Salt fingering
From Glossary of Meteorology
salt fingering
A form of double-diffusive convection that occurs when warm, salty water overlies cold freshwater.
A parcel of freshwater moved upward will gain heat more quickly than it gains salt and so will become lighter than the surrounding water. It will rise unstably as a result. Salt fingering has been observed in the Caribbean Sea where it gives rise to stable layers hundreds of kilometers in extent. The process transports salt much more efficiently than heat.
