ABSTRACT
ContextThe Beritoga Channel is located near Sao Paul'o Brazil and is approximately 30 kilometers long. It separates the mainland from the island of Santo Amaro, and is more strategically located nearer to the city of Guarujá. The Beritoga Channel is a natural marina .
Aims/ ResultsBeritoga Channel is unique. It is a mixed (type 2) tidal estuary on the coastal plain of Sao Paulo, Brazil. However, although past papers in 1965, 1978, studied this channel the primary reason for these studies were related to the exploration for petroleum based products, and the first comprehensive study did not take place until 1991. However, an important factor that was not studied was how the tidal wave action brings into The Beritoga Channel an influx of saline conditions into the channel waters. The 1991 study did not address how the tidal Wave action and influx of saline conditions affects the channel's nutrients and phytoplankton distribution. Although, there were additional studies in 2000, this last comprehensive study was more than 13 years ago and another should accomplished in 2013-2014 as soon as possible. Therefore, it is the intent and purpose of this paper to help bring about a larger awareness how important such a study is. In order to seriously determine to a much better extent to what extents the nutrients and phytoplankton has been affected in The Beritoga Channel of Brazil.

1.0 Introduction and Background
1.1 A Need for Re-Assessment of Some of The Past Published Data
There were studies of the Beritoga Channel in 1965,1978 that were necessitated by petroleum interests in the Brazil region. The first study did not take place until [1]- R. Herz et al (1991) performed it in studying the tidal circulation of Beritoga Bay. The 1991 study yielded data yielded information about the physical structure of the system. Peak -channel velocities were and designated to be varied from 40 cm s-' to 60 cm s-I during flood tides and from 70 cm s-' to 100 cm s-I during ebb tides.What was significant at that time in 1991 is that this study was able to determine that the upstream influx of saline conditions into the Beritoga Channel in Brazil. Which could be affecting the channel's...
