Abstract:
This study was conducted to analyze and determine current circulation pattern and
physical characteristics ofBidong Island water from data collected on June 2011. The insitu
data was collected by using Hydrolab Quanta and Acoustic Doppler Current Profiler
(ADCP). The data was analyzed by using MATLAB software and Microsoft Excel. The
data were grouped into Group A, Group B, Group C and Group D in order to determine
the geographical influence towards current circulation pattern, temperature and salinity.
From the result obtained, temperature values were from 25.56 to 29.84 °C. Group B
recorded lower temperature while temperature distributions of Group D were highest.
Salinity in Bidong Island was from 32.49 to 33.52 ppt. Distributions of salinity were
almost constant except for Group B. Results showed stratification layer at Bidong Island.
Current circulation profile was almost constant in directions and speeds from surface to 5
m. Currents move in mix direction, suspected to be result of deflection and recirculation.
Most of currents were directed to northwest and southwest. Currents at upper side of
Bidong Island which was Group A and Group C were more consistent in direction than
Group B and Group D. Inconsistent of current circulation area were surrounded near
Karah Island in which below Bidong Island. It is suspected that there is geographical
influenced between the islands.
