A Map showing the locations where CTD data were collected for the WOCE dataset. B Sound speed profile in the North Pacific at 150°W longitude and 30°N latitude, comparing calculated (solid line) and predicted (dashed line) sound speed values. C Error distribution heatmap, where the color intensity indicates the number of predictions falling within specific error ranges. D Variation of Mean Absolute Error (MAE) with depth, illustrating the model’s accuracy across different depths.
