Most coastal upwelling regions are governed by classical wind-driven Ekman dynamics. In the semi-enclosed basin of the South China Sea (SCS), a number of these upwelling systems are found along the western boundary. It has been known that coastal upwelling occurs during the summer along the coast of Vietnam [1]-[3] and near Hainan Island [4] [5].With the summer monsoon being an important force in the region, south-westerly upwelling favourable wind provided the perfect setting for such features to occur. One such place is the east coast of Peninsular Malaysia (PM). Unlike the central and northern SCS, there have been very few published reports of upwelling off PM, i.e. [6] [7]. These early studies, however, covered a localized area, and the descriptions of the upwelling were brief. The available research so far are unable to draw a clear spatial coverage of upwelling presence along PM coast, which shows that the understanding of upwelling system in the region needs significant attention. Nevertheless, looking at the dynamic potential of Ekman dynamics presence during southwest monsoon, hypothetically the scale of upwelling formation along the coast can be relatively large given the length of the meridional coastline governed by PM. In this study, we found that the upwelling revealed by the in-situ data is actually only part of a larger upwelling system along the PM coast. Additionally, the southwest monsoon induces upwelling off the PM east coast, which is in accordance with the Ekman upwelling theory. Nevertheless, it is out of the study scope to conclude that this is the main or only factor influencing upwelling in the area. Most importantly, this study provides new insights regarding southwest monsoon dynamics that produce an upwelling system, which is known to be a particularly nutrient rich and high productivity process. It will best serve as the basis for future research in the area.
