Finger convection is observed experimentally in an electrodeposition cell in
which a destabilizing gradient of copper ions is maintained against a
stabilizing temperature gradient. This double-diffusive system shows finger
convection even if the total density stratification is unstable. Finger
convection is replaced by an ordinary convection roll if convection is fast
enough to prevent sufficient heat diffusion between neighboring fingers, or if
the thermal buoyancy force is less than 1/30 of the compositional buoyancy
force. At the transition, the ion transport is larger than without an opposing
temperature gradient
