Abstract

Vertical profiles of physical (temperature and salinity) and chemical (ammonium, phosphate and silicate) properties were monthly obtained in seven oceanographic stations located in Santos Bay and in Santos channel, as part of a project which aims to determine the influence of the Santos estuarine system on the adjacent continental shelf. The fieldwork was carried out during the spring tides, from November/2004 until December/2005. Hydrographic measurements were made by a CTD and data were interpolated at 0.5 m depth intervals. Hydrographic structure was analyzed by the vertical profiles and T-S Diagram. Nutrients were sampled at surface, midwater and close to the bottom. The time-space variation of the average values obtained at each station was analyzed based on the hydrographic data. The channel waters represented an important source of nutrients to the bay. Whatever the hydrographic structure, these inputs occurs through the channel plume along the whole year, enhanced by rainfall events.
