When ice forms on lakes, dissolved salts are rejected, which can lead to under-ice salt-finger formation. We performed a series of laboratory experiments visualize these fingers. While we detected salt-fingers in our camera recordings, the signal fingers is nearly absent temperature record. quantify velocity salt plumes and measure bottom salinity increase from Further, estimate that often dist...

Numerical simulations and linear stability analyses of expanding cellular monolayers suggest cell–substrate friction is responsible for fingers at the edge. A critical contractile stress characterises wetting-dewetting; dewetting inhibits fingering.
