| Abstract | This study aimed to observe and simulate a process that releases heat from shallow and deep waters in the AcehWaters. The simulations modeled vertical slice cases with varying seawater densities based on stability frequency. One transectwas taken in shallow waters in Krueng Raba Bay, while the other two were taken in deep waters in Sabang Bay. This study useda 2D non-hydrostatic model with stratified densities from the sea surface to the specified depth. Seawater density changesincrease in areas with shallow depth and leave low-density in the high depth area. The vertical current velocity or upwelling startsto strengthen in the sill area at two hours, in the simulation. The lighter fluid moves upwards, looking for a gap in the denser fluidon the surface, at a speed of 0.0042 m/s to 0.03 m/s. Areas with high depth have these speeds falling after about 3 hours in thesimulation, but the surface layer shows seawater density stability. In general, the deep sea area is not affected by the convectionprocess, and the sea surface area is well-mixed after 3 hours of simulation. |
