  • A Passagem De Robert Fitzroy E O HMS Beagle Pela Argentina Gabriel Passetti Doutorando/USP
    Anais Eletrônicos do VII Encontro Internacional da ANPHLAC Campinas – 2006 ISBN - 978-85-61621-00-1 Civilização britânica, barbáries americanas: a passagem de Robert FitzRoy e o HMS Beagle pela Argentina Gabriel Passetti Doutorando/USP Durante as décadas de 1820 e 1830, expedições britânicas percorreram as costas sul-americanas objetivando o mapeamento cartográfico das rotas do comércio imperial e a formalização de contatos comerciais e políticos com os Estados em formação após as independências ibéricas. Um dos locais mais visados foi a passagem do Oceano Atlântico para o Pacífico, rota obrigatória para o comercio imperial, o Estreito de Magalhães. Para ele, foram enviadas duas expedições que, juntas, permaneceram praticamente ininterruptamente entre 1827 e 1834, capitaneadas por Philip Parker King e Robert FitzRoy. Este artigo procura apresentar algumas observações iniciais desta documentação, procurando identificar os projetos para a América Latina e a visão construída da região e os povos que a habitavam. O final do século XVIII foi marcado pelo crescente interesse britânico e francês pelas rotas de circunavegação do globo e pelo mapeamento de regiões até então praticamente intocadas do interior das Américas, da África e da recém-descoberta Oceania. As expedições de James Cook (1768-1779) foram marcos importantes, pois estabeleceram as principais rotas, enquanto que as de Alexander von Humboldt (1799- 1804) construíram os modelos científicos a serem adotados pelos navegadores posteriores. O fim das guerras napoleônicas marcou a consolidação do poderio naval britânico e proporcionou um novo avanço, pois a Marinha Real, ampliada durante os combates, assumiu a posição de reguladora dos mares. Grandes veleiros foram enviados para verificar e detalhar as antigas cartas náuticas ibéricas das Américas, da África e da Ásia.

Those whom he had sent off on that fiasco seem to have been equally, and reasonably, terrified of catching Drake and of returning to report failure; and we can be sure that the always vehement Pedro Sarmiento de Gamboa let his views on their conduct be known.

  • Cloud Ridge Naturalists 2011 Field Notes
    Cloud Ridge Naturalists 2011 Field Notes by Sarah Drummond Winter’s greetings! As the days slowly start to lengthen here in the northern hemisphere, we reflect on some of our southern travels during the previous year. Our final trip of 2011, “In Darwin's Footsteps, Part II,” once again took up the trail of naturalist Charles Darwin and his famous voyage in the survey ship Beagle around South America between 1831 and 1834. In November 2010, Cloud Ridge visited several points on Darwin’s route in Argentine Patagonia, culminating with a cruise through Tierra del Fuego and ending in Punta Arenas, Chile. This year, we returned to Punta Arenas in early December, and from there we traveled north up Chile’s convoluted and mountainous coast. We went first to Puerto Hambre and the Cemetario Ingles, where Fitzroy’s predecessor as captain of the Beagle, Pringle Stokes, is buried. Next, we journeyed into Torres del Paine National Park to enjoy the spectacular alpine bloom and abundant wildlife as well as the park’s dramatic scenery. Further north in Chile’s lake district, we spent several days exploring the lush rainforest on Chiloe Island's west coast. Finally, we returned to Santiago and drove across the Andes via the Portillo Pass to end our journey in the wine country of Mendoza, Argentina. Like our previous sojourn “in Darwin’s footsteps,” this one took us through a wide range of landscapes and habitats, and illustrated both the incredible diversity and vulnerability of Patagonia. Abundant evidence of the geologic forces that amazed Darwin, however, served as a reminder that despite our power and numbers, humanity is never in control.
