Is copper an inhibiting factor for primary production in the upwelling waters of Cabo Frio?

Abstract: O objetivo deste trabalho foi testar a hipótese de que espécies inorgânicas de cobre poderiam atuar como um fator inibidor da produção primária nas águas de ressurgência de Cabo Frio. Para tal, amostras de água foram coletadas de quatro profundidades diferentes em três estações costeiras ao largo de Cabo Frio, nas quais determinou-se a concentração de espécies macronutrientes, pH, oxigênio dissolvido, alcalinidade, concentração de material particulado, clorofila a, produção primária, especiação de cobre (Cu(II… Show more

“…21,22 Sepetiba Bay (stations 15 and 16) is contaminated by releases of cadmium and zinc from a metallurgic industries and in lesser degree by sewage and oil, while Guanabara Bay (stations 06 to 10) receives heavy loads of a diversity of organic and inorganic contaminants. According to Rebello et al chromium, zinc and copper are the most relevant amongst trace metal contaminants in Guanabara Bay.…”

“…Coastal upwelling is a very important phenomenon because it brings nutrient-rich water to the coast [3,4] improving fishery activities [5]. Alkenone-based temperature analysis indicated that upwelling cooling patterns in the Cabo Frio area have intensified over the last 700 years [6].…”

“…A ressurgência costeira é um fenômeno importante porque traz águas ricas em nutrientes para a costa (Guimarães et al, 2005;Carbonel e Valentin, 1999) e favorece as atividades pesqueiras (Diniz et al, 2003). Análises de temperatura através de alquenonas indicaram que os padrões de resfriamento da ressurgência na área de Cabo Frio se intensificaram nos últimos 700 anos (Mahiques et al, 2005).…”
