Last winter, it was found that the sea temperature in our waters was higher than the average. The National Institute of Fisheries Science reported that the analysis of sea temperature changes in our waters from December of last year to March of this year showed that the sea temperature was about 1℃ higher than the average for the same period in previous years. The average sea temperature during this period was recorded at 0.5 to 1.5℃ higher than the average, and except for the latter half of January when a cold wave appeared due to the influence of cold air from the north, the sea temperature in most areas remained higher than both the average and the previous year. The average surface sea temperature based on satellite observation data was 12.3℃, which is 1.14℃ higher than the average and 0.98℃ higher than last year. In particular, the coastal area of the South Sea, which was 0.47℃ lower than the average last year, was 1.53℃ higher this year, showing a noticeable increase in ...
