Ekman’s dead water experiments reproduced with modern technology by French experimentalists in the laboratory of physics at of Lyon. The three-layer fluid system was used as the model(distinguished by red, white and yellow from top to bottom). The of each layer was 5.0 cm, 3.0 cm, and 5.5 cm respectively, and the density was 0.9967 g/cm$^3$, 1.0079 g/cm$^3$, and 1.0201 g/cm$^3$. The model ship sails from left to right, and snapshots from top to bottom show the position of the model as well as the internal wave profiles at different times
