Neste trabalho foram analisadas as taxas de mudança da frente da geleira Polar Club e comparadas com a variabilidade interanual da temperatura do ar, na Península Potter, ilha Rei George, a fim de compreender o impacto direto das alterações do clima local na dinâmica das áreas livres de gelo. Foi utilizada uma série de dez cenas de imagens do satélite Landsat e dados de temperatura do ar superficial entre 1986 e 2011. Os resultados evidenciam uma tendência no aumento na temperatura do ar de 0,04 ºC por ano, o que resultou no incremento de 1,03 ºC nas temperaturas médias do ar para o período de 26 anos analisados. -
Plan Anual Antártico Del Programa Antártico Argentino 2018-2019
Programa Antártico Argentino Plan Anual Antártico 2018-2019 INTRODUCCIÓN La Argentina reivindica soberanía sobre el Sector Antártico Argentino, comprendido entre los meridianos 25° y 74° de longitud Oeste al sur del paralelo de 60° de latitud Sur, con fundamento en títulos históricos, geográficos, geológicos y jurídicos. La Argentina tiene presencia permanente e ininterrumpida en la Antártida desde el 22 de febrero de 1904, en que se estableciera la primera estación científica (Base Orcadas) en la Isla Laurie, Archipiélago de las Islas Orcadas del Sur. La Argentina, por tanto, tiene la presencia continua más antigua en la Antártida. La Argentina tiene seis bases permanentes (Carlini, Orcadas, Esperanza, Marambio, San Martín y Belgrano II) y siete bases temporarias (Brown, Primavera, Decepción, Melchior, Matienzo, Cámara y Petrel). Todas están situadas en el Sector Antártico Argentino. La Dirección Nacional del Antártico administra dos de ellas (las Bases Carlini y Brown) y el Ministerio de Defensa, a través del Comando Conjunto Antártico, administra las otras once. La Argentina es uno de los doce países que participaron en la Conferencia de Washington sobre la Antártida de 1959, y eso la llevó a ser uno de los doce signatarios originarios del Tratado Antártico. El Tratado establece que la Antártida se utilizará exclusivamente para fines pacíficos y erige a la ciencia en el centro de la actividad antártica. El artículo IV del Tratado resguarda adecuadamente las reivindicaciones de soberanía en la Antártida. Por tanto, uno de los ejes de la política exterior argentina es continuo fortalecimiento del conjunto de normas surgidas a partir del Tratado Antártico. Los lineamientos de la Política Antártica Nacional (PAN) están definidos por el Decreto 2316/90, cuyo objetivo principal es el P á g i n a 2 | 265 Programa Antártico Argentino Plan Anual Antártico 2018-2019 afianzamiento de los derechos argentinos de soberanía en la Antártida. -

1 Inhabiting the Antarctic Jessica O'reilly & Juan Francisco Salazar
Inhabiting the Antarctic Jessica O’Reilly & Juan Francisco Salazar Introduction The Polar Regions are places that are part fantasy and part reality.1 Antarctica was the last continent to be discovered (1819–1820) and the only landmass never inhabited by indigenous people.2 While today thousands of people live and work there at dozens of national bases, Antarctica has eluded the anthropological imagination. In recent years, however, as anthropology has turned its attention to extreme environments, scientific field practices, and ethnographies of global connection and situated globalities, Antarctica has become a fitting space for anthropological analysis and ethnographic research.3 The idea propounded in the Antarctic Treaty System—that Antarctica is a place of science, peace, environmental protection, and international cooperation—is prevalent in contemporary representations of the continent. Today Antarctic images are negotiated within a culture of global environmentalism and international science. Historians, visual artists, and journalists who have spent time in the Antarctic have provided rich accounts of how these principles of global environmentalism and 1 See for instance Adrian Howkins, The Polar Regions: An Environmental History (Cambridge, UK: Polity, 2016). 2 Archaeological records have shown evidence of human occupation of Patagonia and the South American sub-Antarctic region (42˚S to Cape Horn 56˚S) dating back to the Pleistocene–Holocene transition (13,000–8,000 years before present). The first human inhabitants south of 60˚S were British, United States, and Norwegian whalers and sealers who originally settled in Antarctic and sub-Antarctic islands during the early 1800s, often for relatively extended periods of time, though never permanently 3 See for instance Jessica O’Reilly, The Technocratic Antarctic: An Ethnography of Scientific Expertise and Environmental Governance (Ithaca, NY: Cornell University Press, 2017); Juan Francisco Salazar, “Geographies of Place-making in Antarctica: An Ethnographic Approach,” The Polar Journal 3, no. -
Analysis and Prediction of Changes in the Temperature of the Pure Freshwater Ice Column in the Antarctic and the Arctic
Analysis and prediction of changes in the temperature of the pure freshwater ice column in the Antarctic and the Arctic A.A. Fedotov, V.V. Kaniber, P.V. Khrapov Abstract – This paper investigates the initial boundary value problem for a non-stationary one-dimensional heat equation that simulates the temperature distribution in freshwater ice near the Earth's poles. The mathematical model has been constructed taking into account solid-liquid phase transitions. Data from meteorological stations were used to determine the model parameters, with the help of which the necessary physical and thermophysical characteristics of the computational domain were obtained. For the numerical solution of the problem, the finite volume method (FVM) was used. In order to analyze changes in the temperature field of ice and determine the time required to reach a non-stationary periodic regime, graphs of temperature versus depth were plotted for January at two stations. The study of the results showed that it takes about 50 years of modeling with constant initial data for the temperature of an ice layer up to 20 m deep to reach the periodic regime. For the obtained periodic regime, the temperature versus depth dependences for each month were plotted, and the depth of the active layer, as well as the depth of zero annual amplitudes were found for each meteorological station. A forecast of the ice temperature regime for 2100 was modeled for three Representative Concentration Pathway (RCP) scenarios of global warming: moderate RCP2.6, corresponding to the current emissions of RCP7 and adopted at the Paris Agreement in 2015 RCP1.9. -

On both occasions a pair of specimens with winter plumage was observed. The Hudsonian Godwit Limosa haemastica (Linnaeus tide and each time birds were feeding in the intertidal 1758) is a neartic migratory species that breeds in Alaska zone. These individuals showed the winter plumage and Canada during summer and spends its non-breeding pattern: dark reddish chest and white ventral region, black period in the southernmost regions of South America primaries and tail feathers, a long upturned bill pink at during the boreal winter. -

History of Antarctica - Wikipedia, the free encyclopedia Page 1 of 13 Coordinates: 67°15′S 39°35′E History of Antarctica From Wikipedia, the free encyclopedia For the natural history of the Antarctic continent, see Antarctica. The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term Antarctic, referring to the opposite of the Arctic Circle, was coined by Marinus of Tyre in the 2nd century AD. The rounding of the Cape of Good Hope and Cape Horn in the 15th and 16th centuries proved that Terra Australis Incognita ("Unknown Southern Land"), if it existed, was a continent in its own right. In 1773 James Cook and his crew crossed the Antarctic Circle for the first time but although they discovered nearby islands, they did not catch sight of Antarctica itself. It is believed he was as close as 150 miles from the mainland. In 1820, several expeditions claimed to have been the first to have sighted the ice shelf or the continent. A Russian expedition was led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev, a British expedition was captained by Edward Bransfield and an American sealer Nathaniel Palmer participated. The first landing was probably just over a year later when American Captain John Davis, a sealer, set foot on the ice. Several expeditions attempted to reach the South Pole in the early 20th century, during the 'Heroic Age of Antarctic Exploration'. Many resulted in injury and death. Norwegian Roald Amundsen finally reached the Pole on December 14, 1911, following a dramatic race with the Englishman Robert Falcon Scott.
