Propiedades físicas químicas em dois pontos fixos na Enseada do Flamengo, Ubatuba (SP), no período de 03 a 07/04/77

Abstract

Temporal variation of some physical and chemical observations was performed during four days with S1:X hour of intervals at Th'O fixed stations at the Enseada do Fla-mengo ~ Ubatuba~ são Paulo. The salinity (34.3 % 0 -35.1% 0) and temperature vaZues (about 26°C) are typical of local coastal waters. The dissolved oxygen shows supersaturation content with some exceptions. The nitrogen (nitrite and nitrate) forms have very lO1.J values~ with a maximum of 1.0 ~g-at/l (nitrate). Other nutrients~ like phosphates (0.15 -0.80 ~g-at/l) and silicates (5.0-21.5 ~g-at/l) and the relationship N:P (1:3)~ sh01.J the poor terrigenous contribution and small bioproductivity. The pH and alcalinity was normal for sea water.
