Short summary
We used a simplified model to investigate how changes in abyssal stratification can impact the propagation of vortices in the ocean. Although abyssal stratification is typically considered stable, observations have shown that this is not always a good approximation. We found that changes in deep stratification can introduce variability into the patterns of the vortices. Despite the assumptions made in our model, our results are supported by seafloor observations in the Ionian Sea.
