142 the mountain closer to the gorge between the mountains (edge of the ridge y=0.28Н), the black dye was supplied from the opposite edge of the mountain at a distance y=- 0.28Н. The results of visual researches (Fig. 4a) showed that the colored jets used to visualize the flow do not reach the top of the Atlantis II seamount model, but go around the mountain model (red and black dye on one side of the top of the mountain). The jets of red dye separated near the supply of this dye near the frontal surface of the mountain into two directions: one rose along the front surface of the mountain to its top, and the second, more intense, went to the bottom part of the seamount, as shown in Fig. 4a. The upper part of the red dye, not reaching the crest of the seamount, oscillated around the top of the mountain at a distance of about 0.05H, and then, expanding, began to form a vortex structure that rose to the level of the top of the mountain in its aft part and had dimensions of approximately x=0.15H and z=0.1H. In front of this vortex structure, at a distance of about 0.5H, a large-scale vortex structure, colored red, was observed, which had a longitudinal dimension of x=0.75H and a vertical scale of z=0.5H. This large-scale vortex structure, rotating with a frequency of the order of (0.3-0.6) Hz, rose to approximately the height of the top of the seamount and, scattering, formed a large-scale non-vortex cloud, which approached the free surface of the water in the channel and had a longitudinal dimension of about 1.5H and a vertical dimension of (0.75-1)H. The jets of black dyes, oscillating and curving around the lateral surface of the mountain top at a height of about 0.5H, split into two, clearly visible in Fig. 4a, one of them, continuing to oscillate, reached almost the level of the seamount crest in its aft part, and then gradually descended to the bottom part of the mountain, and the other, oscillating, also headed towards the bottom of the channel, and its small part formed a non-intensive circulation flow in the near wake of the middle-height aft part of the seamount model. It should be noted that near the bottom of the channel at a distance of about (1.75-2)H, a large-scale cloud of non-intensive colored dyes was also observed, which consisted of a mixture of red and black colors and, from our
