Journal of Marine Research, 69, 57–77, 2011 Secondary instability of salt sheets by Satoshi Kimura1,2 and William Smyth1 ABSTRACT In the presence of a vertically varying horizontal current (background shear), the salt-fingering instability is supplanted by the salt-sheet instability. WebAdditional data reveals that the ratio of the salt flux to the product of viscosity and local density gradient due to temperature is about one. This result supports the collective instability model of Stern (1969), which provided a mechanism for the breakdown of the fingers and the limitation of the finger interface thickness.
