ABSTRACT
Many rivers discharge into Santa Cruz Channel (27º 49’ S Lat., 34º 50’ W Long.) which
separates Intamaracá Island from the continent of South America. Water samples were collected
monthly at five fixed stations, in three different depths, for physical-chemical analysis
(temperature, transparency, dissolved oxygen, pH, salinity, nitrite-N, nitrate-N, phosphate-P and
suspended material), phytoplankton biomass (chlorophyll a, fractionization) and primary
production This work presents only the primary production results; as other parameters by me
appear in the other reports and are referred to for a comparison because the samples were
collected together. The primary production of the phytoplankton during the studied period was
relatively high, varying from 0,94 to 76.59mgC/h/m3 (averege value was 17.68mgC/h/m3).
