An alteration of the segment-slope in the fine size classes (1.59-10.08 µm in the coastal region, 1.59-6.35 µm in the open sea) was assumed to show a loss or a supply of fine particles due to aggregation or disaggregation. We studied relationships between segment slopes, static stabilities of water above the pycnocline which concern the dynamics of particles, and C/N ratios as an indicator of freshness of particles. A negative correlation between the segment-slope of particle size distribution and static stability was obtained, though the slope P of the regression line varied from 0.059 to 0.316. The average C/N ratio in the waters were in the range of 7.5 to 16.3. The slope P negatively correlated to the C/N ratio (r=−0.97). The present results suggested that aggregations of fine-sized particles in the sea are activated in the water with fresh organic matter and with high static stability. the Oceanographical Society of Japan, 1989 Kawakita Michimasa Faculty of Fisheries, Hokkaido University, Minato 3-1-1, 041, Hakodate, Japan aut Kajihara Masahiro Faculty of Fisheries, Hokkaido University, Minato 3-1-1, 041, Hakodate, Japan aut Journal of the Oceanographical Society of Japan Kluwer Academic Publishers 46/1(1990-02-01), 1-8 0029-8131 46:1<1 1990 46 10872 https://doi.org/10.1007/BF02334219 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/BF02334219 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Kawakita Michimasa Faculty of Fisheries, Hokkaido University, Minato 3-1-1, 041, Hakodate, Japan aut NATIONALLICENCE 700 1- Kajihara Masahiro Faculty of Fisheries, Hokkaido University, Minato 3-1-1, 041, Hakodate, Japan aut NATIONALLICENCE 773 0- Journal of the Oceanographical Society of Japan Kluwer Academic Publishers 46/1(1990-02-01), 1-8 0029-8131 46:1<1 1990 46 10872 Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
