The Fukuoka Prefectural Fisheries Experimental Station has been carrying out oceanographic observations on a fixed line in the East Tsushima Strait since 1913. Seasonal and secular changes in water temperature were investigated based on these data from 1919 to 1979. The deviations from the mean water temperature were large in summer, especially in the thermocline layer at 50m. Abnormally high temperatures appear from spring to autumn whereas abnormally low temperature appears from autumn to spring. The secular variation of water temperature in the East Tsushima Strait shows a 6-or 8-year periodicity from 1919 to 1943 and a 6-year periodicity after 1948.
