Distribution of urea and dissolved organic matter were surveyed in the two brackish coastal lagoons, Hwajinpo and Yungrangho in August 1978. Concentration of urea was in the range of 0.5 to 3.9 ㎍-atN/ℓ and showed similar pattern of distribution to that of ammonia. The atomic ratio of dssolved organic carbon and dissolved organic nitrogen to dissolved organic phosphorus was 560 : 70 : 1 in Hwajinpo and 740 : 75 : 1 in Yungrangho. In both of the lagoons salinity did not show significant correlation with urea and dissolved organic matter. In the Yungrangho vertical distribution of dissolved oxygen concentration did not show significant correlation with DOC, DON. and. DOP, either. Comprising 0.15 to 1.37 percent of dissolved organic carbon and 2.9 to 20.9 percent of dissolved organic nitrogen, urea which is very susceptible to biological uptake and depletion as nitrogen source of phytoplankton seems to be an important constituent of, dissolved organic matter in brackish lagoons.
