Navegação nas regiões polares

Abstract

The Arctic thaw has encouraged shipping companies and countries of north region to invest in polar navigation in general, as a less costly alternative to traditional maritime trade routes. The base station “Comandante Ferraz” in Antarctic put Brazil among the countries that have the need to develop techniques and knowledge about the ice navigation. This topic is still little known in the Brazilian maritime community and should increasingly be discussed and demystified. This monograph discusses the peculiarities and challenges of navigation in the Polar Regions, starting from the general and geographic definition about the south polar region and the north polar region of the Earth. It’s presented also the specifications of polar ships, the adequate preparation for the defeats (which greatly differs from the preparation of ships sailing in regions without the presence of ice), and information about the equipment and navigation systems, which performance is changed due to the continued presence of ice. Then it’s exposed the visual observations of the sailor and its traps caused by frozen sea and frozen land. "Navigation in Polar Regions - Challenges of a Peculiar Navigation" brings knowledge of extreme importance to the navigators who want to familiarize themselves with the polar navigation.
