| 内容記述 | In the present paper the distribution of nutrient salts and chlorophyll-a in the warm water mass originating from the Kuroshio water were investigated. The results are as follows: 1) The distribution patterns of phosphate and nitrate in the large type warm water mass ejected directly from the Kuroshio current are equivalent to those in the Kuroshio water. The lower limit of the warm water mass corresponds to the equivalent lines of 1.0 μg-at/l in phosphate and also of 15 μg-at/l in nitrate which correspond to those in the Kuroshio water at a depth of hundreds of meters. 2) Phosphate and nitrate at the lower limit of the medium and small scale warm water masses originating from the Kuroshio Branch (northward stretch of the high temperature and salinity water from the Kuroshio current) are 1.5 μg-at/l and 20 μg-at/l respectively and these values are more or less higher than those of the large scale warm water mass. 3) Values of these kinds of salt in the warm water mass entering into the Oyashio water show homogeneous distribution of 1.0~1.2 μg-at/l in phosphate and 10~20 μg-at/ l in nitrate, and these values are similar to those at the lower limit of the warm water mass observed in the mixing area. 4) The average value from surfce to 100 meters depth of chlorophyll-a in the large scale warm water mass observed in 1972 was tens of mg/m2 in spring, decreased to 10 mg/m2 in summer and in autumn it increased again to tens of mg/m2. 5) The change of chlorophyll-a from spring to autumn in the large type warm water mass (observed in 1972) seems to correspond closely to that of observed amount of nitrate consumption. | |||||||||||
