Topographic Rossby Waves

The seaward edge of the continental shelf, or shelf break, is the locus of strong physical variability in the overlying waters. Near the shelf-break, surface tides scatter energy into internal modes that propagate both onshore and offshore and produce strong vertical shears. Atmospheric forcing generates subinertial-frequency topographic Rossby waves, which propagate parallel to the coastline and are strongly trapped near the shelf break. Relative to the sloping topography, wind-driven coastal upwelling generates prograde fronts, and river run-off generates retrograde fronts. Located near the shelf break, these fronts are boundaries between oceanic and coastal waters. Oceanic eddies impinge on, and move along, the shelf-break entraining coastal waters. Eddies may also be shed by shelf-break fronts. Submarine capes and canyons contort the shelf break and significantly modify the enumerated processes. Based on observational evidence from a few coastal regimes, the shelf break is a zone where several mesoscale and synoptic-scale processes operate and probably produce significant turbulent transfers.

High Recruitment

Bays in coastal upwelling regions are physically driven and biochemically fueled by their interaction with open coastal waters. Wind-driven flow over the shelf imposes a circulation in the bay, which is also influenced by local wind stress and thermal bay–ocean density differences. Three types of bays are recognized based on the degree of exposure to coastal currents and winds (wide-open bays, square bays, and elongated bays), and the characteristic circulation and stratification patterns of each type are described. Retention of upwelled waters in bays allows for dense phytoplankton blooms that support productive bay ecosystems. Retention is also important for the accumulation of larvae, which accounts for high recruitment in bays. In addition, bays are coupled to the shelf ecosystem through export of plankton-rich waters during relaxation events. Ocean acidification and deoxygenation are a concern in bays because local extrema can develop beneath strong stratification.

Current Circulation

The hydrographic characteristics and current circulation in Terengganu and Pahang coastal waters were examined for their spatial and temporal variability based on the seasonal influence during the transition period (April 2014) and southwest monsoon (June and August, 2014). The results of this study demonstrated the presence of slightly cooler water during June and August, 2014 compared to April, 2014, which indicate the existence of coastal upwelling. Furthermore, the uplifting of isotherms towards the coast during the study trip was also a good evidence of upwelling. The current flow generated by the wind was the possible reason of the features. Furthermore, this study also makes the first attempt to observe the coupling effects between coastal upwelling and the phytoplankton biomass in Terengganu and Pahang coastal waters, which is still sparse. Interestingly, apart from the nutrient availability, the coastal upwelling was believed to influence the phytoplankton biomass at the study area.
