Cyanobacteria were most abundant in the surface of the subtropical water (36.5-38.0°N) and less in the northern sea area (39.5-44.0°N). The cell density of other picophytoplankton was, however, high in the northern part and low in the subtropical water. Results showed that algae other than cyanobacteria may significantly contribute to the picophytoplankton community under the low water temperature conditions of open waters. Chlorophylla concentration represented well the abundance of picophytoplankton other than cyanobacteria, but had no significant correlation with the cyanobacteria cell density. Chlorophylla-based data must be interpreted with caution, since the abundances of cyanobacteria were often considerably different even though the chlorophylla concentrations were the same level. the Oceanographical Society of Japan, 1989 Odate Tsuneo Division of Marine Biochemical Science, Research Institute of North Pacific Fisheries, Faculty of Fisheries, Hokkaido University, 3-1-1 Minato-cho, 041, Hakodate, Japan aut Yanada Mitsuru Division of Marine Biochemical Science, Research Institute of North Pacific Fisheries, Faculty of Fisheries, Hokkaido University, 3-1-1 Minato-cho, 041, Hakodate, Japan aut Castillo Lourdes Division of Marine Biochemical Science, Research Institute of North Pacific Fisheries, Faculty of Fisheries, Hokkaido University, 3-1-1 Minato-cho, 041, Hakodate, Japan aut Maita Yoshiaki Division of Marine Biochemical Science, Research Institute of North Pacific Fisheries, Faculty of Fisheries, Hokkaido University, 3-1-1 Minato-cho, 041, Hakodate, Japan aut Journal of the Oceanographical Society of Japan Kluwer Academic Publishers 46/4(1990-08-01), 184-189 0029-8131 46:4<184 1990 46 10872 https://doi.org/10.1007/BF02125579 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/BF02125579 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Odate Tsuneo Division of Marine Biochemical Science, Research Institute of North Pacific Fisheries, Faculty of Fisheries, Hokkaido University, 3-1-1 Minato-cho, 041, Hakodate, Japan aut NATIONALLICENCE 700 1- Yanada Mitsuru Division of Marine Biochemical Science, Research Institute of North Pacific Fisheries, Faculty of Fisheries, Hokkaido University, 3-1-1 Minato-cho, 041, Hakodate, Japan aut NATIONALLICENCE 700 1- Castillo Lourdes Division of Marine Biochemical Science, Research Institute of North Pacific Fisheries, Faculty of Fisheries, Hokkaido University, 3-1-1 Minato-cho, 041, Hakodate, Japan aut NATIONALLICENCE 700 1- Maita Yoshiaki Division of Marine Biochemical Science, Research Institute of North Pacific Fisheries, Faculty of Fisheries, Hokkaido University, 3-1-1 Minato-cho, 041, Hakodate, Japan aut NATIONALLICENCE 773 0- Journal of the Oceanographical Society of Japan Kluwer Academic Publishers 46/4(1990-08-01), 184-189 0029-8131 46:4<184 1990 46 10872 Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
