Vertically oscillating mesh grid forms a homogeneous patch of mixed fluid within a linearly stratified tank of salt water. The entire tank is rotating and as the patch adjusts due to buoyancy forcing, a anti-cyclonic geostrophic eddy forms. This phenomenon is thought to drive horizontal dispersion at pycnocline depths in ocean shelf waters.
