Voyages as exercises of the gaze

This article focuses the relationship between journeys and photographs especially among anthropologists who travel. Having travelled to the Upper Negro River as an advisor of a PhD student, I discuss what digital photographs may mean in a context where verbal communication is impossible. Real or imaginary journeys are a source of images, reports, or travel logs in which it is difficult to discern what is real and what is fiction. After discussing a few famous scientific and literary journeys, the article focuses on some anthropological journeys and concludes that images produced by anthropologists are a result of trained intuition, a sensitive gaze, and memories of former travels. The article includes photographic essays that incorporate pictures I took in February 2012 among the Hupd'äh, in the Upper Negro River region.

The objectives of the US Exploring Expedition's circumnavigation (1838-1842): longitude, nautical charting and the establishment of modern geographic coordinates

This article analyzes the main objectives of the scientific voyage to circumnavigate the earth, undertaken by the United States from 1838 to 1842. Charting was one of the most important of the scientific and strategic goals of the exploratory voyage. The initiative for the undertaking was the search for exact positioning on the high seas after the establishment of the longitude system, when nautical charts and maps from various countries were compared, and other, new ones were drawn. The United States participated in this international effort, leading to the creation of its own cartographic system.

Os objetivos da circunavegação da U.S. Exploring Expedition (1838-1842): longitude, mapeamento náutico e instituição das coordenadas geográficas modernas

Analisa o principal objetivo da viagem científica de circunavegação realizada pelos EUA entre 1838 e 1842. A tarefa de mapeamento destaca-se entre outras metas científico-estratégicas da viagem exploratória. A iniciativa da empreitada foi movida pela busca da exata localização em alto-mar após a instituição do sistema de longitudes, quando cartas náuticas e mapas de vários países foram conferidos, e outros, novos, desenhados. Os EUA participaram desse esforço internacional, dando início à constituição de um sistema cartográfico próprio.
