“…The chlorophyll amount per unit volume of sea water in the Kuroshio area is of the order common in the unproductive open oceans, while that in the Oyashio area , corresponds to the values in moderately productive waters (TALLING 1961).…”

: The primary productivity in the northwestern Pacific was discussed on the basis of the results obtained during the summer cruise in 1961. 1) Vertical stratification of phytoplankton was clearly recognized in the Oyashio area as well as in the Kuroshio area. Maximal chlorophyll concentration in water occurred at the depth where the light intensity reduced to ca. 10% or slightly less of the surface intensity. Chlorophyll amount for the entire euphotic zone in the Kuroshio area, the Oyashio area, and the mixed water region was 25-45, 50-70, and 40-55 mg/m2, respectively, and that in a littoral region of the Kuroshio, ca. 120 mg/m2. 2) Differentiation of photosynthetic pattern into sun and shade types, and light inhibition in photosynthesis were evidently observed, the facts being in good accordance with the results in 1960. 3) Photosynthetic rate for the surface samples from the Kuroshio, the Oyashio, and the mixed water region was at optimal light intensity 0.6-2. 0,3. 5-6.0, and 2.2-4.0 mgC/chl.mg/h, respectively. 4) Daily gross production for the entire euphotic zone was estimated by the chlorophyll method. The values calculated for three weather conditions, clear, slightly clouded, and clouded, were respectively O. 36, 0. 29, and 0. 16 gC/m2/day in the Kuroshio area, and O. 83, O. 72, and 0.49 gC/m2/day in the Oyashio area. 5) The Kuroshio area differed strictly from the Oyashio area in the concentration of phosphate in waters. The ratio of nitrogen to phosphorus in the sea water was anomalously small over all the areas surveyed, especially in the Kuroshio area. Such nutrient conditions might be responsible in part for the difference between the Kuroshio and the Oyashio areas in photosynthetic rate and standing crop of phytoplankton, and consequently in the primary productivity.

“…Aquatic ecologists (e.g., Steeman Nielsen, 1957;TaIling, 1961) pioneered in the use of chlorophyll estimation to describe the community. The result was that depth distributions of chlorophyll, light, and production rate were found to be roughly related, but not well enough to estimate standing crop or metabolic density from chlorophyll indices (Goldman and Carter, 1965).…”

“…The second growth chamber experiment tested all combinations of three levels of light intensity (600, 900, & 2,000 ft-c) and NT (10,17, & 30 C) on plants at a DT of 30 C. The higher light intensities increased leaf production, leaf size, and plant weights, but decreased the average life span of leaves. In this experiment each unit of leaf area yielded nearly the same amount of dry matter regardless of light intensity; shorter life spans of leaves apparently offset higher photosynthetic rates at 900 and 2,000 ft-c light intensity.…”

“…As pointed out by TaIling (17), the carbon increase indicated by plant growth represents the integration of net photosynthesis with time. Therefore, rate measurements of these two processes should contribute to a better understanding of environmental effects on growth.…”
