Periodicity in phytoplankton population as well as phytoplankton abundance and physico-chemical factors affecting the abundance and periodicity were investigated in this study. Quantitative and qualitative sampling was carried out between August 2004 and November 2004 at two sampling stations located at the UMS jetty area. Three divisions of marine phytoplankton were identified which are Bacillariophyta, Pyrrophyta and Cyanophyta. Fifty five species of marine phytoplankton were identified during this study with Bacillariophyta a:; the dominant species in terms of total species number and cell density during the research period. The highest phytoplankton abundance was determined in the month of October 2004. Phytoplankton diversity declined to the lowest level in the month of November 2004. Phytoplankton cell numbers found in this study were lower than those previously reported and in contrast to many previous findings carried out at Sepanggar Bay. A significant positive relationship was found between salinity and phytoplankton abundance (r=0.68, p<O.OS). In general, significant negative relationships were found between phytoplankton abundance and abiotic factors which are as pH (r = -0.15, p<0.05); DO (r = -0.50, p<O.OS); turbidity (r = -0.13, p<0.05) and temperature (r= -0.29, p<O.OS).
