Abstract

This study was carried out at Brunei Bay in 13th and 14th December 2005 and 22nd and 23rd August 2006. It was aimed at investigating the fluctuations of seawater properties(salinity, temperature, dissolved oxygen and pH) in the bay during two monsoon seasons, the Northeast Monsoon and the Southwest Monsoon. These parameters were measured using Hydrolab at a 15 randomly oceanographic stations at the bay. The salinity was less than 29.8 %0 during the Northeast Monsoon. It increased during the Southwest Monsoon highest salinity recorded was 3 0.44%0. Strong currents from open sea supplied high saline water and formed strong stratification during the Northeast Monsoon. Sea surface temperature increased due to seasonal effect. The temperature ranged between 29.94 °c- 30.74 °c during the Southwest Monsoon and lower seawater temperature during Northeast Monsoon with range between 26.7 °c - 28.8 °C. DO concentrations range between 2 mg/L - 6.5 mg/L during the NEM, compared to DO concentration during the SWM which was more uniformed with 4.59 mg/L - 5.89 mg/L at 3 m depth and 5.03 mg/L - 5.82 mg/L at 1 m depth. During the NEM, pH was less than 8.8, while during the Southwest Monsoon pH scattered uniformed with lowest pH reading was 7.75 and highest pH reading was 7.86.
