Abstract

O objetivo deste é compreender a variabilidade da produtividade marinha, na plataforma continental sudeste do Brasil, ao longo do Holoceno. Neste sentido, este projeto deverá obter um registro sedimentar de alta resolução em uma área da plataforma continental que apresenta altos índices de produção primária atual (zona de ressurgência), e analisar, sob um enfoque de indicadores múltiplos (multi-proxies) orgânicos e inorgânicos, a variabilidade decadal e/ou secular da produtividade biológica.
