Abstract
    Marine environments of the Gulf of Yeong-illocated in the East Sea of Korea are naturally influenced by topography, climate, and both of cold and warm currents, and artifically by waste waters induced from Pohang City and mammoth iron industry. Near the Gulf of Yeong-il the cold water ma,sses collide with the warm Tsushima Current (a branch of the Kuroshio), and result many interesting problems: upwelling phenomena, water blooms, forming optimal fisheries and diverse hydrological variations etc. Intense marine pollutions give often gigantic red tides, particularly in summer. Consequently, these pollutions must be controlled in order to conserve marine water resourses and ecological equilibrium. Physico-chemical and biological parameters are measured for this study: climatical parameters (winds etc), temperature, salinity, density, pH, alkalinity, dissolved oxygen (%saturation), BOO, COD, phosphates, nitrates, diverse chlorophylls, phaeopigments, heavy metals, phytoplanktons and zooplanktons, benthos etc. According to the measured parameters, 7 water mass groups are identified. This first note corresponds to the introduction of each parameters of the serial researches.
