Dissolved Nutrient Balance and Net Ecosystem Metabolism Using a Simple Box Model in Gamak Bay, Korea

Abstract

The budgets of fresh water, salt and nutrients were estimated in order to clarify the characteristics of material cycle in the Gamak Bay in 2006 with Simple Box budget Model. Outflow volume of freshwater into system was approximately-174.2~72.5×10 3 m 3 /day. Inflow masses of DIP and DIN were approximately 397.0~1158 mole/day and 1750~8328 mole/day, respectively. The Source or sink of DIP was under the control of the variation of fresh water budget in the system. the mass balance and NEM was largely determined by flushing time of material.
