| Research Abstract |
Influences of global warming on estuarine environments were investigated from the points of view of meteorological and oceanographic variations, changes in nutrient inflow from land and estuarine water quality.
For meteorological variation, congestion of chemicals tend to occur because of enhancement in stratification near the ground surface from night to early morning. For oceanographic variation, detailed research on the 2009 storm surge indicates that the drastic change in wind field may increase magnitude of storm surge in the bay. For nutrient inflow from rivers, increase in freshwater discharge induced by extraordinary rainfall may cause increase in nutrients inflow. For estuarine water quality, the field data showed that water temperature has increased 0.024 to 0.06 degrees per year and also that the change in wind may influence upwelling characteristics of oxygen depleted waters in shallow waters.
