In summer 2010, we measured the concentration of dissolved oxygen (DO) and nutrients in the water collected at the bottom of Cheonsu Bay, off the west coast of Korea. We also measured nutrient fluxes across the sediment-water interface by deploying a fully-automated benthic lander, which collected t...

anoxic는 무엇인가? | 일반적으로 수괴의 용존산소(DO, dissolved oxygen)가 전혀 없는 경우를 anoxic(무산소)이라 하고, hypoxia(빈산소)는 용존산소 2 mg/L 이하인 상태를 말한다(Bianchi et al., 2010; Fleddum et al. | |

천수만의 해수 특징은? | 1). 만 내부의 해수는 반일주조인 조류에 의해 남쪽의 좁은 만 입구를 통해 외해수와 교환된다. 안면도 북단과 태안반도 사이의 좁은 수로를 통한 해수 유통은 무시할 정도로 작은 규모이다. 만 내부에서 조차는 대조기 6.3 m, 소조기 2.9 m, 평균 조차 4.6 m이며, 조류속은 중앙부 조류곡에서 낙조류 0.7 m s-1이고 창조류 1.1 m s-1이다(Choi, 2004). 천수만 저층의 퇴적물은 방조제 건설후 급속하게 니질 퇴적상으로 변하여 최근에는 천수만의 대다수 지역이 니질 퇴적상을 나타낸다(Lee and Park, 1998). |
