As a basic study to improve oxygen deficient water mass(ODW), this study analyzed the spatial and temporal variation of the water quality and investigated the characteristics of ODW in Jinhae bay, from 1989 to 2006 by observing the annual variation of water qualities, the severe polluted area was found, and the effects of a special management sea area in Masan bay and the construction of Pusan Newport on the water qualities was investigated. Finally, we estimated ODW_are, ODW_vol. and ODW_R in Jinhae bay. From the study, it is shown that overall water quality at 2000s has been improved by investigating the variations of dissolved oxygen, chemical oxygen demand, etc. From cluster analysis, Jinhae bay was classified into four regions. The four regions were defined as Southern, Central, Northern, and Eastern. ODW was occurred in all areas of Region I in 1993 and 2002~2004. ODW were not occurred in Region Ⅳ because seawater was well exchanged in the eastern part of Jinhae bay. On the other hand, ODW was generated every year in Region I, this means the southern part is the most polluted area in Jinhae bay. ODW_R was decreased in Region Ⅲ hence, it is shown that water quality of Region Ⅲ has been improved since operating wastewater treatment plant in 1994.
