Resumo

A costa atlântica ibérica é tipicamente caracterizada por incisões que afectam profundamente a plataforma continental, vulgarmente conhecidas por canhões submarinos. Entre os canhões submarinos localizados ao largo da costa atlântica portuguesa encontram-se os canhões do Porto, Aveiro, Nazaré e Lisboa-Setúbal, destacando-se os canhões da Nazaré e Lisboa-Setúbal pelas suas dimensões, características e dinâmica. A Nazaré é uma pequena cidade localizada a cerca de 100 km a norte de Lisboa, conhecida mundialmente pela ocorrência de ondas gigantes recentemente surfadas. O Canhão da Nazaré é um dos maiores canhões submarinos da Europa. Tem cerca de 225 km de comprimento e 5000 m de profundidade máxima, com vários declives acentuados. O presente trabalho visa contribuir para a compreensão geral da dinâmica dos sistemas de canhões ao longo da costa atlântica portuguesa. É discutido o Canhão da Nazaré e o seu swell gigante. Por fim, é feita uma breve descrição das ondas gigantes mais recentemente surfadas e listadas no livro do Guinness.
