| 概要 |
Field observations were conducted to reveal the seasonal variation of particulate organic nitrogen (PON) in the Tsushima Straits. The concentration of PON was roughly equivalent level to that of disso...lved inorganic nitrogen (DIN; nitrate+nitrite) from the surface to the subsurface layer throughout the year. The PON in. March was the highest concentration among the months. The ratio of POC/PON (6.4) was nearly the same value as the Redfield ratio (6.6), and the PON concentration significantly correlated to the chlorophyll α concentration, suggesting that most particulate organic matter was composed of phytoplankton. Horizontal transport of PON through the eastern channel of the Tsushima Straits was compared with that of DIN. The ratio of PON transport to total nitrogen (DIN+PON) transport was 66, 36, 25 and 16% in March, June, September and November, respectively. Since the penetration of organic matter through the Tsushima Straits becomes a consequential nutrient load because of decomposition of inorganic matter in the Japan Sea, oceanographic conditions including organic matter should be monitored in the Tsushima Straits.続きを見る
