Foraminifera zonation and water renewal in transects along Bertioga Channel, SP, Brazil

Patr Cia P. B. Eichler

Abstract :

The purpose of this research is to correlate modern distribution of foraminifera with environmental parameters in transects to evaluate microhabitats and geohabitats along and across Bertioga channel. We show zonation of foraminiferal species to salinity changes, temperature, currents and sedimentological characteristics correlating with renewal capacity of its estuarine waters. The western mouth that receives polluted water from the Santos Bay, shows signs of environmental degradation because their renewal rate is average, on the other hand, the south inner part is in more problematic situation, as its waters have low efficiency rate of renew.
