 149 and 167). -

The Viking Age
Laval University From the SelectedWorks of Fathi Habashi March, 2020 The iV king Age Fathi Habashi Available at: https://works.bepress.com/fathi_habashi/615/ The Viking Age INTRODUCTION The Viking Age (793-1066) is a period in history during which the Scandinavians expanded and built settlements throughout Europe. They are sometimes referred to as Norsemen and known to the Greek as Varangians. They took two routes: the East - - the present-day Ukraine and Russia, and the West mainly in the present-day Iceland, Greenland, Newfoundland, Normandy, Italy, and the British Isles. The Viking were competent sailors, adept in land warfare as well as at sea. Their ships were light enough to be carried over land from one river system to another. Viking ships The motivation of the Viking to invade East and West is a problem to historians. Many theories were given none was the answer. For example, retaliation against forced conversion to Christianity by Charlemagne by killing any who refused to become baptized, seeking centers of wealth, kidnapping slaves, and a decline in the profitability of old trade routes. Viking ship in Oslo Museum The Vikings raids in the East and the West of Europe VIKINGS IN THE EAST The Dnieber The Vikings of Scandinavia came by way of the Gulf of Finland and sailed up the Dvina River as far as they could go, and then carried their ships across land to the Dnieper River, which flows south to the Black Sea. They raided villages then they became interested in trading with the Slavs. Using the Dnieper, they carried shiploads of furs, honey, and wax south to markets on the Black Sea, or sailed across that sea trade in Constantinople. -
Glossary Glossary
Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts. -
Gerlache's Belgique in the Social Imaginary of Punta Arenas, 1897-1899

GERLACHE’S BELGIQUE IN THE SOCIAL IMAGINARY OF PUNTA ARENAS, 1897-1899 El BÉLGICA DE GERLACHE EN EL IMAGINARIO SOCIAL DE PUNTA ARENAS, 1897-1899 Mag. Mauricio Jara Fernández Universidad de Playa Ancha – Centre for Hemispheric and Polar Studies Valparaíso – Chile [email protected] FECHA DE RECEPCIÓN: 28 abril 2013 – FECHA DE ACEPTACIÓN: 2 junio 2013 ABSTRACT This article analyzes, based on the information in the newspaper El Magallanes of Punta Arenas and other publications, the perception that was created among the population of this southern Chilean city by the Antarctic expedition of between 1897 and 1899 and the activities carried out by the scientists and crew of the Belgique commanded by Lieutenant Adrien de Gerlache. Due to the fact that this expedition was made up of people from various nations and that it was aimed at reaching the South Pole provoked unusual interest and awoke an attractive interest for scientific topics and southern and antarctic policies. KEY WORDS Chile and Gerlache – Antarctica – Punta Arenas – Chilean Antarctic History RESUMEN El artículo analiza en base a informaciones del periódico El Magallanes de Punta Arenas y otras publicaciones, la percepción que se generó en la población de esta austral ciudad chilena por la expedición a la Antártica entre 1897 y 1899 y las actividades realizadas por los científicos y tripulantes del Bélgica comandado por el teniente Adrien de Gerlache. Por el hecho de ser una expedición integrada por personas de varias naciones y en busca del polo sur, su arribo y permanencia en la rada de Punta Arenas provocó un inusitado interés y despertó una atractiva afición por los temas científicos y políticos australes y antárticos. -
Climbing on Kangchenjunga Since 1955
JOSE LUIS BERMUDEZ Climbing on Kangchenjunga since 1955 he history of climbing on Kangchenjunga in the years immediately T after the first ascent is easily told. Nothing happened for almost twenty years. There were many reasons for this. The sheer remoteness of the mountain must surely be one, as must the political difficulties in getting permission to climb the mountain either from Sikkim or from Nepal. And it is understandable that in the late 1950s the attention of mountaineers should have been focused on the 8000-metre peaks that were still unclimbed. Kangchenjunga's status as a holy mountain was a further obstacle. So it is not entirely surprising that there were no expeditions to the Kangchenjunga massif between 1955 and 1973. When climbers did eventually return to Kangchenjunga they found obvious and formidable challenges. Kangchenjunga has four distinct sum mits over 8000m. 1 The 1955 expedition climbed the Main Peak, which is the highest at 8586m. But that still left three virgin summits which were not much shorter: the South Summit at 8476m, the Central Summit at 8482m and the West Summit (better known as Yalung Kang) at 8505m. Equally significant were the two routes that had been attempted on the Main Peak before the successful expedition. The route taken by the first ascensionists was the Yalung (SW) Face, approached from the Yalung gla cier on the Nepalese side of the frontier ridge. As emerged very clearly in the Seminar, the Yalung Face was not the route favoured by most previous attempts on the mountain. The three expeditions in the late 1920s and early 1930s had thought that the North Ridge was the key to the mountain. -

SEADEVCON Maritime Award 2020 Goes to Professor Dr. Markus Rex
SEADEVCON Maritime Award 2020 Goes to Professor Dr. Markus Rex Leader of largest polar expedition in history - MOSAiC project investigating Arctic as epicenter of global warming - Award presented by Arved Fuchs - “A game changer in climate research” - Prize winner to participate virtually from North Pole Hamburg, 25 August 2020. The SEADEVCON Maritime Award 2020 (www.seadevcon.com) goes to Professor Dr. Markus Rex, Head of Atmospheric Physics in the Climate Sciences Division at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, in Potsdam. Rex leads the on-going historic project named MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) involving hundreds of researchers from 20 countries (www.mosaic-expedition.org). Following in the footsteps of Fridtjof Nansen’s ground-breaking expedition with his wooden sailing ship Fram in 1893-1896, the MOSAiC expedition brings a modern research icebreaker, the German ship Polarstern, close to the north pole for a full year including for the first time in polar winter. The data gathered will be used by scientists around the globe to take climate research to a completely new level. The SEADEVCON Maritime Award is to recognize annually a personality whose “lifetime achievement is exemplary for the fight of a sustainable and respectful use of the world’s seas”. Highlighting the principle of continuity, the author and expedition leader Arved Fuchs, winner of the prize in 2019, will present this year’s honoree. Fuchs wholeheartedly endorses this selection: “The work of Markus Rex and his colleagues is simply no less than a game changer. I couldn’t be more supportive of what they are doing.” Carsten Bullemer, SEADEVCON founder and organiser, explains the choice: “Arved Fuchs is a hard act to follow, but in Markus Rex we have found a worthy successor. -
CAMBRIDGE LIBRARY COLLECTION Books of Enduring Scholarly Value
Cambridge University Press 978-1-108-07100-0 - A Brief Narrative of an Unsuccessful Attempt to Reach Repulse Bay: ...In his Majesty’s Ship Griper, in the Year MDCCCXXIV George Francis Lyon Frontmatter More information CAMBRIDGE LIBRARY COLLECTION Books of enduring scholarly value Polar Exploration This series includes accounts, by eye-witnesses and contemporaries, of early expeditions to the Arctic and the Antarctic. Huge resources were invested in such endeavours, particularly the search for the North-West Passage, which, if successful, promised enormous strategic and commercial rewards. Carto- graphers and scientists travelled with many of the expeditions, and their work made important contributions to earth sciences, climatology, botany and zoology. They also brought back anthropological information about the indigenous peoples of the Arctic region and the southern fringes of the American continent The series further includes dramatic and poignant accounts of the harsh realities of working in extreme conditions and utter isolation in bygone centuries. A Brief Narrative of an Unsuccessful Attempt to Reach Repulse Bay This short work, featuring a number of attractive engravings, traces an abortive expedition to the Canadian Arctic. George Francis Lyon (1795–1832), naval officer and explorer, had accompanied William Parry on a previous expedition in search of the North-West Passage. In 1824 Lyon was instructed to return to Repulse Bay and to explore the mainland. Unfavourable weather conditions forced Lyon to turn back after a few months, and he published this account of the experience the following year. Lyon’s text is notable for his descriptions of encounters with Inuit, with whom he spent a great deal of time. -

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.
