Self-propelled, submerged bodies travelling in thermohaline staircases generate evident temperature and velocity perturbations on the surface of the ocean, which may lead to possible airborne detection methods of underwater vehicles from above. This paper presents numerical simulations of a submerged body traveling in a staircase environment, to better understand the dynamics that occur underwater and on the surface. Previous studies of selfpropelled submerged bodies focused on the surface signatures of the late wake in a homogeneous or uniformly stratified fluid. However, this study will concentrate on the effects of the late wake in thermohaline staircases, an environment in which thermal signatures are more pronounced due to higher vertical heat transport compared to smooth gradients in the absence of staircases.
