内容記述 | The seasonal variability of the water quality at Hurun Bay, the southern coastal area of Sumatra, Indonesia was investigated based on the data of physical (temperature, salinity, transparency), chemical (pH, DO, BOD5, TOM, DIN, DIP) and biological (plankton) parameters during 2001-2004. The observation results show that the water quality at Hurun Bay has changed toward the eutrophication. The gradual increment of the organic mater seems to have influenced on the decreasing of water transparency and DO, and the increasing of DIN and TOM. The main factors of the organic enhancement at Hurun Bay were the aquaculture activities, precipitation, mixing and coastal upwelling. Seasonal variability of water quality at Hurun Bay was associated with the monsoonal system in which high precipitation and warm water throughflow during the northwest (NW) monsoon caused increasing water temperature and DIN, generated phytoplankton bloom, and decreased salinity and transparency. The horizontal and vertical mixing in both transition periods of northwest to southeast monsoon (Tr-I) and its reverse (Tr-II), and coastal upwelling in the transition period of SE to NW (Tr-II) have caused decreasing water temperature and transparency, and increasing salinity, DIN and DIP. Water temperature and precipitation are the important parameters for phytoplankton bloom in Hurun Bay. The diatom (chaetoceros, rhizosolenia, nitzschia and bacteriastum) and dinophyceae (ceratium, protoperidinium and pyrodinium) were the most dominant species phytoplankton at Hurun Bay. | |||||
