DESCRIPTION:Though thermohaline staircases exist in a large region of the 
 Arctic\, the interactions of such staircases with shear and turbulence is 
 a topic that has only seen substantial exploration in the last few years. 
 Our research has focused on the interactions between these staircases with
  shear\, such as that generated by internal waves or intrusions. This work
  is done using a spectral numerical code with a dynamic mesh that is perfe
 ctly suited for studying small-scale turbulent processes in regions of lar
 ge-scale shear. We have performed a series of two- and three-dimensional s
 imulations with and without shear and demonstrate the capacity of shear to
  both form and disrupt Arctic staircases. Both isotropic shear and unidire
 ctional oscillating shear are considered. In cases of strong shear\, we sh
 ow that these staircases can be disrupted\, though they are remarkably res
 ilient if the shear is intermittent. In cases of weak shear (Richardson nu
 mbers greater than 2)\, the spontaneous development of layers is observed.
