| 内容記述 | Spatial distribution of macronutrients such as nitrate-N, phosphate-P and silicate-Si in the region around the Kurile Islands in August-September, 1990 was studied. Negative relationships between nutrient concentrations and temperature were observed in the surface water for a range from 5 to 15˚C in nitrate-N and silicate-Si, and from 5 to 20℃ in phosphate-P, respectively. Based on the physical characteristics of water, this region was divided into five areas: Oyashio, Kuroshio, Warm Core Ring, Okhotsk and Kurile Islands areas. Abundant nutrients were observed in the Warm Core Ring and the Kurile Islands area compared with the other three areas. Atom ratio of nutrients (N: Si: P) was variable in the surface water compared with a relatively constant value (N: Si: P=15: 22: 1) at 800m. Nutroclines were well developed within thermocline and pycnocline at most stations. However nutroclines for three nutrient species were deeper than thermocline and pycnocline in the Kuroshio area. The mean ratio of gradients of nutrocline as N: Si: P was 14: 22: 1 in the region studied. When this ratio was compared with the Redfield ratio, this ratio suggests that silicate-Si may be supplied exessively compared with the supply of nitrate-N and phosphate-P to the surface layer. Particularly this phenomenon was remarkable in the Okhotsk area. The reason for the ample supply of silicate-Si in the Okhotsk area is discussed. | |||||||||||||||||||||||
