“…The description of water circulation and exchange patterns in tropical and subtropical coastal waters is therefore crucial to the understanding of ecosystem dynamics and global ocean flux studies (Bowman, 1997;Swenson and Chuang, 1983;Ho, 1977). Hydrodynamics in coastal reef areas are thought to be the most complicated phenomena if the reef areas become connected or remain exposed to the open ocean (Nakaza et al, 2006). A number of research studies have already conducted on a variety of coral reefs.…”

Summer and wintertime observations were conducted through deploying horizontal oceanographic time series sensors in a coral reef region of Southwest Japan to assess the existing hydrodynamic and thermal environments in relation to seasonal changes. A significant variation in water circulation and temperature distribution pattern was recorded in Shiraho reef area between two different seasons. During winter, a strong inflow of oceanic water was recorded inside the reef on a semidiurnal pattern that led to significant water temperature rising while in summer, considerable amount of sea water entered the reef area with a diurnal frequency causing water temperature slightly lower. Outside the reef, current was found to flow nearly parallel in direction to the north-south stretch of the reef.
