  • 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.

  • Antarctica, the Falklands & South Georgia
    Snow Petrel (János Oláh). ANTARCTICA, THE FALKLANDS & SOUTH GEORGIA 29 NOVEMBER – 17 DECEMBER 2016 LEADER: JÁNOS OLÁH All reports describe the amazing experience to be had on this tour! However, even with expectations so high it never dissapoints. It is an outstanding and uplifting feeling to witness the wildlife spectacle of this largely unspoilt part of the World. It is easy to fall in love with the area and by the end of the tour most people just do not want to leave the boat and there is an unspoken sadness on the final day! Seeing the magical Falklands with its special birds, tens of thousands of King Penguins on South Georgia or setting foot on the ’white continent’ are things never to be forgotten! This year we had no offical pre-tour extension but most participants did arrive to Ushuaia earlier and got to see some great birds around town like Ashy-headed Goose, Magellanic Woodpecker, Magellanic Tapaculo and White-throated Treerunner just to name but a few. The cruise itself visited the Falklands, South Georgia, the South Orkneys, the Antarctic Peninsula, a little bit of the Weddell Sea and the South Shetlands before setting sail across the Drake Passage back to Ushuaia. Our ship was the cosy and well equipped Plancius and we soon got accustomed with this fine boat. This year there were very few birders on board and only a two more in addition to the Birdquest group! However there were no lack of enthusiasm and our little team maintained an almost constant watch during our days at sea, enabling us to achieve some impressive sightings of seabirds and marine mammals.

    Exploration, Exploitation and Explanation: Some Historical Relations in Antarctica. by James Gardner Outline Proposition: Antarctica has become known to us through interactions within and among Exploration (mapping), Explanation (science) and Exploitation (use and consumption of extant resources). Evidence: Revealed through the historical record of travel to and within the region over the past 250 years, a process that continues today and points to a future. Focus: Primarily the Antarctic Peninsula and adjacent Southern Ocean and Sub-Antarctic Islands and with some reference to continental Antarctica. Some Background How did Antarctica come to be as it is? What is it like today? How is it governed? What is its future?

  • United States Antarctic Activities 2003-2004
    United States Antarctic Activities 2003-2004 This site fulfills the annual obligation of the United States of America as an Antarctic Treaty signatory to report its activities taking place in Antarctica. This portion details planned activities for July 2003 through June 2004. Modifications to these plans will be published elsewhere on this site upon conclusion of the 2003-2004 season. National Science Foundation Arlington, Virginia 22230 November 30, 2003 Information Exchange Under United States Antarctic Activities Articles III and VII(5) of the ANTARCTIC TREATY Introduction Organization and content of this site respond to articles III(1) and VII(5) of the Antarctic Treaty. Format is as prescribed in the Annex to Antarctic Treaty Recommendation VIII-6, as amended by Recommendation XIII-3. The National Science Foundation, an agency of the U.S. Government, manages and funds the United States Antarctic Program. This program comprises almost the totality of publicly supported U.S. antarctic activities—performed mainly by scientists (often in collaboration with scientists from other Antarctic Treaty nations) based at U.S. universities and other Federal agencies; operations performed by firms under contract to the Foundation; and military logistics by units of the Department of Defense. Activities such as tourism sponsored by private U.S. groups or individuals are included. In the past, some private U.S. groups have arranged their activities with groups in another Treaty nation; to the extent that these activities are known to NSF, they are included. Visits to U.S. Antarctic stations by non-governmental groups are described in Section XVI. This document is intended primarily for use as a Web-based file, but can be printed using the PDF option.

  • Recent Environmental Changes on the Antarctic Peninsula As Recorded in an Ice Core from the Bruce Plateau
    Recent Environmental Changes on the Antarctic Peninsula as Recorded in an Ice Core from the Bruce Plateau DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Bradley Patrick Goodwin Graduate Program in Atmospheric Science The Ohio State University 2013 Dissertation Committee: Professor Ellen Mosley-Thompson, Advisor Professor David Bromwich Professor Jay Hobgood Professor Lonnie Thompson Copyrighted by Bradley Patrick Goodwin 2013 Abstract Dramatic changes in net accumulation and temperature on the Antarctic Peninsula have been observed over the last century. Ice core-derived proxies provide histories of these variables extending beyond the relatively short instrumental records available for this region. Histories of net annual accumulation and 18O from an ice core drilled to bedrock on the Bruce Plateau in the Antarctic Peninsula provide an additional multi-century record of climate variability in this region. Time series for the period 1750-2009 CE are generated, evaluated for changes over time and compared to other relevant environmental data. Comparisons to satellite and station data are conducted over the relatively short duration of these records. Large scale atmospheric oscillations, such as the Southern Annular Mode and El Niño-Southern Oscillation, are investigated as potential drivers of the observed changes from 1900-2009 CE. Ice core records from other locations are analyzed to provide a larger spatial context for the changes observed on the Antarctic Peninsula from 1750 to 2009 CE. Sulfate in ice cores can originate from sea salt, oceanic biological productivity, volcanic activity, and anthropogenic influences. Different methods are used to distinguish the sulfate contributed by each of these sources and thereby to generate source specific sulfate histories.

Geopolitical concerns center on the rising presence of China and Russia in the Antarctic and the integrity of the Bruce Vaughn Antarctic Treaty System (ATS), which provides a framework for governing the region. Specialist in Asian Affairs Environmental issues, particularly those related to climate change, also are prominent in Antarctica, due to current and projected future rates of melting ice in the region, which cause some scientists to assert that Antarctica represents a significant source for global sea-level rise Kezee Procita under future warming conditions. Much of the research on understanding and projecting rates of Senior Research Librarian melting ice and its potential contribution to global sea-level rise relies on satellite data, as well as scientific work conducted in Antarctica. Most of the research done by U.S. scientists is overseen and funded by the National Science Foundation.

  • The Antarctic Seismographic Argentinean Italian
    The Antarctic Seismographic Argentinean Italian Network - ASAIN Improving the instrumental coverage in Antarctica Marino Russi, Claudio Cravos, Damiano Pesaresi & Milton P. Plasencia L. Istituto Nazionale di Oceanografia e di Geofisica Sperimentale - OGS Abstract: Scientific investigations of the Scotia Sea region are crucial to understand the history of the Antarctic continent tectonic evolution and the influence of the aperture of the Drake passage in establishing the Circumpolar Antarctic Seismographic Argentinean Italian Network Location Map Antarctic Current, as stressed by many authors (e.g. Lodolo, 2008). The Scotia Sea occupies a roughly rectangular area of about 900.000 km2 . This area is limited on three sides by the Scotia Arc, formed by islands and oceanic ridges, which is a remnant of the mountain chain that joined the South American Andes Antarctic Branch to the Antarctic Peninsula. The western border is represented by the about 1000 km wide Drake passage, that separates today the Tierra del Fuego in South Tierra del Fuego Branch America from the Antarctic continent. A review of the tectonics and evolution EFI of the Scotia Sea can be found in Barker, 2001. The start of the geophysical studies in this area dates back to several decades ago, but only after 1990 IRIS consortium stations instrumental passive seismology started to be widely applied to investigate the DSPA HOPE crustal properties and the properties of the seismic sources responsible for the strong Centenary Earthquake epicentre seismicity level observed along the Scotia plate boundaries. ASAIN started TRVA operation in 1992 when a temporary seismograph was installed at the Argentinean Base Esperanza. It grew quickly during the nineties and today five stations are operated in Antarctica and two in Tierra del Fuego.
