Abstract :
Temporal analysis is used to obtain changes in water quality along the Straits of Johor. Boxplot is used to show graphically on the temporal pattern of yearly and monthly temperature, conductivity, pH, dissolved oxygen (DO), total suspended solids (TSS) and oil and grease in the water from 2003 to 2013. The ANOVA test is carried out to determine the significance of the mean of each parameter between years. The boxplot shows a particular trend for each of the marine parameters over the year and the seasonal pattern is only apparent in temperature. The ANOVA test indicates a significant difference in the means of each water quality marine parameter across the year. The changes in each of the marine parameters over the year could be associated to the natural features of the marine water and climate change. The seasonal pattern however is only apparent in temperature which could be influenced by the monsoon seasons.
