In the surface layer of Sagami Bay, the concentrations of phosphate, total inorganic nitrogen, and silicate showed seasonal fluctuations in the range of 0.02-0.7 μg at. P l-1, less than 1.0-11 μg at. N l-1, and less than 5-25 μg at. Si l-1. The following relation has been found for these elements:
P:N:Si=1:12.7:19.7
The infusion of cold water into the subsurface layer was one of the important sources supplying considerable amounts of inorganic nutrients to the euphotic zone, particularly in summer. The amount of chlorophyll a varied widely throughout the year, and no consistent relationship between the seasonal changes of chl. a and the nutrients was observed.
