摘要

2010年冬季,在里约热内卢和圣保罗北部,包括弗里奥角、瓜纳巴拉湾、塞佩蒂巴湾和乌巴图巴,建立了39个海洋观测站。利用溶解的无机营养物(铵、亚硝酸盐、硝酸盐、磷酸盐和硅酸盐)和叶绿素-a数据研究了发生在大陆架上的生物地球化学和物理过程。确定了四种主要的营养来源:当地的河口羽流;起源遥远的沿海水域;南大西洋中部水侵入大陆架;以及底部沉积物的悬浮和再矿化过程。

Nutrients and chlorophyll-a distribution over the continental margin between Cabo Frio (RJ) and Ubatuba (SP): winter of 2010
Thirty nine oceanographic stations were conducted off Rio de Janeiro and northern Sao Paulo, encompassing Cabo Frio, Guanabara Bay, Sepetiba Bay and Ubatuba in the winter of 2010. Dissolved inorganic nutrients (ammonium, nitrite, nitrate, phosphate and silicate) and chlorophyll-a data were used to investigate biogeochemical and physical processes occurring on the continental shelf. Four major sources of nutrients were identified: local estuarine plumes; remote origins coastal waters; intrusion of South Atlantic Central Water over the continental shelf; and bottom sediments ressuspension and remineralization processes.
