Abstract

In respect of the nutrients cycling in coastal environment, regeneration in bottom layer is one of major source of nutrients. We analyzed the bottom water quality at the 14 stations during 9 years from 2004 to 2012 to investigate the characteristics of nutrients at bottom layer in Jinhae Bay. Concentrations of DIN, DIP and DSi showed the large seasonal variation and were higher in summer. Especially, average concentrations of these nutrients were two times higher in hypoxic season than in normoxic season. In summer, high concentrations of DIN, DIP and DSi caused by regeneration were common feature, but spatial distribution of DSi differ from that of DIN and DIP. DIN and DIP were higher in Masan Bay, while DSi was higher in Masan Bay as well as in center of Jinhae Bay. In comparison with DIN and DIP, DSi was significantly affected by nutrients regeneration at bottom layer in whole season. According to time series analysis, DIN concentration was decreased from approximately $14{\mu}M$ to $6{\mu}M$. This result induce that Si:N ratio at bottom layer in Jinhae Bay changed from approximately 1 to 3.

연안환경의 영양염 순환에서 저층에서의 영양염 재생산(regeneration)은 주요한 영양염 공급원 중 하나이다. 진해만 저층 영양염의 거동을 살펴보기 위해 2004년부터 2012년까지 9년간 진해만 내 14개 정점의 수질자료를 분석하였다. 저층의 용존무기질소, 인산염인, 규산염규소는 계절적 변동성을 나타내었고, 하계에 가장 높은 농도를 보였다. 특히, 빈산소 수괴(hypoxia) 형성 시기의 평균 영양염 농도는 정상산소상태(normoxia) 시기에 비해 약 2배 더 높게 나타났다. 하계 진해만의 저층 용존무기질소, 인산염인, 규산염규소의 농도는 재생산에 의해 모두 높은 경향을 보였으나, 공간적 농도 분포는 차이를 나타내었다. 용존무기질소와 인산염인은 마산만에서 가장 높은 농도를 보이는 반면 규산염규소는 마산만 뿐만 아니라 진해만 중심부에서도 높은 농도를 나타내었다. 또한 다른 영양염에 비해 규산염규소는 전 계절 동안 저층에서의 재생산이 큰 영향을 미치는 것으로 나타났다. 시계열 분석 결과 9년간 용존무기질소의 농도는 약 $14{\mu}M$에서 $6{\mu}M$로 뚜렷한 감소를 나타내었다. 용존무기질소의 감소로 인해 진해만 저층의 Si/N 비는 약 1에서 3으로 증가된 것으로 나타났다.
