Experimental modelling of the growth of tubular ice brinicles from brine flows under sea ice

Abstract. We present laboratory experiments on the growth of a tubular ice structure surrounding a plume of cold brine that descends under gravity into water with a higher freezing point. Brinicles are geological analogues of these structures found under sea ice in the polar regions on Earth. They may be important for the energy budget of sea ice. Brinicles are hypothesized to exist in the oceans of other celestial bodies, and being environments rich in minerals, serve a potentially analogous role as an ecosystem on icy ocean worlds to that of submarine hydrothermal vents on Earth.

Short summary
Brinicles are ice tubular structures that grow under the sea ice in cold regions. This happens because the salty water going downwards from the sea ice is colder than the sea water. We have recreated succesfully an analogue of these structures in our laboratory. Three methods were used, producing different results. In this paper we explain how to use these methods, study the behaviour of the brinicles created when changing the flow of water, as well as their importance for natural brinicles.
