麗水近海의 海況特性에 관한 硏究 = A Study on the Oceanograhpic Conditional Characteristics of Yeosu Coastal Areas

다국어 초록 (Multilingual Abstract)

This study was done for the purpose of effectively preserving the fishing grounding which are existing and will be newly established in Yeosu coastal areas. Accordingly, the oceanegrahic conditional characteristics of these areas were investigated in February, May, September and November, 4 times each year from 1984 to 1985, that results are as follows:
1. The mean water temperature was high by 24.4℃ in Deukyang Bay in September 1984 and low by 3.8℃ in Yeoja Bay in February 1985. In comparison of water temperature with common year, it was high by 0.2~1.1℃ in February and May and low by 0.3~1.1℃ in September and November 1984, and 1ow by 1.2~2.0℃ in February to November 1985.
2. The distribution of salinity was 14.8~34.0‰ for two years:14.8~33.9‰ in 1984 and 31.2~34.0% in 1985. The mean distribution was low by 29.2‰ in September 1984 and high by 33.6% in February 1985. The distributions in each coastal area were low by 23.1% in KwangyangBay in September 1984 and high by 33.9% in the external sea of Keumsan area.
In comparison of saliaity with common year, it was low by 0.2~2.0‰ in May, September and November 1984 and high by 0.5~l.6‰ in February, May and September 1985. It was high by 0.2~O.7‰ respective1y.
3. The distribution of dissolved oxygen was 3.2~88㏄/ℓ for two years : 3.5~7.8㏄/ℓ in 1984 and 3.2~88㏄/ℓ in 1985. The distribution were high by 0.7㏄/ℓ in February and low by 7.4㏄/ℓ in September 1984 and high by 7.4㏄/ℓ and low by 4.5㏄/ℓ in May 1985. The distributions in each coastal area were high by 8.4㏄/ℓ in Gamag Bay and low by 3.9㏄/ℓ in Kwangyang Bay in 1985. 1n comparison of distribution with common year, it was low by 0.1~O.3㏄/ℓ in 1984 and high by 0.2~0.6㏄/ℓ in 1985.
4.The distribution of PO_4-P was 0.Ol~5.O8㎍-at/ℓ for two years: 0.O1~5.48㎍-at/ℓ in 1984 and 0.01~3.44㎍-at/ℓ in 1985. The distribution was high by 1.65㎍-at/ℓ in Kwanyang Bay in November 1985 and low by 1.65㎍-at/ℓ in the external sea of Keumsan area.
5. The distribution of NO_2-N was 0.01~ll.7㎍-at/ℓ for two years : 0.01~8.48㎍-at/ℓ in 1984 and 0.02~ll.79㎍-at/ℓ in 1985. The distribution was low by 0.02㎍-at/ℓ in Gamag Bay in September 1984 and high by 5.32㎍-at/ℓ in Kwangyang Bay in September 1985.
6. The distribution of SiO_2-Si was 0.18~71.5㎍-at/ℓ for two year 036~71.50㎍-at/ℓ in 1984 and 0.18~27.18㎍-at/ℓ in 1985. The distributions were high by 31.81㎍-at/ℓ in Kwangyang Bay in September 1985 and low by 1.5~3㎍-at/ℓ in Yeoja Bay in May 1985.
