Cânions da América do Sul e a Década dos Oceanos

Cânions Submarinos desempenham um importante papel nos ecossistemas marinhos ao provocar alterações locais na temperatura, salinidade, nutrientes, transporte de sedimentos e até mesmo poluentes no ambiente marinho. Marcos V. B. Silva e Tereza C. M. Araújo integrantes do inct AmbTropic II (GT2.1 - (Geodiversidade, Biodiversidade e Recursos Vivos da Plataforma Continental) publicaram nesta semana no periódico Frontiers in Marine Sciences (IF: 4.912) uma revisão sistemática sobre os cânions da América do Sul intitulado "The South American Advances in Submarine Canyons Studies and Their Link to the Ocean Decade"

ABSTRACT

Submarine canyons have a relevant role in marine ecosystems. They are responsible for oceanographic conditions such as variability of temperature and salinity, sediment transport, nutrients, and even pollutants amongst marine areas. Submarine canyon studies have been growing and reaching prominence due to their importance in the Blue Economy. Initiatives to promote sustainable development for the ocean have been discussed in the Ocean Decade. Although canyons studies are increasing, how can we integrate these with the Ocean Decade outcomes? Thus, we aim to demonstrate an overview of the advances of submarine canyons studies and their link to the Ocean Decade for South America. We analyzed 160 studies divided into spatiotemporal analysis and study approaches according to the Ocean Decade outcomes. We discuss these articles, building a timeline and argumentative topics considering the advances, and discuss gaps to predict the future of submarine canyons studies in the Ocean Decade and Blue Economy context.
