초록
1999년 3월, 7월, 9월 및 11월에 섬진강 하구역에서 염분경사에 따른 영양염의 거동을 조사하였다. 조사 정점은 지리적 위치보다는 각 조사시마다 표층 염분을 현장에서 측정하여 결정하였다. 질산 질소와 규산 규소의 주요 공급원은 섬진강이었으며 아질산 질소와 인산 인은 섬진강 하구입구와 인접한 광양만에서 배출되는 도시하수와 공장폐수에 영향을 받고 있는 것으로 나타났다. 암모니아 질소는 난초도로부터 약
Behavior of nutrients along the salinity gradients in the Seomjin River estuary was investigated in March July, September and November, 1999. Sampling sites were set based on the surface salinity during each cruise rather than geographic locations. The results suggest that source of nitrate and silicate was the Seomjin River discharge, while that of nitrite and phosphate was waste disposal from the Gwangynng Bay near the mouth of Seomjin River estuary. Ammonia was supplied inside the estuary at the region about
