Expertise: Coastal Physical Oceanography

Biography:

Dr Mohd Fadzil is the Deputy Director of Research and Consultation at the Institute of Oceanography and Environment (INOS), Universiti Malaysia Terengganu. His research interest is in coastal physical oceanography, with emphasis on field observation and numerical modelling. He has played an active role in examining the southern south china sea, particularly in terms of ocean currents, wind, wave and its water masses. The most important aspect of his study is the dynamics of upwelling system in the southern South China Sea. His involvment with number of reserach projects under the IOC/WESTPAC has allowed him to establish regional networks under the SEAGOOS (South East Asia Global Ocean Observation System). So far he is involved with two main regional projects involving the ocean forecast system (OFS) and the upwelling studies and ocean data integration project where he serve as the project leader.

Title: Exploring 100 years of Oceanographic Data in the Southern South China Sea

Abstract:

World Ocean Database (WOD) provides over 6 decades of oceanographic data especially for physical and chemical parameter. This availability of data has provided a valuable information for oceanography studies. This study which will used data coverage from 1916-2016 will focused on the specific region of Southern South China Sea (SSCS) which range of 0-10oN, 100-117oE. The area is part of broad and shallow continental shelf with depth characteristics only reach 80m, only the site near northwest of Borneo has a deep section. This area are also known for its seasonal variability that are dominate by seasonal monsoon; northeast Monsoon (NEM) and Southwest Monsoon (SWM) and ENSO phenomena.The average analysis shown that in general, May recorded the highest SST which is 29.751°C while January recorded the lowest which is 26.573°C in accordance to general annual pattern where SST increased from January to May and thenstarting to decrease until December. Long term analysis of temperature show increasing trends for the past 60 years which reflect the global trend of increasing ocean temperature caused by global warming. The study used transect analysis to show numbers of interesting features in the region such as thermocline changes and upwelling. For temperature profile at a chosen transects, NEM season poses a well-mixed layer compared to SWM that poses high stratification of water temperature. Thermocline study reveals the seasonal variations between the perspective areas. During January/September, the thermocline range is smaller (1oC)/larger (4oC) with the depth of 5m/20m at East Coast Peninsula Malaysia (ECPM). During January/September, the thermocline range is smaller (2oC)/larger (6oC) with depth of 10m/20m at Sabah-Sarawak (SS).Focusing on upwelling features, ECPM/SS occurs during SWM/NEM. Near ECPM,hotspot areas for upwelling features ranged at 3-4oN, 104-105oE while 5-6oN, 15-16oE for SS. This variety of range in thermocline layers according to area and seasons has given a bigger picture on the different strength of upwelling effect on different region. There is more can be explored using this huge amount of data which will be so valuable in providing fresh understanding of the study region which is not well understood.
