Abstract

The spreading Cocuoainim polykikoides bloom in the southern coastal waters of Korea was simulated using numerical model including the physical processes of water flow and the chemical processes of increasing cell of C. polykikoides by uptake of dissolved nutrients. The circulation of sea water was simulated by two dimensional tide model reflecting the main four tidal components of $M_2,\;S_2,\;K_1,\;O_1$, and permanent current was driven by inflow/outflow across open boundaries. According to the result of model which tidal and permanent current were reflected simultaneously, eastward flows entering the southern waters from the western waters of Korea are dominant but westward flows are weak relatively. These result suggest that it is difficult for initial C. polykikoides bloom generated in the coastal waters of Goheung to move to the western coast of Korea through Jeju Strait. For spreading model of C. poiyhikoides, the range of generating distribution and the generating time of C. polykikoides bloom in coastal area are similar to those of observation data in the field. Wind is the most important factor in moving and distribution of red tide. Permanent current flowing eastward is also considered to be important factor and tidal current was a little influenced.

본 연구에서는 한국 남해안의 적조발생상황을 기초자료로하여 적조생물의 증식과정, 해수순환의 물리학적인 과정 및 영양염류를 고려한 생물학적인 과정 등을 동시에 고려한 적조발생모델을 구축하여 적조발생상황을 수치모델로써 재현하고자 하였다. 수치모델을 통하여 해류를 재현한 결과, 거제도 남쪽해역에서 나타나는 반원형의 해류분포는 그 해역에서의 급격한 수심변화에 의해서 생성되는 것으로 조사되었다. 조류와 해류를 동시에 고려한 해수순환모델 결과, 제주해협에서는 남해로 유입되는 동향류가 우세한 반면에 남해에서 서해쪽으로 유출되는 서향류의 세기는 미약한 것으로 나타났다. 이러한 결과는 고흥연안에서 최초로 발생한 적조가 제주해협을 통하여 서해쪽으로 이동하기 어렵게 만드는 원인중의 하나라고 판단된다 조류와 해류가 적조발생분포에 미치는 영향을 수치실험을 통하여 조사하였는데, 적조발생분포가 왕복성조류의 형태와 해류에 의한 외해쪽으로의 이동양상을 모두 포함하고 있었다. 그러나, 계산결과는 실제 적조 발생분포를 잘 재현하지는 못하였다. 그러나. 한국 남해연안에서 부는 서남서방향의 가상바람을 적용하여 계산한 결과. 전체적인 적조의 발생 범위와 이동시기는 비교적 유사하게 재현할 수 있었다. 또한, 적조의 이동 및 확산분포에 가장 큰 영향을 미치는 것은 서남서 방향의 바람의 영향으로 연구되었다.
