Brinicles as a case of inverse chemical gardens

Brinicles are hollow tubes of ice from centimeters to meters in length that form under floating
sea ice in the polar oceans when dense, cold brine drains downward from sea ice to
seawater close to its freezing point. When this extremely cold brine leaves the ice, it freezes
the water it comes into contact with: a hollow tube of ice? a brinicle? growing downward
around the plume of descending brine. We show that brinicles can be understood as a form
of the self-assembled tubular precipitation structures termed chemical gardens, which are ...
