Navegação nas regiões polares

Abstract

This project aims to not only draw attention to polar navigation peculiarities and number and analyze the various complicating factors and drawbacks. Besides that, it is also about the socioeconomic aspects involved in the passages and it still undertakes to make a prospect, studying the diverse consequences that this activity may bring about. This project commences with the definition the limitation of the polarregions extension. Then, both Arctic and Antarctic physical features interesting for seafarers are explored. And highlighting the navigation scope, one explains what makes these regions so special, accentuating the main navigation-affecting factors, both meteorological and geographic. Finally, three pieces of navigation aids equipment (magnetic compass, gyroscopic compass and radar) have been chosen to illustrate the influence these equipment they are under on these polar regions and how their performance can become limited and doubtful. When it comes to radar, among the many complications, four were picked due to their importance: snow, fog, ice and icebergs.
