抄録

The data of chemical components observed in seawater of the northwestern part of Tokyo Bay during 1980-1988 (except 1985) were arranged and their fluctuations were discussed. In surface water at the station locating off the coast of Haneda, the conentrations of phosphate and total inorganic nitrogen showed seasonal fluctuations in the range of n.d.-8.7μg at-P•1^-1 and 0.8-310 μg at-N•1^-1. Those of dissolved organic carbon, particulate organic carbon and chlorophyll a varied also seasonally in the range of 0.9-5.8mg-C•1^-1, 0.1-18mg-C•1^-1 and 0.7-750μg•1^-1, respectively. From the station locating in estuary of the Arakawa River to that near the center of the bay, the concentrations of inorganic nutrients decreased remarkably than organic components. The atomic ratio of N/P ranged from 17 to 380 in surface layer at the station off Haneda and showed a trend to increase gradually during 1980 to 1988, indicating that nitrogen excess in the nutritional condition was proceeding.
