천수만의 지리적 특징은 무엇인가? | 서해안 중부지역에 위치한 천수만은 서측에 안면도가 위치해 있고, 북측에는 서산시와 태안군, 동측에는 보령시와 홍성군으로 둘러싸여 있으며, 만의 구조는 남북으로 길고 남측으로 주 해수유통이 이루어지며, 북측의 수로로 일부 해수가 유통하나 만의 해수교환에 큰 영향은 미치지 않는 반폐쇄성 구조로 이루어져 있다. 이러한 구조적 특성으로 많은 해양생물의 산란 및 생육장으로 높은 생산성을 가진다(KOSEF, 1993). | |
천수만의 해양 환경적 문제는 무엇이 있는가? | 천수만의 해양 환경적 문제는 북측에 위치한 간월호와 부남호로부터 하계 강우시 대량의 담수유출로 인한 급격한 환경변화가 있고, 또한 인근 지역에서 배출되는 생활폐수, 농경지에서 사용된 화학비료의 유출로 인하여 해양의 수질 환경의 악화를 들 수 있다. 하계 방조제로부터의 담수유출은 내측 표층의 저염분수괴 형성 및 수층 성층화로 해수의 혼합을 저해함으로써 만내 부영양화 촉진 및 간헐적 적조가 발생하였다. | |
서해 천수만의 낙조류 최대 유속은 얼마인가? | 주조류로를 중심으로 좌우에 폭 1~5 km에 달하는 넓은 조간대가 발달되어 있다. 대조시 주조류로에서 측정된 창조류의 최대유속은 약 110 cm/sec, 낙조류 최대유속은 약 80 cm/sec로 유속의 비대칭흐름을 가지고 있다(Lim et al., 2002). |
