Distribution of organic materials in the surface sediments was investigated in September 1983 in Chinhae Bay System. Bottom waters containing less than 1㎖/ℓ of dissolved oxygen were found in Masan Bay, and in part of Kohyonsong Bay and Wonmunpo Bay. Organic carbon content in the surface sediments of Masan Bay was about 25㎎/g and it decreased with increasing distance from the inner Masan Bay. Mean organic carbon contents in Wonmunpo Bay and Kohyonsong Bay were 26.48 and 31.39㎎/g, respectively, which are higher values than those in Masan Bay where large amount of domestic and industrial wastewaters are discharged into the surface water and extensive phytoplankton bloom occurs almost year round. Mean organic nitrogen and pheophytin contents were also the highest in Kohyonsong Bay among eight subareas. In Masan Bay, settling of organic materials on the surface sediments seemed to be not significant because of active tidal mixing and relatively small size of particulate materials. In Kohyonsong Bay and Wonmunpo Bay large fecal pellets produced in shellfish farms could he easily settled down on the sediment because of weak current regime. DO content in the bottom waters were low in the organic material rich areas, and that suggests biodegradation of organic materials in the surface sediments could be an important oxygen consuming process during the study period of September 1983.

Vertical and horizontal distributions of chemical oceanograthic parameters were measured in Jinhae Bay in July, 1983. On the Masan-Gadeog section, high amounts of dissolved nitrates, ammonia, chlorophylla-a, and particulate carbon and nitrogen were observed in waters with low salinity. In the inner Masan Bay, high concentrations of dissolved ammonia and phosphates were shown. The C/N ratio in the surface waters was higer in the outer bay. Concentrations of dissolved inorganic nitrogen and phosphates in the surface waters seemed to be sufficient for red tides to occur.

Studies on the distribution of nitrogenous compounds, and respiratory oxygen consumption rate were carried out in Masan Bay, Korea where large amount of industrial and domestic wastewaters are discharged. In August 1986 the surface layer was significantly influenced by freshwater input. Below the seasonal pycnocline, an oxygen-deficient condition developed in a large area of Masan Bay. Concentrations of DIN, DON and PN were 735.6, 1261.8 and 48.5 umol/l at the head, and 79.1, 73.0 and 39.5 umol/l at the mouth of the inner Masan Bay, respectively. Phytoplankton carbon production was 2,695 mgC/m$^2$/day at the mouth of inner Masan Bay. Dissolved oxygen contents were lower than 1 ml/l from 3 m depth in inner Masan Bay and from 10 m depth in the outer Masan Bay. The high concentration of ammonium and phosphate in the lower layer suggests the active degradation of organic materials in the bottom waters and leaching from sediments. The ERS activity was 232.1 ul O$_2$/l/h in the surface waters of the innermost part of Masan Bay and respiratory oxygen consumption is likely to proceed at a rate of 442 ml O$_2$/m$^2$/day in the bottom waters of this bay. Nitrate removal rate was estimated to be 0.25 umol/l/day via denitrification in the bottom waters of the Masan Waterway. It is estimated from the ETS activity that, at the mouth of inner Masan Bay, 9.3-10.5% of carbon fixed in the upper layer was decomposed below the themocline.

1983년 하계에 진해만 전역에 대한 조사결과 마산내만, 행암만, 고현성만 등에서 저층수종의 용존산소량이 1ml/1 이하로 용존산소 결핍현상을 나타냈다. 이러한 현상은 하계에 수온 약층의 발달과 저층수로의 유기물 침강현상과 밀접한 관계에 있는 것으로 보인다. 1986년 하계에 ETS 활동도를 이용한 산소소비율 측정에서는 마산내안 저층수에서 442mlO₂/㎡/day로 나타났으며 해저퇴적물에서는 138-197mlO₂/㎡/day였다. 이러한 높은 용존산소의 소비율은 표층으로부터의 산소공급이 적은 하계에 저층수중 무산소환경을 쉽게 일으키게 되어 수산자원에 막대한 피해를 줄 것이라고 생각된다.
