145 side of the Atlantis II seamount model to its side in the form of a shapeless cloud and, in part, descended to the bottom of the front wall. Rounding the side of the mountain, the red dye cloud moved in the direction of the flow, and at a distance of about (1.7- 1.9)H, increasing in volume and combining with the black dyes, it began to move to the median longitudinal section in the wake of the seamount. The black dye, emerging from its source in the form of a jet, began to go around the seamount from its side and oscillate, gradually increasing the amplitude of the oscillatory motion. At a distance of about (1.9-2.2)H, the black dye began to move to the central longitudinal axis of the seamount and merge with the red dye, forming a large-scale colored cloud. The stream of green dye, upon reaching the lateral surface of the seamount model, significantly expanded and went around the lateral side of the mountain, and behind it, in the form of a green colored cloud, moved in the direction of the flow and gradually degenerated and dispersed (see, Fig. 5b). Conclusions. The simulated flow interacting with the seamount, which was a bluff body, underwent significant changes due to the separation flow with the rough surface of the seamount. As a result, vortex, jet and wave flows were generated, formed and transported into the seamount wake and the near-surface and near-bottom layers. The results of visual researches showed that the Gulf Stream flow simulated in laboratory conditions had characteristic features that were determined by the depth of its interaction with the seamount. Thus, at a depth not exceeding a third of the height of the mountain, the simulated flow rose along the frontal surface of the rough model of the seamount to its top, and then vortex, jet and wave flows were formed in the wake of the upper part of the mountain. It was established that at a depth of 0.35 of the height of the mountain, the simulated flow in the longitudinal axial section of the seamount model bifurcated. During visualization at the level of half the height of the mountain, it was registered that the colored jets did not rise to the upper part of the mountain, but, flowing around it from the sides, were directed to its bottom part.
