울산만 내측과 외측에서 계절적 환경요인의 변화에 의한 식물플랑크톤 성장 및 분포

Abstract

To assess the relationship between environmental factors and seasonal phytoplankton community structure, we investigated abiotic and biotic factors in Ulsan Bay, Korea. We divided the bay into two areas based on geographical characteristics and compared the difference in each factor between inner bay and outer bay with t-test statistics.Our results demonstrated that Ulsan Bay was strongly affected by freshwater from Tae-wha River during the rainy season and by the surface warm water current from the offshore of the bay during dry season. These two external factors might play important roles in determine the seasonal phytoplankton community structures. and compared the difference in each factor between inner bay and outer bay with t-test statistics.Our results demonstrated that Ulsan Bay was strongly affected by freshwater from Tae-wha River during the rainy season and by the surface warm water current from the offshore of the bay during dry season.
