内容記述 | The nitrogen cycling was calculated in Manila Bay during dry and rainy seasons. The primary production in rainy season is higher than that in dry season. The main source of DIN (Dissolved Inorganic Nitrogen) is decomposition in dry season and the advective and diffusive flux from the lower layer in rainy season. River discharge and primary production are small in dry season, and the estuarine circulation is weak. The nitrogen cycling is closed in the upper layer in dry season. On the other hand, river discharge and primary production in rainy season are large. Therefore DIN is assimilated by phytoplankton, and phytoplankton is grazed by zooplankton and/or is moralized, and sank to the lower layer. DIN is regenerated in the lower layer, and is transported to the upper layer due to the strong estuarine circulation. Nitrogen cycling is closed in the upper and lower layers in rainy season. The residence time of TN (Total Nitrogen) in the upper layer in dry season is longer than that in rainy season. Nitrogen is used slowly and many times due to small nitrogen supply and weak estuarine circulation in dry season. But nitrogen is sufficiently supplied, is used quickly by primary production and is also quickly flowed out by strong estuarine circulation in rainy season. | |||||
