Physical characteristics of Redang Island Water

Abstract

The study of physical characteristics of Redang Island water was conducted at Redang Island, Terengganu, during end of March, 2009. The physical parameter of Redang Island, which are temperature, salinity, dissolved oxygen and current was collected from eight transects around Redang Island, where each transect consist of four stations. The temperature, salinity and dissolved oxygen data was measured by using YSI 6600 multiparameter while the current circulation data was measured by using Acoustic doppler current profiler. The graph of Depth vs temperature, Depth vs salinity, Temperature vs salinity and Depth vs dissolved oxygen and was plotted using Microsoft excel and the graph of current flow and current speed was plotted using Matlab software. The temperature and salinity distribution at Redang island are consistent. The obvious thermocline and halocline layers occurred at transect 2. The DO concentration are constant at all stations. The results showed that the current at the transects which facing the Terengganu mainland flow eastward while at the opposite transect, the current flow westward. The current speed are higher at surface and slower at the middle water and surface water.
