NIFS announced that it is going to provide water temperature prediction service in full swings from May of this year with the algorithms that it developed by combining artificial intelligence and sea surface temperature data obtained from satellite observations for improving the accuracy of water temperature prediction technology.

The algorithms, where a ConvLSTM* was applied, has continued to improve the prediction accuracy through AI learning reflecting region-specific characteristics including East Sea, West Sea, South Sea, East China Sea, etc. In practice, the prediction accuracy has been improved from 90% in 2024 to 94% up to the present time through the algorithm improvement.

*A Convolutional LSTM (ConvLSTM)- a deep learning method for time series prediction- is a type of neural network that combines Convolution Neural Network(CNN) and Long-Short Term Memory(LSTM).

The water temperature prediction algorithms this time are expected to enable preemptive response to the fisheries disasters caused by abnormal ocean conditions such as high water temperature, low water temperature, cold water mass, etc. as well as to expand scientific bases for reducing fisheries damages. In addition, the related technologies are also expected to contribute to upgrading the overall level of ocean science and technology.
