Antártida, Antártida, altar de hielo y luz, reserva de agua y paz. Manuscrito en una servilleta Hotel Savoy, Rosario 1992 Antarctica, the end of the world: boasting the most hostile climatic conditions, the coldest place on earth with temperatures reaching -80 °C in winter, the largest frozen desert in the world, continaing 90% of the world's ice (approximately 70% of the world's fresh water), no permanent human residents, and no indigenous population. Yet over 4,000 research scientists from 27 different nations are constantly monintering the ecoszone of this southernmost continent, not to mention the hundreds and thousands of new eco-tourists aboard the cruise ships navigating the Half Moon Island, Whalers Bay, Deception Island, Paradise Harbor, Port Lockroy, Petermann Island. “[…] Vowing one day to venture to these invariably far-flung and often wholly inhospitable lands. Antarctica's treacherous, spiny tendril was one such irresistible location […] Like the bristly tail of some giant, prehistoric sea creature, the Antarctic Peninsula thrusts out past the Antarctic Circle, lunging vainly toward its sibling, the Andes, across the infamous Drake Passage. I'm standing on the bow of a modern ice vessel watching hefty chunks of disintegrating pack ice thud against the hull as we pick our way gingerly through a narrow channel.

  • An Arctic Expedition To
    The Association of Former Students of Texas A&M EXPEDITION TO AN ARCTIC Aboard the Exclusively Chartered, Five-Star L’Austral Jan. 28 - Feb. 10, 2020 Howdy, Ags! “Everything wears an aspect of unreality,” Ernest Shackleton wrote. “Icebergs hang upside down in the sky; the land appears as layers of silvery or golden cloud. Cloud‑banks look like land, icebergs masquerade as islands...” Watch as normal human scales and reference points disappear amidst the grandeur of nature in its most pristine form, from extended sunrises that paint the icescape in soft shades of pink to the lingering golden light of the austral summer, where humpback whales, leopard seals and Adélie penguins swim among sparkling turquoise glaciers and glimmering icebergs. Be among the fortunate few to set foot on the continent of Antarctica, and see how its spectacular illuminations reveal the majesty and contrasts of this unique wilderness during your extraordinary 14‑day journey to the bottom of the world. Retrace the sea lanes navigated by storied explorers Shackleton, Amundsen and Scott, inspired to seek out the final frontier of “The White Continent.” Cruise for nine nights aboard the exclusively chartered, Five‑Star, ice‑class L’Austral, one of the finest vessels in Antarctic waters. With private balconies in 95 percent of its ocean‑view accommodations and encompassing state‑of‑the‑art ship design and technology, L’Austral sets the very highest standards in elegance and comfort. The onboard expedition team of naturalists will guide you on excursions aboard sturdy Zodiac craft to satisfy your appetite for exploration amid floating ice sculptures, intricate ecosystems and abundant wildlife, especially penguins and seals that exhibit little or no fear of humans.

  • Public Information Leaflet HISTORY.Indd
    British Antarctic Survey History The United Kingdom has a long and distinguished record of scientific exploration in Antarctica. Before the creation of the British Antarctic Survey (BAS), there were many surveying and scientific expeditions that laid the foundations for modern polar science. These ranged from Captain Cook’s naval voyages of the 18th century, to the famous expeditions led by Scott and Shackleton, to a secret wartime operation to secure British interests in Antarctica. Today, BAS is a world leader in polar science, maintaining the UK’s long history of Antarctic discovery and scientific endeavour. The early years Britain’s interests in Antarctica started with the first circumnavigation of the Antarctic continent by Captain James Cook during his voyage of 1772-75. Cook sailed his two ships, HMS Resolution and HMS Adventure, into the pack ice reaching as far as 71°10' south and crossing the Antarctic Circle for the first time. He discovered South Georgia and the South Sandwich Islands although he did not set eyes on the Antarctic continent itself. His reports of fur seals led many sealers from Britain and the United States to head to the Antarctic to begin a long and unsustainable exploitation of the Southern Ocean. Image: Unloading cargo for the construction of ‘Base A’ on Goudier Island, Antarctic Peninsula (1944). During the late 18th and early 19th centuries, interest in Antarctica was largely focused on the exploitation of its surrounding waters by sealers and whalers. The discovery of the South Shetland Islands is attributed to Captain William Smith who was blown off course when sailing around Cape Horn in 1819.

INTRODUCTION Article VII of the Antarctic Treaty and Article 14 of the Protocol on Environmental Protection to the Antarctic Treaty enable Antarctic Treaty Consultative Parties to conduct inspections in order to promote the objectives and ensure compliance with the provisions of the Antarctic Treaty and its Protocol. Article VII of the Antarctic Treaty establishes the right of free access for observation and inspection by the Contracting Parties. Observers designed under Article VII (1) “shall have complete freedom of access”, including the conducting of aerial observations, “at any time to any or all areas of Antarctica.” The facilities that may be inspected include “all stations, installations and equipment within those areas, and all ships and aircraft at points of discharging or embarking cargoes or personnel in Antarctica.” Article 14 of the Protocol establishes that Antarctic Treaty Consultative Parties “shall arrange, individually or collectively, for inspections by observers to be made in accordance with Article VII of the Antarctic Treaty.” During inspections, observers should be given access to “all parts of stations, installations, equipment, ships and aircraft open to inspection under Article VII of the Antarctic Treaty, and to all records” that are maintained at those facilities in accordance to Protocol requirements.

Corrections have been entered in footnotes, along with appropriate comments. A monologue by Alan Carroll, Base Leader at Port Lockroy, between 28 November 1954 and 2 March 1957, who subsequently worked at the same location in November- December 2006 on behalf of the United Kingdom Antarctic Heritage Trust. This recording was made at The Language Centre of the University of Oxford. --------------------------------- (00:18) Hello - my name's Alan Carroll and I'm recording this tape at the University of Oxford (from where I officially retired in the autumn of 1998.) I was stationed at Port Lockroy from the end of November 1954 until early March 1957.1 I was a bit of a restless individual in my younger days – I attended Wallingford Grammar School during the latter part of the Second World War, having been evacuated from Ealing in west London before serious bombing started. While I was at Wallingford, I played a lot of rugby and was selected to play for Oxfordshire; I spent holidays messing about with boats on the river and also joined the local Air Training Corps. Towards the end of the war I returned to Ealing, and continued at the Drayton Manor Grammar School where I matriculated, but I didn't want to go to College straight away and so I went to work at the Middlesex Oil & Chemical Laboratory in West Drayton. When I was called up for National Service, I was one of the lucky few who asked for and was selected for aircrew duty.
