莞島東部沿岸의 海洋特性에 關한 硏究 = On the Oceanographical Characteristics of the Eastern Sea Waters Near Wando Island

다국어 초록 (Multilingual Abstract)

An investigation on the physical and chemical condition of the eastern sea waters of Wando Island had been carried out during from February, 1985 to November, 1988, and the followings are the results.
Water temperature ranged from 4.9 to 26.4℃. The inner sea waters was lower as much as 2℃ in winter, but higher as much as 1∼3℃ in summer than the outer sea waters.
Salinity ranged from 23.60 to 34.21‰, highest in February and lowest in September, and there was the greatest salinity fluctuation near Shinji(St. 1) on the account of the influx of land water.
Dissolved oxygen content ranged from 3.56ml/l, high at st. 1 that is the site of inner sea, but low at outer sea, and highest in February and lowest in August.
The phosphate concentration ranged from 0.10 to 0.98㎍-at/l, the dissolved inorganic nitrogen (DIN) ranged from 0.54 to 7.67 ㎍-at/l, high in spring and low in September, and gradually increased annually.
Transparency was in the range of 0.4∼11.0m, low at st.1 and high at st.5 the is located in the outer sea.
The concentration of total suspended solids was in the range of 1.2∼53.6mg/l, This showed reverse distribution to the transparency, and its relationship to the transparency at st.5 was S=11.4087-1.2946T(r=0.6577).
The distribution rate between DIN and PO_4-P was more stable at bottom that at surf ace and more stable in outer sea than in inner sea waters as well.
